SCM 025-108 M2

SCM 025-108 M2 is a range of robust axial piston motors with cartridge flange especially suitable for winch-, slewing-, wheel- and track drives.

SCM 025-108 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. The SCM 025-108 M2 covers the entire displacement range 1.55-6.59 cu in/rev. at a maximum pressure of 5800 psi. The motors well dimensioned, double tapered roller bearings permit high shaft loads and lead to excellent speed characteristics. The high level of reliability is based on the choice of materials, hardening methods, surface structures and the quality assured manufacturing process.

Data concerning RPM are based on maximum premitted peripheral velocity of the tapered roller bearing.
Max intermittent power data may vary dependent on application. For further information please contact Sunfab.
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.
