Ball Bearings - 20mm Bore

Deep Groove Ball Bearings

To identify your bearing requirements more precisely, it helps to have the following information to hand:

  • Marks and numbers which are normally to be found somewhere on the bearings.
  • 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:

Prefix Suffix
S = Stainless Steel RS = Single Rubber Seal
F = Flanged 2RS = 2 Rubber Seals
MR = Metric Z = Single Metal Shield
MF = Metric Flanged ZZ= 2 Metal Shields
R = Inch  

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