CARB toroidal roller bearings

CARB toroidal roller bearings

CARB toroidal roller bearing

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.

Bearing features

Accommodate misalignment

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).

Low friction

Self-guiding rollers keep friction and frictional heat at low levels (fig. 6).

Improved wear resistance

All CARB bearings are upgraded SKF Explorer bearings.

Low noise

CARB bearings can reduce noise and vibration levels, for example, in paper machines and fans.

Long bearing system life

fig. 7

CARB bearings provide benefits in self-aligning bearing arrangements (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.
