Parker’s CR4000 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. Parker Daedal crossed roller slides are rated for over 100 million inches of travel at specified load.

The 4000 Series Crossed Roller Linear Slides are the ideal mechanisms for providing precise, low friction, linear motion. Two linear rows of bearings (one located on each side of the base), support the carriage and provide smooth, accurate, linear translation.
