Manual Driven, Cross Roller Bearing Guided, Large Frame Linear Positioning Stages - CR4900 Series

Parker’s CR4900 Series precision crossed roller stages provide controlled, precise point-to-point positioning along a linear axis. Stages are comprised of two basic components: a precision linear crossed roller slide which serves as a linear bearing and guide, and a drive mechanism which accurately moves and positions the slide top along the linear axis. Crossed roller positioning stages offer exceptional load carrying capability, approximately 2 to 2-1/2 times that of comparably sized ball bearing stages. Additionally, crossed roller stages provide up to five times the life expectancy of the ball bearing stages without degradation of performance. Parker’s crossed roller stages are rated for over 100 million inches of travel at specified load.

The 4900 Series is our largest crossed roller manual positioner. The 4900 Series offers high payload capacity, a variety of drive mechanisms, and excellent precision.
