Radial plain bearing test rigs (RGP6k and RGP24k)

The two radial plain bearing test rigs can be used to realistically test original bearings made of metal and plastic.

A needle bearing inner ring or sleeve sits on the test shaft and rotates in the plain bearing bushing to be tested. The load is applied pneumatically and can be changed by software during the run. All measured variables are recorded electronically and stored and analyzed on a PC.

For the small test stand RGP6k there is an adaptation to examine original swiveling ball joints.
