What is an SKF CARB bearing?

Before the introduction of the SKF CARB Bearing, or toroidal roller bearing, almost every bearing arrangement was a compromise, due to ever present misalignment and axial displacement. Combining the self-aligning properties of the spherical roller bearing with the ability to accommodate axial displacement like a cylindrical or needle roller bearing, the SKF CARB toroidal roller bearing is now a proven and effective bearing solution for non-locating bearing positions.

CARB bearings can also have a compact cross section in conjunction with the high load carrying capacity normally associated with needle roller bearings.

The CARB bearing has the following benefits:

• Reduced maintenance
• High operation reliability
• Long service life
• High load carrying capacity
• Lower operating costs
• Compact design
• Enhanced performance
• High power density

Typical industrial fan reference stories

• Every year a critical fan showed extremely high vibration levels due to bearing failures in the drive side of the blower. The CARB/spherical roller bearing self-aligning solution delivered real benefits, increasing MTBF from 1 to 5 years.
• A malting plant experienced imbalance problems and repeated failures of the locating bearing in a fan with a vertical shaft. The non-locating position was upgraded to CARB with exceptional results.
• A global producer of large electric motors used CARB on a multi splined shaft. Due to temperature gradients, significant sliding occurred between the non-locating spherical roller bearing and the housing. The introduction of CARB eliminated this issue.
