As we have discussed, bearings can have many different design configurations. To help navigate these and easily identify the bearing you require, they usually have a code that relates to the bearing type, size and even material.
Bearing manufacturers can create their own codes or prefixes, please note these may differ depending on the brand, so it is always recommended to check the details from the specific manufacturer.
Bearing Code Example - 6 2 02 2RS
Let's break down this example by each part:
(6) 2 02 2RS - The first number refers to the Bearing Type. 6 = Single row deep groove ball bearing.
6 (2) 02 2RS - The next digit donates the Bearing Series or durabilityof the bearing. 2 = Light
6 2 (02) 2RS - These numbers relate to the Bore Size. 02 = 15mm
6 2 02 (2RS) - Finally the suffix contains any further details around the bearing such as seals or shields. 2RS = Both Sides Sealed.
A bearing with the code 62022RS is a Single row deep groove ball bearing with light toughness, bore size of 15mm and has both sides sealed.
Despite the slight differences between manufacturers, most bearings will follow this structure for their codes. So you can use the information below to determine the bearing you have or require.
