www.jbj.co.uk/couplings.html #DriveLineHarmony ® SERLOCK 79 ® ® SERLOCK is the new patented, keyless self locking bushing for immediate use with all power transmission components suitable for the SER-SIT , T/L or similar tapered bushings: ® » Is directly interchangeable with SER-SIT or T/L tapered bushings. » Available in 1108, 1210, 1610, 2012, 2517, 3020 sizes. » With bore diameters from 12 to 70 mm according to the bush sizes. » Allows infinite axial and angular adjustments. ® ® SERLOCK is an innovative clamping system which combines all the advantages of SIT-LOCK friction keyless bushings with the extensive availability of a wide range of PT components for tapered bushings such as: » V and Poly-V Pulleys. » Timing Pulleys. » Couplings. » Sprockets. ® SERLOCK eliminates: » All problems related to conventional keyway systems (backlash, breakage, fretting corrosion, difficult disassembly, restrained axial and angular positioning of the component on the shaft). » Additional machining on the component to be fixed on the shaft, required when using conventional cone/clamping elements. With the following benefits: » Immediate availability of the system (element to be clamped + advanced clamping system). » Easy assembly and disassembly. » Possibility of reducing the diameter of the shafts used by up to 25%. » Easy angular and axial adjustment of the component with respect to the shaft. ® » Possibility of using SERLOCK also on shafts with keyway. All this means an immediate advantage for the user as a result of the potential increase in productivity. Assembly is extremely simple and fast: ® 1) Couple the SERLOCK bushing to the hub by means of the two set screws; 2) Position the part on the shaft in the required axial and angular position; 3) Gradually tighten the set screws until the torque Ms, indicated in the technical tables, is achieved; 4) Tighten the clamping screws gradually and evenly according to the cross outline until the torque Ms, indicated in the technical tables is achieved. ® Note: Do not lubricate the SERLOCK bushing or the shaft on which it is mounted.
