† page 35 Values: ISO 199 (table 10, page 46)
Permissible The permissible misalignment is reduced as the load increases.
misalignment Guideline values for rotating shaft applications: table 1.
Whether these values can be fully exploited depends on the design of the bearing arrangement, the external
sealing design, etc.
For applications with a rotating housing washer, or where the direction of misalignment is not constant relative
to the housing washer, additional sliding may occur in the bearing and misalignment should be < 0,1°.
