Sunfab SCM M2 is a range of robust axial piston motors especially suitable for winch-, slewing-, wheel- and track drives. Sunfab SCM M2 is of the bent-axis type with spherical pistons. The design results in a compact motor with few moving parts, high starting torque and high reliability. Motor SCM 047–090 M2 GB The SCM M2 covers the entire displacement range 47–90.0. cm3/rev at a maximum working pressure of 40 ...MPa.. Sunfab SCM M2’s well dimensioned, double tapered roller bearings permit high shaft loads and lead to excellent speed characteristics. Intermittent power data are based on maximum continuous speed and maximum working pressure. Continuous power data are based on maximum output power without external cooling of the motor housing. Intermittent duty is defined as follows: max 6 seconds per minute, e g peak RPM when unloading or accelerating. Sunfab SCM M2’s high level of reliability is based on the choice of materials, hardening methods, surface structures and the quality assured manufacturing process.

Temperatures/Housing cooling Excessive system temperature reduces the life of the shaft seal and can lower the oil viscosity below the recommended level. A system temperature of 60 °C and a drain flow temperature of 90 °C must not be exceeded. Cooling/flushing of the motor housing can be needed to keep the drain flow temperature at an acceptable level. Suggested flow: Motor SCM Flushing l/min Cont.
