SRMCR5D750L50Z32A0M1L12

The SRMCR5D750L50Z32A0M1L12 belongs to the MCR Radial Piston Motors series manufactured by Bosch Rexroth and is intended to drive heavy hydraulic equipment with precise speed control. Its displacement of 750 cm³ per revolution establishes the amount of fluid moved each cycle, directly governing flow rate and power output. A specific torque of 12 Nm per bar links operating pressure to delivered torque, while a peak figure of 3000 Nm shows the motor’s capacity to turn high-load shafts without stalling. The unit can start smoothly at 0.5 rpm, which supports inching or positioning duties, and it tolerates continuous running up to 240 rpm for standard travel speeds. A square flange with four SAE holes provides a rigid mounting surface that aligns the shaft and prevents misalignment under load. The complete assembly weighs 39 kg, so a single installer can handle it with ordinary lifting aids in most machine frames.

An inlet/outlet port thread of 1 1/16-12 UNF matches common high-pressure hose fittings, whereas both the case drain and filler ports use a 3/4-16 UNF thread to keep service tools consistent. The motor accommodates a maximum port pressure of 420 bar and a maximum differential pressure of 400 bar, giving a safety margin between static and working limits. Case drain pressure is limited to 10 bar so the internal seals are not overloaded. NBR sealing material provides chemical compatibility with standard hydraulic oils and maintains flexibility across typical operating temperatures. The design includes no through shaft, which simplifies housing construction and eliminates external shaft seals. Together, these characteristics allow the motor to withstand demanding circuit pressures, connect quickly to standardized plumbing, and retain fluid integrity during continuous industrial service.
