The AirTAC Airtac SC40 Standard Cylinder SC40X160H is a genuine double-acting standard air cylinder with a Ø40mm bore and 160mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X160H is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, factory-equipped with Viton (FKM) seals for reliable operation in high-temperature environments up to 150°C. With a 40 mm bore and 160 mm stroke, it generates 628 N of push force at 0.5 MPa and 1130 N at the maximum operating pressure of 0.9 MPa, making it a capable mid-range actuator.
This model features a 16 mm diameter piston rod with M12x1.25 threads and PT1/4 ports. The adjustable air cushion at each end is 21 mm long, providing smooth deceleration. The body length A is 142 mm, giving a total extended length of approximately 302 mm. This genuine AirTAC cylinder is built for demanding thermal applications where standard seals would degrade.

Viton seals allow this cylinder to operate continuously in ambient temperatures up to 150°C, making it suitable for actuators near ovens, autoclaves, or foundry equipment where standard seals would fail.
The 628 N push force at 0.5 MPa is ideal for clamping and ejecting parts in heated platen presses, thermoforming tools, and rubber molding machines, where both force and thermal resilience are required.
Used in environmental test chambers and sterilization equipment, the SC40X160H provides consistent 160 mm linear actuation under sustained heat, with PT1/4 ports for easy integration with standard pneumatic circuits.
Choose the SC40X160H when your application requires a 40 mm bore cylinder that can withstand ambient or media temperatures from 0 to 150°C. If you need more force, the SC50 series provides 982 N of push at 0.5 MPa; for a lighter, more compact solution, the SC32 delivers 402 N. The 160 mm stroke is a standard length within the 40 mm bore's maximum of 1200 mm.
For replacement, match these five points exactly: 40 mm bore, 160 mm stroke, PT1/4 port thread, basic (no mounting accessory), and no magnet. The Viton seal variant is critical for high-temperature compatibility and cannot be substituted with a standard TPU seal model.
Quick checklist
At 0.7 MPa operating pressure, the SC40X160H delivers 879 N of push force and 528 N of pull force. The theoretical maximum push force at 1.0 MPa is 128 kgf. Always design your application using the pull force value if the rod is in tension.
Yes, the SC40X160H is a direct dimensional replacement for the standard SC40X160. The only difference is the Viton (FKM) seal material, which upgrades the temperature rating from -20 to +70°C to 0 to +150°C. All mounting interfaces, port sizes, and stroke dimensions remain identical.
