Skilled British engineers have been manufacturing the range of JXL anti-static couplings and cast iron bellhousings in the UK since 1984, specifically for use in hazardous areas. The cast iron range of bellhousings, prefix GG is also available in high strength (SG) iron, prefix GGG, in addition we produce this range to suit NEMA motor flange dimensions without the use of adaptor plates. These bellhousings are a one-piece component founded in the UK with minimal (trace) aluminium, magnesium, titanium and zirconium content*. Final machining is effected at jbj premises in Redhill; in some instances a steel flange may be bolted to the pump mounting face to facilitate the fitment of larger pumps. The bellhousings have been subject to a 20-Joule impact test with no damage noted. The JXL range of resilient couplings is able to accept angular, radial and axial misalignment, they are torsionally resilient, non lubricating and capable of operating between temperatures of –50°C and +105°C. The elements are flame resistant, anti-static and have NCB acceptance for use underground in coalmines number A2032. If required, housings can be supplied with full chemical analysis and test bars. This must be requested at the time of ordering. A surcharge will apply. SELECTION * Couplings are selected on their ability to transmit torque between rotating shafts, with restricting factors being maximum speed and shaft diameter. Calculate the torque to be transmitted, determine the required service factor with reference to the duty factor chart, multiply the relevant duty factors together to give the required service factor, multiply the calculated torque by this factor to give the required coupling rating. Select the coupling size with reference to the continuous value, taking into account the bore diameters required. * See selection notes for JXL couplings and cast iron bellhousings. 1 #DriveLineHarmony www.jbj.co.uk/bellhousings.html

JXL/GGR Selection Guide Equipment for Hazardous Areas Selection Notes for JXL Couplings & Cast Iron Bellhousings This is intended as a guide for the selection of bellhousings and couplings for the use in hazardous areas. Consider motor power and speed against coupling nominal torque. If the resilient bushes fail, metal-to-metal contact could occur, in order to minimise the risk of this situation, we recommend that the end user carry out periodic inspection of the coupling assembly with particular attention being applied to the resilient bushes. This can be further enhanced by the application of a large service factor to the coupling at the selection stage. By the nature of the design of JXL couplings, a large service factor is easy to achieve, as a general rule, a full compliment of resilient bushes with each coupling selection will naturally give a high service factor. Consider the site of the housing and coupling assembly. If the assembly is to be positioned in an inaccessible area where periodic inspection will be difficult to achieve or may be ‘overlooked’ a high service factor will be very desirable, in many cases the provision of a dia 50mm inspection hole in the bellhousing will save time when inspecting the coupling. Consider coupling clearance. When selecting JXL couplings for use inside bellhousings, consideration must be given to clearances between rotating and non-rotating parts, based on BSI 9-2000 EN50019: 2000-173, we recommend that this clearance be a minimum of 5.0 mm in all cases, however the standard this information is derived from advises that clearance shall be 1/100 of the maximum diameter (rotating component), but in no case shall the clearance be less than 1.0mm, reference to this could be used in special circumstances, however it is envisaged that 5.0mm should be possible in all cases. Consider vertical mounting. JXL coupling hubs are machined with an additional grub screw at 90 degrees to the grub screw over the key slot, this is to provide additional security against the hubs creeping down one or other shaft when mounted vertically, we strongly recommend the use of this additional grub screw in vertical installations, however, if the additional grub screw is not to be used, it must be removed from the coupling hub and an alternate method sought, eg pinning of shaft keys, spacers or clamp design hubs. Consider mining applications. In mining applications, it is not permitted to allow dust to enter equipment supplied, therefore any inspection holes in bellhousings must be fitted with solid covers. Consider pump removal. GGR bellhousings will be fitted with a centring to enable the pump to be removed without removal of the coupling hub from the pump shaft as standard, where the centring will not interfere with the pump fixing holes. In instances where the diameter of the centring would interfere with the pump fixing holes, provision of a removable pump face on the bellhousing may be required in order to assist with pump removal. This should be requested at time of quotation. 3 #DriveLineHarmony www.jbj.co.uk/couplings.html

Angular Misalignment All couplings, plus or minus 0.375° per hub maximum, 0.75° total. Axial Misalignment All couplings plus or minus 50% of flange gap (dimension C) When the coupling hubs are within the correct alignment fit the coupling pins, liners and resilient elements ensuring that each pin assembly has three washers fitted; one under the cap screw head and one at either end of the element. The pins should be fitted with the steel self locking nut adjacent to the resilient element. Where half or less number of pin assemblies are being used, all elements should be fitted into one flange. When all pin assemblies are fitted tighten the steel self locking nuts in pairs at 180° to each other to the correct torque. Ensure no rotating component is within 5.0mm of any non-rotating part. When the coupling assembly is to be mounted in a vertical position, we strongly recommend the use of the additional grub screw positioned at 90 degrees to the key slot, to reduce the risk of the coupling hubs creeping down the shafts. If the additional grub screw is not to be used it must be removed from the coupling hub. Tightening Torques for JXL Couplings Maintenance JXL Coupling Installation Equipment for Hazardous Areas Periodically check flange alignment and resilient elements for wear. Worn elements must be replaced. Misalignment must be rectified. Inspection and maintenance is the responsibility of the end user. Note All JXL couplings are capable of accepting a momentary overload of twice nominal torque and have an operating temperature range of -50°C to +105°C. TX note During operation bellhousings and JXL couplings do not generate heat therefore operational surface temperature will depend on the temperature of mating components and surroundings. Refer to BS EN 13463:1 9.3.2 f) Equipment ‘T’ class or maximum temperature (T max) to be determined by machine builder.

Ensure each flange is clean. Fit each flange to their respective shafts. Line-up coupling flanges by checking dimensions between flange faces and by using a straight edge across the outside diameter of flanges at 90° intervals. If possible a dial test indicator may be used to give accurate details of alignment. The flanges should be aligned to within the following tolerances noting that where one misalignment is present then the others must be reduced proportionally. Careful alignment will extend coupling life. Parallel Misalignment 6 #DriveLineHarmony www.jbj.co.uk/couplings.html
This guide is for the installation of JXL couplings when a bellhousing is used. Coupling pins are tightened to the correct torque prior to leaving our premises; these values should be re-checked prior to installation. Under no circumstances should the couplings be assembled with the pins tightened to any torque other than the specified values. Fit the relevant coupling hub onto the motor shaft. As a general rule the face of the coupling flange will be flush with the end of the motor shaft with any necessary offset being applied to the hub fitted to the pump shaft. In any case the correct setting distance must be maintained, tighten grub screw(s) and recheck the setting distance. Fit the pump centring to the pump (when supplied) then fit the relevant coupling hub to the pump shaft, position the hub suitably to obtain the correct setting distance, tighten grub screw(s) or clamp screw(s) if the pump has a spline shaft, and re-check the setting distance. When the coupling assembly is to be mounted in a vertical position, we strongly recommend the use of the additional grub screw positioned at 90 degrees to the key slot, to reduce the risk of the coupling hubs creeping down the shafts. If the additional grub screw is not to be used it must be removed from the coupling hub. Assemble the pump and motor to the bell housing ensuring that there is no loose matter i.e. grub screws washers etc remaining inside the housing and that no rotating component is within 5.0mm of any non rotating part. Tighten all bolts to the correct torque values. We recommend the use of shake proof washers with all bolts.

Engine Bellhousing and JXL Anti-Static Flame Proof Flywheel Coupling This guide is for the installation of JXL flywheel couplings when an engine bellhousing is used. The coupling pins are tightened to the correct torque prior to leaving jbj Techniques Ltd; these values should be re-checked prior to installation. Under no circumstances should the couplings be assembled with the pins tightened to any torque other than the specified values. Mounting In most cases the diameter of the hub is smaller than the centre locating diameter of the bellhousing. The hub passes through the bore in the bellhousing which connects the pump with the flywheel housing. In this case the installation can be carried out as follows: 1) Fit the drive flange to the engine flywheel and tighten bolts to engine manufacturers recommendations. 2) Fit the bellhousing to the engine flywheel housing and tighten bolts to engine manufacturers recommendations. 3) Fit the pump centring to the pump (when supplied) then fit the coupling hub to the pump shaft, position the hub suitably to obtain the correct setting distance, (see arrangement drawing if supplied), tighten grub screw(s) or L-Lock screw(s) if the pump has a splined shaft, and re-check the setting distance. Coupling hubs with cylindrical bores are supplied with an additional grub screw at 90° to the keyway. If the additional grub screw is not to be used it must be removed from the coupling hub. 4) Fit the pump and coupling hub to the bellhousing ensuring that there is no loose matter i.e. grub screws, washers, etc. remaining inside the housing and that no rotating component is within 5mm of any non rotating part. For the occasional case where the hub diameter is larger than the bore in the bellhousing, the installation should be carried out as follows: 1) Fit the drive flange to the engine flywheel and tighten bolts to engine manufacturer’s recommendations. 2) Fit the bellhousing to the pump. 3) Fit the coupling hub to the pump shaft, position the hub suitably to obtain the correct setting distance (see the arrangement drawing if supplied), tighten grub screw(s) or L-Lock screw(s) if the pump has a splined shaft and re-check the setting distance. Coupling hubs with cylindrical bores are supplied with an additional grub screw at 90° to the keyway. If the additional grub screw is not to be used it must be removed from the coupling hub. 4) Offer up the pump, coupling hub and bellhousing to the engine flywheel housing ensuring that there is no loose matter i.e. grub screws, washers, etc. remaining inside the housing and that no rotating component is within 5mm of any non-rotating component and tighten bolts to the engine manufacturer’s recommendations. Tighten all bolts to the correct torque values. We recommend the use of shake proof washers with all bolts. If the additional grub screw is not to be used it must be removed from the coupling hub.

Thermostatic Valve Equipment for Hazardous Areas Maximum water flow 70 litres/minute Not suitable for sea water All dimensions in mm unless stated Instructions for Installations and Use During the valve installation, never strain the fittings, to avoid deteriation of threads or possible gas or oil losses. In order to avoid incorrect operation the sensor element (bulb) must always be fitted below the valve body. The capillary tube, between bulb and valve body, should not be deformed by too narrow bends or angles, to allow free gas passage. The valve is adjusted in order to begin the opening phase around 77°F and to complete it around 122°F. Remaining in this range of values, to increase the opening temperature slightly turn adjusting knob clockwise. If water leakage takes place after the valve has been closed for a time, turn the adjusting knob clockwise until the leak stops. Note: Periodically check that no calcareous deposits have built up in the system. 20 #DriveLineHarmony www.jbj.co.uk/thermostatic-valve.html

» High power density - high power level considering the relatively small size. Axial piston motors are used in restricted space of precision cylindrical forgery machines to control the working hub onforgery tools. The strongest RM5000 radial piston motor can move weights of 100 tonnes in steelworks transport carts. » Jerk-free start up. Ideal in the operation of fire engine turntable ladders or fork-lift trucks which need to position heavy loads safely and quickly, often at extreme lifting heights. » Low operating noise of these hydraulic motors make them particularly suitable for stagecraft in theatres and opera houses » High axial and radial forces on the shaft permissible due to the very compact construction of these hydraulic motors combined with suitable roller bearings. For instance as a drive for screw pumps for highly viscose media. » High resistance to environmental influences makes these hydraulic motors ideal for rolling mills producing rolled steel bands, driven under temperatures of up to 90°C or the level control of offshore drilling platforms which are washed by salt water breakers. » The excellent control of speed and torque makes these hydraulic motors ideal for rewinder mechanisms in film blowing machines where freshly blown film must be spooled with constant traction so that the film does not rip and the thickness of the file remains constant. with fixed and with adjustable displacement according to Directive 94/9/EC. ATEX Many types of drives can fulfil the elementary function of driving a machine but . . . Düsterloh hydraulic motors have lots of additional features and characteristics which other types of drives cannot match. This is why Düsterloh hydraulic motors are the first choice for solving a wide variety of complex drive problems. Düsterloh hydraulic motors have a high starting torque. This is required for instance, for safe operation of the heavy gates on the material lock in a nuclear power plant or to hand over the weighty coils in a rolling mill. Due to the low amount of revolving mass, the rotational direction can be quickly changed in Düsterloh hydraulic motors. This feature is very important in many test benches; when performing vibration tests on motorcycle forks or when testing the adjustment of wing flaps on aircrafts. The components can perform up to 50 rotational direction changes per second. An exact adherance to the specified rotational speed profile is of essential importance for many fields of application of hydraulic motors. Düsterloh now presents a new generation of motors, for which a significantly improved constancy of rotational speed was achieved compared to conventional motors.

Design modifications in the flow control inside the motor as well as in the arrangement of the pistons have led to significant improvement of the constancy of the rotational speed. In addition, the speed range was clearly extended downwards. For the standard motor which is already precise in competitive -1 comparison, the ability to run is ensured for a minimum speed of 5 min . The high precision motor can achieve speeds of -1 significantly less than 1min with already good constancy of speed in unregulated operation. The -1 maximum speed is still up to 2000 min , depending on the motor size. AE series » KM series » available in a new High Precision version. Use as standard for stable speeds significantly less than 1rpm.

RM series » Radial piston motors Type RM80N - RM5000X 3 displacement 80 - 5278 cm /rev operating pressure 250 bar speed up to 800 rpm torque 288 - 19320 Nm The radial piston hydraulic motor has been designed with a high load capacity. It is efficient, has a low moment of inertia and is capable of very low speeds and has excellent reversing properties. The concept features make it extremely quiet, being suitable for servo control systems with facility to work either as a motor or pump in both directions. Drive Motor: consists of a close grain, high strength, cast iron cylinder block. Eccentric crankshaft concept. Operating characteristics: five radial piston/connecting rod assemblies bear on the crankshaft which is located by heavy duty tapered roller bearings. Crankshaft bearings: preloaded to take the thrust in both axial directions, ensuring silent running and allows heavy radial and axial loading on the output shaft (e.g. gear drives). Connecting rod: the computer optimated design is hydrostatically balanced on the crankshaft with sufficient leakage to ensure lubrication and cooling. Friction losses are reduced to a minimum and stick slip action is avoided at low speeds. High starting torque and running torque combined with high speeds are important features of the design. Long service life is assured since con-rod slippers are uneffected by contamination and self-adjustable. Non-flammable fluids have been used with success. Noise generation is also reduced by the cushioning effect of the hydrostatic bearing design.
