Crossed roller slides offer exceptional load carrying capability, approximately twice that of comparably sized ball slides. Additionally, crossed roller slides provide up to five times the life expectancy of ball slides without degradation to performance. A leading manfacturer advertises that crossed roller slides are rated for over 100 million inches of travel at specified load.
Crossed Roller Slide facts
A crossed roller slide bearing system is composed of two rows of rollers. Each roller is alternately crossed at 90° with the next and captured in “V” grooves, located on the base and top. Rollers provide a larger (line) contact surface than ball bearings, a crossed roller slide has higher load carrying capability than a ball slide of comparable size.
Crossed roller slides are preloaded during the manufacturing process to eliminate any side play and to provide a uniform coefficient of friction. Like the ball slide, the crossed roller slide is not made for use in shock load applications.
