Airpot Corp. has announced a long length (up to 1 m) Airpel Anti-Stiction actuator. The actuator is said to meet the needs of coordinate measuring machine and other metrology device manufacturers for a low friction counterbalance device to allow smooth movement and precise positioning of the z-axis measuring arm while manipulating the device through its measurement range. Airpel Anti-Stiction cylinders use a simple pneumatic cylinder with an internal design that is said to allow for virtually zero friction, while precisely controlling the amount of counter force needed to eliminate the effect of driver and probe arm mass.

The Airpel unit provides increased safety since it can prevent a crash in a power off situation. Units respond to forces as low as a few grams and pressures less than 0.2 psi.
