Axial Piston Motors – fixed displacement, bent axis

The F1 is a fixed displacement bent axis, truck hydraulic motor that can tolerate low temperature and high temperature shocks, and high acceleration.

F11/12 is the high performance bent axis, fixed displacement heavy-duty motor series.  They can be used in numerous applications in both open and closed loop circuits.  The 40° angle between shaft and cylinder barrel allows for a very compact, lightweight motor.  The simple straightforward design with very few moving parts, make them very reliable motors.

Coloured cable ties

Ingenious use for coloured cable ties!

A 10 bank spool valve was brought into our workshop for inspection. Prior to removing the valve coloured cable ties were fitted to all inlets and outlets of the valve and machinery. The colour cable ties will greatly assist with the refitting of the valve.
