How to read the part number: 514 gives the bearing type and the dimension series; for the same bore, each series has a different outside diameter and height. What follows is the bore code: from 04 upwards, multiplying by 5 gives the bore in millimetres (in the 51406, 06 × 5 = 30 mm).

The table gives the boundary dimensions of each basic designation according to ISO 104, in millimetres: d is the bore, D the outside diameter and H the height. 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 height, and find the matching row: with that size and the variant you need, we will quote it.
