Enter the bore diameter your shaft needs (and outer diameter, width or seal type if you know them) — this ranks our currently-published deep groove ball, cylindrical roller, spherical roller and tapered roller bearings by how well each one actually matches. A bore or outer-diameter mismatch is excluded outright, never shown as a "close" fit — a bearing swap is a physical fit, not an approximation.
Frequently asked questions
Does a high match percentage guarantee the bearing will fit?
A bore or outer-diameter mismatch is excluded from the results entirely, not shown at a lower score — those are physical fit requirements, not preferences. A close-but-not-exact width still shows up, ranked lower and labelled why. Always confirm the full dimensions against the datasheet before ordering.
What bearing types are covered?
Deep groove ball, cylindrical roller, spherical roller and tapered roller bearings with published bore, outer diameter, width or seal-type data. Not finding what you need? Email orderdesk@kkmsolutions.com with the size and we will source it per-order.
How is this different from the Bearing Interchange tool?
Bearing Interchange tells you the equivalent designation for a bearing you already have, across SKF/FAG/NSK/NTN/Koyo. This tool instead searches by the dimensions and specs you need — bore, outer diameter, width, seal type — and ranks our currently-published bearings against them.
