Determine bearing size based on the static load carrying capacity.
Guideline values for static safety factor sO
Operation type | Low performance | Ball bearings | Low performance | Roller bearings | Normal performance | Ball bearings | Normal performance | Roller bearings | High performance | Ball bearings | High performance | Roller bearings |
Smooth, vibration free | 0.5 | 1 | 1 | 1.5 | 2 | 3 |
Normal | 0.5 | 1 | 1 | 1.5 | 2 | 3.5 |
Pronounced shock loads | 1.5 or more | 2.5 or more | 1.5 or more | 3 or more | 2 or more | 4 or more |
Spherical roller thrust bearings sO = 4 or more.
These values can be used for preliminary estimates only. For final selection, confirm with equipment manufacturer.
