Spherical roller bearings are rolling-element bearings designed to support heavy radial loads and moderate axial loads in both directions.

They are self-aligning, meaning they can tolerate misalignment between the shaft and housing without reducing performance.

Key Features

• Accepts high radial loads and some axial load, in both directions
• Self-aligning: can tolerate shaft/housing misalignment (e.g. due to deflection)
• EA: suffix indicates an enhanced capacity version (higher load rating than baseline “E” versions).
• B33: is a clearance / internal play designation (means larger than standard radial internal clearance).
• K: Tapered bore (1:12 taper) (means requires adapter sleeve or withdrawal sleeve for mounting).
• W33: Lubrication groove and holes provided in the outer ring for grease or oil supply.
