Bearing Size Charts
A useful bearing size reference begins with the complete designation and boundary dimensions. Record the bore diameter (d), outside diameter (D) and width (B), using millimetres for the initial enquiry. Some bearing types use different dimension symbols, so retain the original drawing when available.
Prepare a dimension reference
- Measure the removed bearing rather than estimating from a photograph.
- Include the full marking, seal arrangement and any special ring features.
- State whether a width refers to one component or an assembled unit.
- Attach a dimensioned drawing for unusual or custom parts.
Search by size
Use a query such as 25 × 52 × 15 mm in the bearing search. Matching dimensions help identify candidates; they do not by themselves establish interchangeability.

Keep the configuration in the enquiry
Two references with the same boundary dimensions may differ in seals, clearance, cage or intended arrangement. Keep the complete designation beside the dimensions when requesting a quotation.
Discuss your bearing requirement
Send the complete designation, quantity, equipment details and operating conditions. We will review the reference and confirm the sourcing option before quotation.
