Selecting Process
To select a ball bearing part number and specification properly, it is necessary to fully understand the required performance of the ball bearings by confirming the structures, dimensions, environment, and conditions of each application using the ball bearing. The process of selecting a ball bearings is shown below.

■Application conditions, environment and required performance
- Equipment structure and functions
- Operating environment
(temperature, humidity, vibration, dust, etc.) - Load
- Dimensions and materials of shaft and housing
- Rotational speed, rotation precision, rotating ring
- Torque
- Sound
- Life
- Restricted substances
- Special environmental conditions

■Selecting a type
- Bearing dimensions

■Tolerance and class


■Selecting a lubricant
- Lubricants
Application conditions table: Use as a reference when determining the bearing type and specifications.
