High load carrying capacity
High stiffness for rigid bearing application
Low friction
Long service life
Surface protection and corrosion resistance,crossed roller slides (also referred to as crossed roller bearings) are linear bearings that use cylindrical rollers—as opposed to balls—to carry a load. The rollers ride between parallel guides in which v-shaped grooves have been ground

In contrast, crossed-roller bearings that use cylinder-shaped rollers are more accurate and rigid mechanical linear components.
