Permissible speed

For polymer thrust ball bearings, the limiting speed (→ product table) is to be used as the determining factor to estimate the permissible speed.
The permissible speed depends on the applied load and the operating temperature. When both values are known, the adjustment factor for speed fn can be calculated using

 
where
fn
adjustment factor for speed
P
applied bearing load [kN]
fT
adjustment factor for temperature (diagram 1)
Climdynamic load limit [kN] (→ product table)

Starting with the calculated adjustment factor for speed fn from the y-axis (diagram 1), the percentage of the limiting speed can be determined and the permissible speed can be calculated.
