Pneumatic Actuator AT Series (Double-Acting & Single-Acting)

I. Actuator Body

Boy material is aluminium alloy. Internal and external surface are treated with anodic oxidation and polishing. Outer surface is nickle plated so that the anti-corrosion fuction of actuator and minimum friction against pistons can be guaranteed.

II. End Cover

End cover material is die-casting aluminium. End cover is treated with epoxy polyester so as to best guarantee the anti-corrosion performance. 

III. Drive Shaft

The drive shaft material is medium carbon steel with fine processing and nickle plating so that the pistons have better quality in anti-corrosion, anti-friction, etc.

IV. Piston

Piston material is die-casting aluminium alloy. Maxmium torque can be output when the actuator is actuated with certain pressure. 

V. Piston Seal

NBR-70 rubber sealing is applied to ensure the normal and reliable performance of actuator under normal temperature. FPM can be also applied according to clients' requirements. 

VI. Travel Adjustment

Plus/Mimus 5 degree travel can be adjusted through the two bolts.
