They are all the same bearing type: tapered roller bearings (8 part numbers, series 303 and 313).

5 of the 8 part numbers are the basic designation alone, without a suffix. The most frequent suffixes, with the number of part numbers they appear in: A (2) and VA983 (1).

These are boundary dimensions according to ISO 355, in millimetres: d is the bore, D the outside diameter and T the total width (tapered bearings).

Two bearings with the same size are not necessarily the same bearing: the type, the seals or shields, the internal clearance, the cage and the load rating depend on the designation, the suffix and the brand. That is why we quote by part number: send us the full part number shown on the bearing, the box or the drawing, or the size together with the variant you need.

If the part number can no longer be read, measure the bore, the outside diameter and the width, and look the size up in the bearings-by-size index: each size has its own page with all its part numbers.
