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.

Ball Slides
Ball slides are simple linear motion devices that provide smooth linear motion, accurately controlled by the rotation of the drive mechanism. 
Crossed Roller Slides
Crossed roller slides are simple linear motion devices that consist of a stationary base and a moving carriage. The rollers are crossed at a 90° angle in an alternating fashion and are enclosed in the rails, which have a machined V-shaped groove to support the rollers.
Linear Slides and Linear Stages
Linear slides are simple linear motion devices composed of a stationary base and a moving carriage. Linear stages are slides with a drive mechanism that provide controlled, precise positioning along a linear axis.
Ball Splines
Ball splines provide nearly friction-free linear motion while simultaneously transmitting torsional loads. The path of the bearing balls is straight, not helical, which allows for a very efficient coupling device suitable for a variety of applications.
