Overview
The SKF 22324 CCK/C3W33 is a precision spherical roller bearing engineered for demanding industrial applications requiring high load capacity and misalignment tolerance. This single-row bearing features a 1:12 tapered bore with flangeless inner ring design, making it ideal for applications in gearboxes, crushers, vibrating screens, papermaking machinery, and similar equipment operating under heavy radial and axial loading conditions.
Key Features
- Self-aligning design accommodates misalignment from shaft or housing deflection
- High load-carrying capacity for heavy radial and axial loads in both directions
- Increased radial clearance (C3W33) for optimal performance in thermal expansion conditions
- Tapered 1:12 bore enables secure mounting without additional clamping
- Two stamped steel cages with guide ring center for robust stability
- Lubrication groove with three holes in outer ring for efficient lubrication distribution
- Open design—no seals, ideal for grease or oil lubrication in accessible mounting positions
