CARB toroidal roller bearings
CARB toroidal roller bearings have one row of long, slightly barrel-shaped symmetrical rollers and torus-shaped raceway profiles (fig. 1). 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.
CARB bearings are self-aligning like spherical roller bearings or self-aligning ball bearings (fig. 2).
Accommodate axial displacement
CARB bearings compensate for thermal expansion of the shaft like cylindrical or needle roller bearings (fig. 3).
Wide assortment of dimension series
CARB bearings are available with the same boundary dimensions as corresponding spherical roller bearings, self-aligning ball bearings, cylindrical roller bearings and needle roller bearings (fig. 4)
Long service life
The special roller profile prevents stress peaks at the roller ends (fig. 5).
Self-guiding rollers keep friction and frictional heat at low levels (fig. 6).
Improved wear resistance
The complete standard assortment is of the upgraded SKF Explorer class.
CARB bearings can reduce noise and vibration levels, for example, in paper machines and fans.
Long bearing system life
fig. 7). With a CARB bearing in the non-locating position, there are no internally induced axial forces, which results in multiple benefits:
- Less load extends the service life.
- The bearings run cooler, the lubricant lasts longer and maintenance intervals can be extended.
- Noise and vibration levels can be reduced.
