Rotating, Torque Resisting Sliding Bush with Radial Bearing
This unit combines:
*the sliding properties of a ball bushing,
*the anti-torque of a spline shaft (the shaft is grooved to allow 4 circuits of balls to engage in it)
*the anti-friction, high load capacity & rigidity of a cross roller bearing
Mounting holes are provided in the faces of the torque resistant bush (PCD values in Column 'e') and the radial bearing (PCD values in column 'E')
This unit is designed for heavy duty applications. (NB Loads below are in kN - Kilonewtons- approx = 100's of Kilograms)
Examples of application:
Rotating Z Axis on Pick & Place Machine (3 axis machine)
Tool Changer turret on machine tool
Rotating. adavancng and retacting turret on machine tool
Spooling or winding machines
