Extruded aluminum (acc. to ASTM 6005) cylinder body, fine grinded and finished cylinder wall, and the advanced corrosion-resistant construction, result in low friction, long service life and strong corrosion resistance.

Double piston rack and pinion design, with compact structure and symmetric mounting position, benefits changing the direction of output shaft rotation and achieves long service life and high response.

Composite bearings and guide rings installed in the back of piston rack for accurate response

The preload and coated spring for long service life

Precision manufacturing of rack and pinion ensures efficient tooth engagement and provides positive piston thrust

Stainless steel fasteners enhance the corrosion resistance

Output shaft, screw and top mounting size conform to NAMUR standards. Air interface conforms to NAMUR standards. Bottom mounting size accords to ISO 5211, DIN 3337

Double acting and single acting (spring return) models are of the same shape and dimension for good interchangeability.
