6) SUGGESTIONS
a)
MISALIGNMENT
Thrust ball bearings with flat housing washers do not permit
any angular misalignment between shaft and housing, nor any
errors of alignment between the support surfaces in the housing
and the shaft.
b)
MINIMUM AXIAL LOAD
We suggest the minimum axial load to be applied in such cases
can be estimated from: Famin = A( n/ 1000)2 [ N] 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 must not exceed 2000C.
