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.

The smaller RGP10k test bench is optimized for our projects on machine learning in tribology. Numerous sensor sizes provide the basis for AI-supported investigations of radial plain bearings.

There is also an adaptation for this test stand to examine original ball joints in a pivoting manner.
