In 20 of the 22 sizes the basic designation is also listed on its own, without a suffix. The most frequent SKF suffixes, with the number of sizes they appear in: VA983 (6), B (5), CL7C (4), J2 (2), and BJ2 (1). The suffix defines the variant (sealing, cage, internal clearance or other options): to request a quote, send us the full part number marked on the bearing, the box or the drawing.
How to read the part number: 323 gives the bearing type and the dimension series; for the same bore, each series has a different outside diameter and width. What follows is the bore code: from 04 upwards, multiplying by 5 gives the bore in millimetres (in the 32306, 06 × 5 = 30 mm); 00, 01, 02 and 03 stand for 10, 12, 15 and 17 mm.
The table gives the boundary dimensions of each basic designation according to ISO 355, in millimetres: d is the bore, D the outside diameter and T the total width. These are standardised dimensions: the same basic designation has the same dimensions in every brand. Where a dash appears, the dimension has not been validated yet: we confirm it when we quote.
If the part number on the bearing can no longer be read, measure the bore, the outside diameter and the total width, and find the matching row: with that size and the variant you need, we will quote it.
