Alignment Fig. 8
When mounting SKF Food Line ball bearing α
units it is important for the performance and
longevity of the bearing that any misalign-
ment is kept within acceptable limits (fig. 8)
In this regard, the sphered nature of the
bearing outer ring and the housing bore can
accommodate some static misalignment
Static, as illustrated above, refers to any
initial misalignment between housing and
shaft/bearing inner ring arising from
mounting errors
For the fully sealed units this is limited, by
the back seal, to ±1-degree, whilst for hous-
ings without the back seal, up to ±5-degrees
can be accommodated Mounting instructions
By contrast, dynamic misalignment: the
operational misalignment of the shaft
(between bearings on the same shaft), must
be limited to no more than a few minutes of
arc
