Overview
The SKF 22226 CCKJ/C3/W33 is a double-row spherical roller bearing featuring a tapered bore design for secure mounting on tapered sleeves. This bearing combines optimized roller geometry with durable materials to deliver high load-carrying capacity and self-alignment capabilities across demanding industrial applications including mining, heavy machinery, and mechanical power transmission. The tapered bore design—indicated by the “K” designation in the model number—enables reliable mounting without force-fit concerns.
Key Features
- Double-row spherical roller design for enhanced radial and axial load capacity
- Tapered bore allows self-aligning adjustment during installation
- Self-alignment capability reduces stress from shaft misalignment and extends bearing life
- Robust construction provides superior rigidity and stability in high-load environments
- Optimized lubrication options minimize maintenance requirements and downtime
- C3 radial clearance class provides optimal performance in typical industrial applications
