CARB toroidal roller bearings

CARB toroidal roller bearings have one row of long, slightly barrel-shaped symmetrical rollers and torus-shaped raceway profiles . They are non-locating bearings and accommodate exclusively radial loads. CARB bearings are often used to replace the non-locating spherical roller bearing in a locating/non-locating bearing arrangement.Depending on their series and size the following open CARB toroidal roller bearings are available as standard: bearings with a roller centred cage bearings with an inner ring centred cage ()full complement bearings with a retaining ring.The load carrying capacity of full complement CARB bearings is considerably higher than that of same-sized bearings with a cage.


The CARB bearing is a single row roller bearing with relatively long, slightly crowned rollers. The inner and outer ring raceways are correspondingly concave and symmetrical . The outer ring raceway geometry is based on a torus, hence the term toroidal roller bearing. The SKF toroidal roller bearing is designed as a non-locating bearing.
