Staffa HMB Series Radial Piston Motor | Antech Hydraulics
HMB Series consists of 12 frame sizes ranging from the HMB010 at 188cc/rev through to HMHDB400 at 6800 cc/rev Output torques up to 25,250 Nm. Staffa motors are renowned for the excellent reliability. If properly maintained, not subjected to loads or stresses beyond their capability, and used with clean hydraulic oil, Staffa motors have been known to last over 25 years in service!
- Rugged, reliable, proven design.
- High volumetric and Mechanical efficiency.
- Large variety of shaft and porting options.
- Alternative displacements available
- Wide range of mounting interfaces available.
- Unique Hydrostatic balancing provides minimum wear and extended life.
Consideration should be taken upon required motor in terms of bearing service life. The factors that will determine bearing life include:
- Duty Cycle.
- Differential Pressure.
- Fluid Viscosity.
- External Radial Shaft Load.
- External Axial Shaft Load.
All staffa motors can be used in freewheeling Applications.
In all circumstances it is essential that the motor is unloaded (A and B ports connected together) and that the circuit is boosted. The required boost pressure will be dependent on the required speed and displacement conditions.
It should be noted that for HMB Series motors to achieve freewheel, large flows will have to re-circulate around the motor. This will require a large re-circulating valve and consideration of the circuit cooling as the motor will generate a large braking torque.
Therefore for these reasons we would suggest a ‘HMC’ or ‘HPC’ Motor would be a preferred option for freewheeling applications.
For more information on freewheeling application please see the HMB Series Data Sheet and refer to page 24
