Part-2 How to select the right bearing for your application?

2019-08-29

Rolling element bearings are available in a variety of types, configurations, and sizes. When selecting the correct bearing for your application, it is important to take these factors below into consideration.

 Bearing dimensions

1) Design life of components to house bearings

2) Dynamic/static equivalent load conditions

3) Safety factor

4) Allowable speed

5) Allowable axial load

6) Allowable space

4. Bearing tolerances

1) Shaft run-out tolerances

2) Rotational speed

3) Torque fluctuation

 Bearing’s internal clearance

1) Material and shape of shaft and housing

2) Fit

3) Temperature differential between inner/outer rings

4) Allowable misalignment of inner/outer rings

5) Load (magnitude, nature)

6) Amount of preload

7) Rotational speed

 Cage type and material

1) Rotational speed

2) Noise level

3) Vibration and shock load

4) Momentary load

5) Lubrication type and method

 Lubricant, lubrication method, sealing method

1) Operating temperature

2) Rotational speed

3) Lubrication type and method

4) Sealing method

5) Maintenance and inspection

Special bearing specifications

1) Operating environment (high/low temperature, vacuum, pharmaceutical, etc.)

2) Requirement for high reliability
