rotaryrack-and-piniondouble-acting

Indicator A position indicator with Namur mounting is standard on all NUTORK pneumatic actuators for mounting accessories. Pinion The hardened alloy steel pinion is precision ground and Nickel plated (over 15um) in order to reduce friction, provide maximum wear resistance. Full conformance with the newest standards of ISO5211 & DIN3337. The dimensions can be customized and as options, stainless steel and aluminium alloy are also available. Actuator Body The aluminum extrusion is hard anodized(over 30um) to protect against wear and corrosion while reducing piston friction to the absolute minimum. Other options such as Nickel, Ceramic, PTFE, Polyester coated are available. End Caps Epoxy coated(over 80um) die cast aluminum end caps provide maximum resistance against potentially corrosive elements. Other treatments such as Nickel, Ceramic, PTFE,Polyester coated are available. Pistons The precisely-balanced and hard anodized treatment (over 30um)die cast aluminum pistons are fitted with high quality rings and guides. The twin rack and piston design creates a constant torque output on all actuators. Travel Adjustment The standard adjustment is ± 5°in both the open and closed positions through easily accessible external adjustment bolts.
