Features
Ductile iron housing, piston and end caps provide long life and durable, cost-effective operation.
High strength alloy steel or 17-4PH stainless output shaft transmits torque without fatigue.
Sintered bronze or PTFE polytetrafluoroethylene) composite output shaft bushings eliminate side loading of valve stem to maximize stem packing performance.
Strong, corrosion-resistant chrome-plated steel piston rod for enduring high cycle applications.
Sintered bronze piston rod bushings provide low-friction support and precise alignment to increase efficiency, reduce maintenance and extend actuator life.
Heat-treated stainless steel thrust pin and rollers transfer piston force to yoke to reduce friction for longer life and more efficient torque transmission.
PTFE guide bands ensure low-friction piston guidance, protecting cylinder walls from scoring and extending seal performance with a continuous cylinder wiping action.
