SCM 012-130 SAE
12Pages

Sunfab’s SCM 012-130 SAE is a range of robust axial piston motors especially suitable for mobile hydraulics. Other advantages: SCM 012-130 SAE 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. It covers the entire displacement range 12-130 cm³ ⁄rev. at a maximum pressure of 400 bar. It features double tapered roller bearings, which permits high shaft loads and gives superb speed performance. • Smooth operation over the entire speed range • High maximum speed • Available in many different configurations of shafts and connections • High efficiency • Speed sensor available as option The high level of reliability is based on the choice of materials, hardening methods, surface structures and the quality assured manufacturing process. • Suitable for applications with high angular accelerations due to its high rotary stiffness Sunfab also offers a two-bolt flange, SAE B2 012- 034 in the SCM family. The design features double tapered roller bearings, which permits high shaft loads and gives superb speed performance. Working pressure max intermittent max continuous Revolutions max intermittent max continuous min continuous Power max intermittent max continuous Starting torque theoretical value Mass moment of inertia (x 10-3) Weight 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.

General instructions Choice of shaft seal Temp. Max. housing pressure MPa at rpm Code according to page 2, Versions, main data Factors affecting the choice of shaft seal include the hydraulic motor housing pressure and the drainage oil temperature. The drainage oil should have a maximum temperature of 75 °C with a Nitrile shaft seal and 90 °C with a Viton shaft seal. These temperatures The housing pressure must be equal to or greater than the external pressure on the shaft seal. Shaft loads The life of the motor is highly dependent on the bearing life. The bearings are affected by operating...

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. Counter pressure valve Cooling/flushing of the motor housing can be needed to keep the drain flow temperature at an acceptable level. Suggested flow: 012-034 040-064 084-130 Counter pressure valve 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...

The motor housing should be filled with oil to at least 50% before starting. Recommended oil velocity in pressure line max. 7 m/sec 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. Cleanliness according to ISO norm 4406, code 16/13. Additional technical data Hydraulic fluids Noise levels and bearing life calculations available on request. Please contact Sunfab! High performance oils meeting ISO specifications – such as HM, DIN 51524-2 HLP, or better – must be used. A min. viscosity...
