Overview
The SKF 22236 CCK/C3W33 is a spherical roller bearing engineered for demanding industrial environments where heavy radial and axial loads must be sustained. This double-row design with tapered 1:12 bore delivers the durability and precision SKF is known for, combining self-aligning capability with robust load capacity.
Key Features
- Double-row construction enhances radial and axial load capacity
- 1:12 tapered bore design for secure mounting with conical sleeve
- Self-aligning roller geometry accommodates shaft misalignment and deflection
- Steel cage and guide ring minimize friction and maintain optimal roller alignment
- Maximum operating speed of 2600 rpm supports variable-speed applications
- C3 internal clearance ensures proper fit in typical operating conditions
Technical Specifications
The SKF 22236 CCK/C3W33 meets exacting tolerances and load ratings essential for heavy machinery. Its symmetrical rollers self-adjust for uniform load distribution, reducing stress concentration at roller ends and extending service life in continuous-duty applications.
Typical Applications
- Pulp and paper mill equipment rollers and presses
- Wind turbine main shaft bearings
- Heavy mining and quarrying machinery
- Continuous casting operations
- Vibratory and high-impact industrial equipment
- Gearboxes and industrial reducers
