Roller bearings are bearings in which two components that move relative to each other – the so-called inner ring and outer ring – are separated by rolling elements.
Barrel roller bearings are particularly suitable for designs that require high radial load-carrying capacity and compensation for alignment errors. They are especially appropriate for applications with high radial shock-type loads. The bearings cannot be dismantled and, with normal loads and a circumferential inner ring, can only be displaced from the centre position by a maximum of 4°.
