|Bearings can be preloaded by
the locating method or by the spring method. Typical preloading methods
are given in the table.
||When the size of the preload
is the same, the locating method produces a smaller deflection in bearings
than the spring method if the bearing is exposed to an axial load. This
results in a high rigidity.
||When the spring method is used,
the spring absorbs load variation or shaft elongation and contraction, making
it possible to apply the preload stably with minimum variation.
||A greater preload is achievable
when the locating method is used.
