Low speed, high torque hydraulic motors available from jbj Techniques Limited

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. notsiplaidaR rotom tnemecalpsiD egnardeepS euqroT rewoP suounitnoc rewoP tnettimretni V xamg )ver/cc( V nimg )ver/cc( V xamg )mpr V nimg )mpr ( V xamg )rab/mN( V nimg )rab/mN( V xamg )Wk( V nimg )Wk( V xamg )Wk( V nimg )Wk( X052-057MR 847 942 054-5 006-01 1.11 6.3 07 22 09 82 X553-0001MR 7401 943 005-5 006-01 3.51 1.5 08 72 001 03 X041-0041MR 3341 341 053-5 005-01 0.12 0.2 08 01 001 51 X006-0081MR 0081 895 003-5 054-01 3.62 7.8 001 33 031 34 X0001-0003MR 8292 999 022-5 053-01 8.24 6.41 511 93 051 15 X0522-0054MR 2444 1222 041-5 082-01 1.56 5.23 021 06 061 08 notsiplaidaR rotom tnemecalpsiD mc( )U euqroT )mN( deepS )nim/1( erusserP )rab( rewoP )Wk( N08MR 08 882 008 052 21 N521MR 621 054 006 002 21 N061MR 161 985 008 052 42 N052MR 152 029 006 002 42 X052MR 552 439 006 052 82 X553MR 953 5131 055 052 63 X054MR 244 7161 005 052 04 X005MR 194 7971 054 052 04 X017MR 407 9752 005 052 36 X009MR 409 0133 054 052 36 X0001MR 7401 5283 056 052 521 X0521MR 6621 3364 045 052 521 X0041MR 7041 0515 005 052 031 X0061MR 8061 5785 034 052 031 X0081MR 0181 5266 093 052 031 X0002MR 1102 0637 053 052 031 X0052MR 3352 5729 013 052 541 X0513MR 7613 29511 052 052 541 X0004MR 3104 00741 002 052 051 X0054MR 8054 00561 571 052 051 X0005MR 8725 02391 051 052 051 Variable motors » The comprehensive RM range feature: » Choice of shafts » Double shaft extension » Motor and brake combinations » Geared motors; gear motor and brake combinations » Tachometer and other measuring attachments » Couplings, flanges » Viton seals » Special models for HFB and HFC non-flammable fluids » Direct valve assembly possible » Connection SAE J 518 high pressure (type: A1) ( Further information including pdf catalogues please go to www.jbj.co.uk or contact jbj Techniques Ltd technical office
