Pneumatically actuated crossed roller slide assemblies controlled by a pair of Airpot actuators, provide extremely low friction and stiction characteristics. A light touch or physical obstruction will stop the unit's movement to prevent damage to delicate and expensive equipment and parts. Low pressure operation is possible. The PNRE series requires less than 10 psi to operate.

Each slide is comprised of an aluminum carriage straddling an aluminum base. Using a bearing system containing cylindrical steel rollers, the carriage glides, almost friction-free, over the base. The rollers, alternately crisscrossed with each other, move between a set of four partially flat, parallel, smooth rods on each side of the base. The Isotech Straight Line Design makes possible low stiction and friction characteristics, unlike recirculating designs in which the rolling elements must turn corners and often slide against each other as they travel.

Airpot Pneumatic Actuators are ultra low friction devices designed to provide precise, repeatable motion at very high or low speeds without seals or lubrication. They run clean and operate over a wide temperature range with no change in performance. The basic construction consists of a graphitized carbon piston, precision ground to millionths of an inch TIR, inside an annealed, borosilicate glass cylinder with a precision fire polished bore.

• Low Pressure Operation: <10 PSI.
• Low Friction: <1gm.
• Wide range variable speed: smooth, slow and high speed capabilities.
• Precise, gentle handling of wafers, chips and surface mount devices.
• Ideal for fluid sample handling and adhesive deposition.
• Isotech crossed roller slide, driven by two (2) air actuated dashpots, provides a frictionless interface for up to 2" travel n a compact package.
