Two bearings wear test rig 

Purpose designed and built test rig for testing operational conditions and wear measurements of two sliding bearings. Originally designed for bearings lubricated by environmentally acceptable lubricants, now often used for magnetorheological liquids.

In typical case journal diameter is 30 mm and specific pressure up to 2 MPa.

The test rig was used in commercial tasks and research [1].

2 – tested bearing bush housing,
3,4 – tested bearing bush with sleeve,
5 – load ring with ball bearing,
6 – covers with sealings,
10 – two seals module,
11 – self-alignment ball bearing,
t – thermocouples
