Bearing Numbers Demystified

Want to buy bearings for your plant, machine, or other items? Well, the bearings are numbered, and it is important to understand these numbering. So, here will demonstrate what these numbers mean and how they are given.

Every bearing number, take the example S6001 2RS, is a combination of three crucial components as demonstrated below: (1) prefix, (2) basic number, and 93) suffix. See the image demonstration below.

Prefix: The prefix of bearing is given by the company that manufactures it.

Basic Number: The suffix of a bearing number, such as 6001 in our example above, is used to indicate the bearing type. In this case, 6001 is a deep groove ball bearing with a single row.

Suffix: This code is used to identify bearing variants that differ in one way from the current standard designs. Some common suffixes and their meaning include:

• 2 RS: Mean that the bearing has a rubber seal on two sides.
• K: Means bearing designed with a tapered bore.
• E: Means bearing with a reinforced design.
