Most bearing references now are laser stamped but these wear and rub off more quickly than the previous method, which was engraved deep in the bearing's metal.

Each bearing has an inside diameter, outside diameter and width diameter in that order. Most bearings are metric in size, but can also be imperial. On our site, each bearing shows its principal dimensions.

Once you have identified the bearing's code some bearings come complete with seals or shields. This is known as the suffix in the bearings reference. The bearing type design that you need is a single row deep groove ball bearing with the following dimensions and suffix.

And the internal clearance being C3 means that the bearing has room for expansion if needed between the races of the bearing, whilst holding the outer ring and moving the inner ring in a radial movement you will detect a little amount of play between the 2 rings. We must find out 3 numerical values that are those that physically define the reference of a bearing and whose designation is recognized internationally in all catalogs and reference tables with the letters d x D x B being:.

The caliper or Pie de Rey in Spanish is a measuring instrument that allows you to find out internal, external diameters and depths in both mm and inches. If you have to proceed with a millimeter rule, the process will not be as precise but it will be equally valid.

After disassembling our skate, skate or bicycle we can find in the hand with a bearing that we have decided to replace but whose reference or standard designation does not appear anywhere.

Wear, dirt or poor condition of the bearing can make such information illegible. That is when we have to turn to a specialized mechanic or find out what the dimensions of our bearing are in order to buy it.
