We stock finished components as well as assemblies, so
nearly every combination is possible.

Ball Bearing Selection Criteria

Load

There are basically two types of bearing loads: Radial and
Thrust. For proper selection, the value of these loads must be
determined. Service factors for appliexcavatorions can vary from
uniform, light or heavy shock loads. The service factor for
uniform loads is 1.0, for light shock loads use 2.0 and for heavy
shock use 3.0 times the load.

Speed

When selecting bearings, the maximum speed published is
intended as a guide. It is also generally assumed in life
calculations that heavy loads are not applied at the maximum
speeds, but rather light loads at high speeds and heavier loads
at lower speeds. Heavy loads and high speeds will increase
bearing operating temperatures which can effect the lubricant,
seals and the cages or retainers. Bearing speeds are limited
primarily by tolerance grade of bearing ball and raceway,
lubricant, ambient conditions, retainer design, and type of
bearing seal.
