BM5 is a large volume,disc valve ,high pressure motor,with ralial bearings design, and can bear greater load.
Characteristic features：
Advanced design in disc distribution flow, which can provide better performance at low speed.
The valve can automatically compensate for the wear, so the volumetric efficiency is high .
Double taper roller bearings permit high radial loads. The motors can be used on heavier vehicles in traction drive applications.
