Axial piston fixed motor A2FM has extremely high adaptability and flexibility. It is suitable for both open and closed circuit applications. The motor has the characteristics of compact design, high overall efficiency, and economical and practical application.
■Shaft seal…Permissible pressure loading
☑The service life of the shaft seal is influenced by the speed of the axial piston unit and the case drain pressure (case pressure).
☑The mean differential pressure of 2 bar between the case and the ambient pressure may not be enduringly exceeded at normal operating temperature.
☑ For a higher differential pressure at reduced speed, see diagram. Momentary pressure spikes (t < 0.1 s) of up to 10 bar are permitted. The service life of the shaft seal decreases with an increase in the frequency of pressure spikes.
☑The case pressure must be equal to or higher than the ambient pressure.
■Temperature range
☑The FKM shaft seal may be used for case drain temperatures from -25 °C to +115 °C
☑For application cases below -25 °C, an NBR shaft seal is required (permissible temperature range -40 °C to +90 °C). State NBR shaft seal in plain text when ordering. Please contact us.
■Direction of flow
| Direction of rotation, viewed on drive shaft | Direction of flow |
| clockwise (R) | A→B |
| counter-clockwise (L) | B→A |
■ Speed range
☑ No limit to minimum speed nmin. If uniformity of motion is required, speed nmin must not be less than 50 rpm. See table of values for maximum speed.
■ Long-life bearing
☑ Sizes 250～500
☑ For long service life and use with HF hydraulic fluids. Identical external dimensions as motor with standard bearings. Subsequent conversion to long-life bearings is possible.
☑Bearing and case flushing via port U is recommended.
