Huco’s DA pneumatic cross roller slides combine an ultra low friction pneumatic actuator and precision roller slide in what it describes as a beautifully simple design.
The actuator comprises a pair of miniature, pneumatic rams with graphitised-carbon pistons running in Pyrex cylinders. Neither seals nor lubrication are used. Both dynamic and static friction are very low and almost equal, making the actuators ideal for low to moderate force applications where conventional designs often suffer from stiction.The pistons are self aligning, operated vacuum or air pressure, and act through connection rods. The low coefficient of expansion and excellent stability of the system ensure highly accurate repeatability of positioning.
