AT-DA190 Rotary Double Acting Rack and Pinion Pneumatic Actuator Manufacturer

⇒ Design & Construction of Pneumatic Actuator

• Extruded aluminum ASTM6005 body with both internal and external corrosion protection having honed cylinder surface for longer life and low coefficient of friction.

• Dual piston rack and pinion design for compact construction, symmetric mounting position, high-cycle life and fast operation, reverse rotation can be accomplished in the field by simply inverting the pistons.

• Multiple bearings and guides on racks and pistons, low friction, high cycle life and prevent shaft blowout.

• ​​Modular pre-loaded spring cartridge design, with coated spring for simple versatile range, greater safely and corrosion resistance, longer cycle life.​

• Fully machined teeth on piston and pinion for accurate low backlash rack and pinion engagement, maximum efficiency, stainless steel fasteners for long term corrosion resistance.

• Full conformance to the latest specifications: ISO5211, DIN3337 and NAUMR or product interchange ability and easy mounting of solenoids, limit switches and other accessories.
