CARB toroidal roller bearingCARB toroidal roller bearings combine the self-aligning capability of spherical roller bearings with the axial displacement ability of cylindrical roller bearings. CARB bearings can also have the compact cross section and high load carrying capacity normally associated with needle roller bearings.
CARB bearings are intended exclusively as non-locating bearings. They can simplify the bearing arrangement design for shafts that are subjected to thermal expansion/contraction because axial displacement is accommodated within the bearing, virtually without friction. Bearing systems consisting of a spherical roller bearing in the locating position and a CARB bearing in the non-locating positionprovide a space and weight-saving bearing system with a low cost of ownership. CARB bearings can reduce noise and vibration levels, e.g. in paper machines and fans. CARB bearings are single row bearings with long, slightly barrel-shaped symmetrical rollers.
The outer ring has a torus-shaped raceway with a profile radius extending beyond the centre of the bearing. The inner ring raceway is shaped accordingly. The rollers of CARB bearings are self-guiding, i.e. they always adopt the position where the load is favourably distributed over the roller length, irrespective of whether the bearing rings are misaligned or axially displaced. The ability to distribute loads favourably keeps the friction and friction-generated heat at low level. Lower operating temperature extends the service life of the lubricant and the bearing. .
