Ball bearings are used to work with low friction at different speeds and high loads where the speed is frequently changing. Ball bearings have a low starting resistance which enable a high number of revolutions showing a very low temperature rise.

Explanation of how the product code works

Example:

6203 - Basis designation of the series

2RS - Suffix sealing (number and type of seal and material properties)

C3 - Suffix features (tolerance, clearance, preload)

Suffix Meanings:

2 RS - Bearing with rubber seal on both sides. RS provides a better seal but more rolling friction than 2Z.

RS - Bearing with rubber seal on one side, one side open

2 Z / ZZ - Bearing with a metal seal on both sides

Z - Bearing with a metal seal on one side, one side open

E - Reinforced Design

P2 - Highest precision

K - Bearing with taper bore

P2 - Highest precision

C Codes:

C2 - Less clearance than normal

C0 of CN- The standard for applications where the normally recommended fits, and under normal operating conditions, leave the correct clearance. The C0 code is not indicated in the bearing

C3 - Clearance greater than C0 (has room for expansion)

C4 - Clearance greater than C2

C5 - Clearance greater than C4
