TORQUE RESISTANT BUSH WITH RADIAL BEARING:

PDF Catalogue of Linear Bearings

This unit is designed for heavy duty applications and 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 low friction, high load capacity & rigidity of a cross roller bearing

Mounting holes are provided in the faces of the torque resistant bush (e) and the radial bearing (E).

Typical applications:
- Rotating Z Axis on Pick & Place Machine (3 axis machine)
- Tool Changer turret on machine tool
- Rotating, advancing and retacting turret on machine tool
- Spooling or winding machines
