Bearing suffix cross reference: keep the complete marking
A base designation groups possible relatives. Suffixes identify differences that can determine whether a replacement works.

What to check
Capture the whole identifier
Record manufacturer, prefix, base number and every suffix. A partial marking can omit clearance, heat stabilization, lubrication or a matched-set requirement.
Compare definitions, not letters
Different brands can use different letters for related features, or similar letters for different features. Read the original descriptions side by side.
Choose a precise reference product
Search the full part number first. Then use the base-model comparison to explore brands and select exact variants in Custom Compare. Do not silently substitute a shorter designation.
Continue with real catalogue data
Preserve the full model, source description and unknown fields when making your shortlist. This reference website does not sell bearings or certify a replacement.

Cross-reference results are candidates for verification. A shared base number or envelope is not a manufacturer-approved replacement statement.

OEM, National, Fafnir, Torrington, RHP, SNR, McGill, Dodge and other legacy-number searches need an evidenced identifier relationship, not a similar-looking model.
Read and apply →Reference basis & data limits
Manufacturer terminology is retained in the product records. Technical reference basis: JTEKT Basic Bearing Knowledge (boundary dimensions, tolerance classes and lubrication); NSK Bearing ABCs (lubrication, designations and clearance); NTN technical FAQs (closure codes and component interchange); SKF rolling-bearing selection and maintenance references.
Selection workflows and catalogue grouping are BearingScope editorial aids. Verify the current drawing and application requirements before using a candidate. Missing database information is not converted into an assumed match.
