Description
SKF 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.
Applications
Here are examples of applications in which CARB toroidal roller bearings might be used:
- Industrial transmission
- Metals
- Pulp and Paper
- Mining, mineral processing and cement
- Industrial fans
- Marine
Features and benefits
- Accommodate misalignment
CARB bearings are self-aligning like spherical roller bearings or self-aligning ball bearings. - Accommodate axial displacement
CARB bearings compensate for thermal expansion of the shaft like cylindrical or needle roller bearings. - 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. - Long service life
The special roller profile prevents stress peaks at the roller ends. - Low friction
Self-guiding rollers keep friction and frictional heat at low levels. - 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
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.
