Overview
The SKF 22226 CCK/C3W33 is a precision double-row spherical roller bearing designed for demanding industrial applications. This bearing combines advanced roller geometry, durable materials, and optimized lubrication paths to deliver reliable performance in high-load environments. The SKF 22226 CCK/C3W33 incorporates a tapered bore with C3 clearance fit and W33 oil grooves on the outer raceway, making it suitable for machinery requiring superior radial and axial load capacity with inherent misalignment compensation.
Key Features
- Double Row Design: Two rows of spherical rollers enhance load-carrying capacity and provide exceptional stability under heavy loads.
- Misalignment Accommodation: Spherical geometry allows the bearing to tolerate angular misalignment between shaft and housing, extending bearing life in challenging installations.
- Tapered Bore (C3): C3 internal clearance combined with tapered bore design reduces preload stresses and improves bearing performance in high-speed applications.
- W33 Oil Grooves: Outer raceway grooves facilitate controlled lubrication distribution, extending service intervals in oil-lubricated systems.
- Robust Construction: Premium materials and precision manufacturing ensure durability in mining, cement mills, crushers, and gearboxes.
