6) SUGGESTIONS

a) MISALIGNMENT

Cylindrical roller thrust bearings do not permit any angular misalignment between shaft and housing nor any errors of alignment between the support surfaces in the housing and on the shaft.

b) MINIMUM AXIAL LOAD

We suggest the minimum axial load to be applied, in such cases can be estimated from Fa min = A(n/1000)2, [KN]where: n = speed, [r/min] A= minimum load factor (see bearing tables)

c) RUNNING TEMPERATURES The limit operation temperature depends on the oil used at the bearing lubrication and not exceed 2000C.
