They are self-aligning and accommodate misalignment and shaft deflections, with virtually no increase in friction or temperature. The design includes features to facilitate relubrication. The bearings can be used in a modular system, including housings, sleeves and nuts.

Bearings can differ in very slight ways, and so there are a lot of codes to decipher what a bearing specifically does just by its product code. The PDF below is taken from the SKF bearing catalog here and can help you to find the right bearing for you.
