Abstract

A very compact play-free bearing unit includes a bearing that runs without play while having a reasonably large play when assembling and during disassembly of the bearing unit from its axle. The bearing unit uses three bearings, one of which is mobile, and thanks to a preloading mechanism the play is removed when loaded. Thanks to an amplification lever, the preloading unit is able to function either with a pneumatic actuator or with a hydraulic actuator.
