2.1.1.1 BMR series hydraulic motors General information BMR hydraulic motors are low speed orbital units with intermediate values of torque suited to work at low and medium loads. Motors’ housing made of ductile cast iron of adequate intensity, can be applied to situations with less load and interval operation. Gerotor mechanism equipped with rollers gives better start under load, and higher working poressures, as well as higher output torques. The rollers, however, reduce the maximum speeds of each model. Spool distribution valve gives longer working live under medium loads, and enables motor size reduction. Shaft ball bearing which is standard in BMR motors gives slightly higher resistance to axial and radial forces, and extends the motors working life. BMR motors are dedicated to agriculture, forestry, plastics, machine tools and mining machines, such as a mould height adjustment of an injection molding machine, the road cleaners, the saw, the worktable etc. Features: ź Low starting pressure; ź Reinforced shaft seal; ź Low noise level; ź Shaft ball bearing; ź Small size and easy startup.

BMR series hydraulic motors
General information
BMR hydraulic motors are low speed orbital units with intermediate values of torque suited to work at low and medium loads. Motors’ housing made of ductile cast iron of adequate intensity, can be applied to situations with less load and interval operation. Gerotor mechanism equipped with rollers gives better start under load, and higher working poressures, as well as higher output torques. The rollers, however, reduce the maximum speeds of each model. Spool distribution valve gives longer working live under medium loads, and enables motor size reduction. Shaft ball bearing which is standard in BMR
motors gives slightly higher resistance to axial and radial forces, and extends the motors working life. BMR motors are dedicated to agriculture, forestry, plastics, machine tools and mining machines, such as a mould height adjustment of an injection molding machine, the road cleaners, the saw, the worktable etc.
Features:ź Low starting pressure;ź Reinforced shaft seal;ź Low noise level;ź Shaft ball bearing;ź Small size and easy startup.
