FAQ

The 'K' indicates a tapered bore with a standard taper of 1:12, designed for mounting on a tapered shaft or an adapter sleeve. The 'C3' denotes a radial internal clearance that is greater than normal, which is essential for applications with high temperatures or tight fits that could reduce clearance during operation.

Yes, this bearing is suitable for both grease and oil lubrication. The 'W33' suffix indicates it has a lubrication groove and three holes in the outer ring, which facilitates efficient relubrication directly to the rolling elements, a feature beneficial for both lubrication methods.

Spherical roller bearings like the 22213 are designed to handle very high radial loads and moderate to high axial loads in both directions. The internal geometry with two rows of symmetrical rollers allows them to accommodate heavy combined loads effectively.
