Overview
The SKF 22308 CC/C3W33 is a precision-engineered spherical roller bearing built for demanding industrial applications. This double-row design features two rows of symmetrical rollers with a 1:1 cylindrical bore and C3 radial internal clearance to accommodate dimensional inaccuracies in housing and shaft alignment. The bearing’s robust construction delivers reliable performance in heavy-load, moderate-speed, and misalignment-prone environments.
Key Features
- Double-Row Design: Two rows of spherical rollers enhance load-carrying capacity and stability while accommodating shaft-to-housing misalignment.
- C3 Internal Clearance: Optimized for typical industrial fits and accommodates thermal growth in operating conditions.
- High Load Capacity: Capable of supporting elevated radial and axial loads simultaneously, suitable for heavy-duty machinery.
- Misalignment Tolerance: Spherical roller geometry permits angular misalignment between shaft and housing, extending bearing life.
- Durable Materials & Lubrication: Optimized roller geometry and effective grease retention support extended operating intervals in mining, heavy machinery, and mechanical transmission applications.
