SKF 21307 CC/C3 Spherical Roller Bearing - Engineered for Precision and Durability

bearing Spherical roller bearing

Spherical roller bearings can accommodate heavy loads in both directions. They are self-aligning and accommodate misalignment and shaft deflections, with virtually no increase in friction or temperature. They can be used in a modular system, including housings, sleeves and nuts.

Accommodate misalignment

High load carrying capacity

Low friction and long service life

Increased wear resistance

Installation Method and Usage Precautions of Bearings

The SKF 21307 CC/C3 spherical roller bearing is a high-capacity bearing designed for applications that demand both radial and axial load support. This bearing is self-aligning, which allows it to accommodate misalignment and shaft deflections with minimal increase in friction or temperature. The CC/C3 designation indicates a close clearance, which is beneficial for reducing noise and vibration, and enhancing the bearing's performance. Here are the detailed specifications of this robust bearing:
