Speed correction factors

The speeds listed in the tables are attainable speeds for a single spring-preloaded bearing operating under normal conditions such as

• Good heat dissipation
• Low external load
• Rotating inner ring
• Oil-air or oil-mist lubrication
• High dimensional accuracy of bearing and associated components
• Alignment of associated components
• Good balancing of the rotating parts

If the operating conditions deviate from the conditions mentioned, correction factors must be taken into account.
Correction factors and speeds values are only for guidance.

Permissible speed = speed value · f_n1 · f_n2 · f_n3 · f_n4 · f_n5
