California Residents: Prop-65 Warning
Parker’s SK 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 Daedal crossed roller stages are rated for over 100 million inches of travel at specified load.
The SK Series features end plates for positioning, making them ideal for factory automation applications. The SK is knob driven with excellent precision, smooth motion, and a long life in a compact footprint.
