Type

Data concerning RPM are based on maximum premitted periph-eral velocity of the tapered roller bearing.

Sunfab SCM is a range of robust axial piston motors especially suitable for mo-bile hydraulics.

Sunfab SCM is of the bent-axis type with spherical pis-tons. The design results in a compact motor with few mo-ving parts, high starting tor-que and high reliability.

Motor SCM 012–130 SAE

The SCM covers the entire displacement range 12-130 cm3/rev at a maximum wor-king pressure of 40 MPa.

SUNFAB SCM SAE 012-034 features double tapered roller bearings, which permitshigh shaft loads and gives su-perb speed performance.

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.

3202 GB

SUNFAB SCM SAE 040- 130 combines a tapered roller bearing and a radial bearing for high radial load tolerance and long life time.

SUNFAB SCM’s high level of reliability is based on the choice of materials, hardening methods, surface structures and the quality assured ma-nufacturing process.

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.

Shaft loads

The life of the motor is highly dependent on thebearing life. The bearings are affected by operation conditions such as speed, pressure, oil viscosity and filtration.

Piping

Recommended oil velocity in pressure line max. 7 m/sec

Filtering

Cleanliness according to ISO norm 4406, code16/13.

External load on the shaft, as well as its size, direction and lo-cation also affect the bearing life. For calculation of bearing life in special applications, please contact Sunfab Hydraulics.

Q

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 tempe-rature 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. RPM 012-034 2-8 ≥ 2800 040-064 4-10 ≥ 2500 084-130 6-12 ≥ 2200

Installation

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 compen-sated for by a counter pressure valve.The tank line is connected to the highest point as in the figure.
