Motor SCM 012-130
ISO
Sunfab SCM’s high level of reliability is based on the choice of materials, hardening methods, surface structures and the quality Sunfab SCM is of the bent- Sunfab SCM’s well dimen- assured manufacturing sioned, double tapered axis type with spherical process. pistons. The design results roller bearings permit high shaft loads and lead to in a compact motor with excellent speed characterfew moving parts, high istics. starting torque and high reliability. Sunfab SCM is a range of robust axial piston motors especially suitable for mobile hydraulics.
Type
The SCM covers the entire displacement range 12130 cm3/rev at a maximum working pressure of 40 MPa.

Data concerning RPM are based on maximum premitted 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.

General instructions Shaft loads
Optimal force direction of radial load
The life of the motor is highly dependent on the bearing life.
For calculation of bearing life in special applications, please contact Sunfab Hydraulics.

B
Pressure Anticlockwise rotation
Pressure Clockwise rotation
Bearing life (h)
The bearings are affected by operation conditions such as speed, pressure, oil viscosity and filtration. External load on the shaft, as well as its size, direction and location also affect the bearing life.
Radial load (N)
Installation The motor housing should be filled with oil to at least 50% before starting. The drainage pipe should be connected to topmost drainage outlet. The other end of the pipe should be connected to the oil tank at a point below the oil level.
Piping Recommended oil velocity in pressure line max. 7 m/sec.
Filtrering Cleanliness according to ISO norm 4406, code 16/13.

F
Temperatures/Housing cooling
Q
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.

Flushing valve
Housing flushing can be built up with the help of a flushing valve or taken directly from the return line. When the return pressure is too low this is compensated for by a counter pressure valve. The tank line is connected to the highest point as in the figure.

Simplified circuits
Hydraulic fluids High performance oils meeting ISO specifications – such as HM, DIN 51524-2HLP, or better – must be used. A min. viscosity of 10 cSt is required to keep the lubrication at a safe level. The ideal viscosity is 20 - 40 cSt.
