iglide® PRT - Application Examples

3Lifetime calculation, configuration and more ➤ www.igus.com/PRT

In this machine tool control panel, an iglide® plastic slewing ring bearing is used due to its freedom from external lubrication and maintenance.

The self-lubricating iglide® PRT slewing ring bearing masters this job brilliantly, is lighter and in terms of purchasing is cheaper than a comparable metal rotary connector.

A light and self-lubricating iglide® PRT slewing ring bearing is used in a self-rotating light, as found in discos for example.

Self-lubricating and maintenance-free plastic slewing ring bearings for moving the control panel. The low coefficients of friction ensure low actuating force during pivoting.

The iglide® PRT-01-100 slewing ring bearing is used in an automatic welding plant in this application. It enables pivoting in the horizontal plane of the clamping device.

iglide® PRT-01-60 is used here in a handling/transport system for semiconductor carriers. Through a cylinder control, the PRT plastic slewing ring bearing provides a deflection at the end of the system’s track.

All load values assume the PRT is assembled with socket head screws (strength class 8.8) on the outside pitch circle diameter. For the assembly (using strength class 8.8 screws) of the PRT, the screws have to be inserted to a minimum thread depth of 2 x d in every hole location in the outer ring. All data can be used for both lateral and horizontal assembly (including overhead installation).
