Bent Axis Piston Motors SCM Series
SCM 010 - 130 ISO MotorsGeneral Information
The SCM-ISO series motor is a range of robust axial piston motors expecially suitable for mobile hydraulics.The SCM-ISO series motor 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-ISO series motors covers the entire displacement range 10 - 130 cm3/n. at a maximum working pressureof 40 MPa.The SCM-ISO series motors is well dimensioned, double tapered roller bearings permit high shaft loads and lead toexcellent speed characteristics.The SCM-ISO high level of reliability is based on the choice of materials, hardening methods, surface structures andthe quality assured manufacturing process.
Data concerning the speed are based on the maximum permitted peripheral velocity for the tapered rolle bearings.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.

Bent Axis Piston Motors SCM Series
SCM 034 - 108 M2 MotorsGeneral Information
The SCM-M2 series motor is a range of robust axial piston motors expecially suitable for winch, slewing, wheel andtrack drives.The SCM-M2 series motor is of the bent-axis type with spherical pistons. The design results in a compact motor withfew moving parts, high starting torque and high reliability.The SCM-M2 series motors covers the entire displacement range 47- 108 cm3/n. at a maximum working pressureof 40 MPa.The SCM-M2 series motors is well dimensioned, double tapered roller bearings permit high shaft loads and lead toexcellent speed characteristics.The SCM-M2 high level of reliability is based on the choice of materials, hardening methods, surface structures andthe quality assured manufacturing process.
Data concerning the speed are based on the maximum permitted peripheral velocity for the tapered roller bearings.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.

SCM 034 - 108 M2 MotorsGeneral Instructions
Shaft loadsThe lifeof the motor ishighly dependent on thebearing life.
The bearings are affectedby operation conditionssuch as speed, pressure,oil viscosity and filtration.External load on the shaft,as well as its size, directionand location also affect thebearing life.
For calculation of bearinglife in special applications,please contact our Tech Dpt.
InstallationThe motor housing shouldbe filled with oil to at least50% before starting. Thedrainage pipe should beconnected to topmostdrainage outlet.
The other end of the pipeshould be connectedto the oil tank at a pointbelow the oil level.
PipingRecommended oil velocityin pressure line max.7 m/sec.
FilteringCleanliness according toISO norm 4406, code 16/13.
