Bearing size chart (PDF)

A chart made by MR with the boundary dimensions of 1,887 basic designations in 79 series: deep groove, self-aligning and angular contact ball bearings, cylindrical, spherical and tapered roller bearings, and thrust bearings. Each designation in the PDF links to its SKF product page or to its series table on this site.

These are boundary dimensions according to ISO 15, ISO 355 and ISO 104, the same in every brand for the same basic designation. The exact variant (seals, internal clearance, cage) is quoted by part number.
