CARB Toroidal Roller Bearings: Self-Aligning Bearings for High Load and Long Service Life
CARB toroidal roller bearings are unique: as well as accommodating misalignment without increased stress levels, they also provide frictionless axial movement within the bearing in the non-locating position in self-aligning bearing arrangements. They can accommodate higher load levels and provide significantly extended service life.
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. 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.
Applications
Here are examples of applications in which CARB toroidal roller bearings might be used:
