CS Series
Overview
Rollerdrive RA Series

The CS Series is a backlash free servo driven linear actuator designed for moving heavy loads at high speeds with accurate positioning. Stroke length is fully programmable and unlimited in either direction with additional rail sections. This versatile system mounts in any position. The cam follower rail can be mount fixed with the block traversing or the block can mount fixed. Multiple actuators can serve as a pick & place handler or X-Y table. With the internal cam ratio and optional inline servo reducer, many load and speed requirements are achievable.

RollerDrive CNC Technology

Features

Long Stroke Length
Unlimited stroke length and fully programmable with the servo drive motor.
Heavy Load & High Speed
Heavy loads move accurately with combined internal cam ratio and multiple inline reducer ratios.
• CS30 can move 300kg a distance of 1 meter in 1.5 second
Accuracy
• Positioning: 0.03mm / 300mm
• Repetitive: ± 0.02mm (± 0.01mm without optional inline reducer)
No Backlash, Rolling Contact
Cam follower rails are preloaded into the internal cam for backlash free motion.
