BMK6 series motors use a two-piece rotor design. Seven precision rollers added to the lobes of the outer ring of the gear set provide sliding contact points which act as roller bearings and reduce friction. This increases mechanical efficiency and reduces wear in systems specially with low fluid viscosity, requiring lower pressure at start-up and providing superior drive life and smoother performance at all speeds. The disc distributor valve has been separated from the output shaft and is driven synchronously by a dedicated short valve drive ensuring that the individual chambers of the motor are filled and emptied precisely. This allows for higher permissible pressure and torque. The output shaft supported by tapered roller bearings permit high axial and radial forces offering a smooth operation during low pressure start up and high-pressure operation. The BMK6 motors are offered in 8 displacements with torque up to 1230 lbf-ft. and 40 gpm continuous. These motors are packed with power and operate very smoothly.

BMK6 motors can be supplied with two mounting options:

1. The standard motor mount where the mounting flange is located as close to the output shaft as possible, supporting the motor close to the shaft load.
2. The wheel motor commonly used in traction drive applications. In the BMK6 wheel motor (W) the mounting flange is located closer to the center of the motor which permits part of the motor to be located inside the wheel or roller hub, positioning the load directly over the shaft bearing for best bearing life.

The BMK6 motors provide design flexibility in many applications with adequate torque and flow characteristics; these motors are packed with power while operating smoothly.
