To get the longest working life out of a linear bearing, keep it
clean and well lubricated. This common-sense advice may
sound easy enough to follow. Yet in the real world of roundthe-
clock, high-cycle manufacturing operations, bearings
do get dirty and dry.
And when either of these conditions happens, linear
bearings will wear prematurely. In the worst-case scenarios,
contamination and inadequate lubrication can create
metal-on-metal contact between the bearing's rolling
elements and raceway. This can cause excessive wear in
the form of denting, pitting or galling results.
