• Inside dia. (I.D.) x outside dia. (O.D.) x width (W).
  (bearing dimensions are normally presented in this format.)

Most bearings, especially for industrial applications follow an internationally recognised bearing identification system. In some cases, the bearing will have a prefix, followed by a group of numbers, followed by a suffix. Some of the common prefixes and suffixes are mentioned below:

Except for "S", all bearings are made from ball bearing chrome steel. All "S" prefix bearings are stainless steel.
