The hard anodized body, with a thicker film than competitors, offers superior resistance to corrosion and scratches, while internal roughness is minimized using diamond tools to reduce sealing friction; Teflon-coated metal bushings at the top and bottom provide excellent wear resistance and stability across temperature changes, unlike some competitors who use plastic bushings; the special grease for pneumatic actuators has high extreme pressure properties and does not scatter or volatilize, and various coating options include epoxy (powder/liquid), polyester, urethane, Teflon, and electroless nickel.

The cast piston minimizes metal-to-metal contact with a guide ring and pad, and tightly controls tolerances to prevent leaks caused by O-ring wear. 

The snap rings on both sides of the piston pin prevent the pin from coming out.

Due to the polished friction surface of the shaft, the grinding stem experiences extremely low wear, resulting in a long lifespan, while machining surface tolerances are managed with a dedicated jig.

The cast aluminum end cap undergoes a powder coating surface treatment, providing long-lasting color, resistance to discoloration, and consistent thickness. Additionally, the 4-axis screw is stabilized corrosion resistance. Additionally, the 4-axis screw is stabilized by simultaneously tightening four bolts using an electric driver and servo motor, ensuring no distortion of the sealing.

The powder-coated spring is resistant to corrosion and has a long service life. (Powder coating is limited to SCOTCK YOKE only.) For AS50-AS100, three types of springs (W, M, S) are available, while for AS125-AS300, six types (W, WM, WS, M, MS, S) are available, allowing for selection based on the site’s pressure, ensuring competitive pricing.

The stopper bolt, located on the opposite side of the air port, avoids interference from solenoid valves, regulators, etc., making it convenient to use. The angle adjustment range is as follows: STD 90˚-5˚+10˚ (both open and close), Center stopper 90˚-5˚+45˚ (both open and close), and End cap stopper 90˚-5˚+90˚.
