- 10Bore
- Bore 50 mm (10 × 5).
- EJSuffix
- TIMKEN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
21310 is the standard ISO basic designation, which sets the bearing type, series and bore.

When shaft and housing alignment cannot be held perfectly, Timken EJ series spherical roller bearings are built to handle combined radial and axial loads. Their two rows of rollers let the bearing compensate for angular misalignment, which suits equipment that flexes or is mounted with some deviation. Typical uses include industrial machinery, conveyors, mills and process equipment.
The EJ suffix tells you about internal design details, including cage type. The base number before it indicates size and load capacity. Models such as 21305EJ, 21306EJ and 21307EJ share the suffix but differ in dimensions, so the full code matters when you order a replacement.
You will find these bearings in cement, mining, steel, paper and food plants, on conveyors, mills, crushers, industrial fans and continuous process lines. In these settings, loads are heavy and contamination is common, so the bearing needs to be robust.
Selection depends on radial and axial load, operating speed and the working environment. Sealing and lubrication deserve attention: match the seal to dust or moisture exposure, and keep lubrication adequate. Align the bearing correctly during mounting to avoid extra stress and early failure.
Bearings from other brands can be interchangeable when dimensions and load capacity line up. Timken is a recognized name in the market, and we can help you find a suitable equivalent for your equipment. Always check the technical specifications before swapping one manufacturer's bearing for another.
