The AirTAC Airtac SC40 Standard Cylinder SC40X80N is a genuine double-acting standard air cylinder with a Ø40mm bore and 80mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X80N is a double-acting tie-rod cylinder with an 80 mm stroke and 40 mm bore, equipped with NBR (nitrile) seals for general-purpose pneumatic applications. It produces 628 N of push force and 528 N of pull force when operated at 0.5 MPa, making it a capable mid-range actuator for clamping, pressing, and transfer tasks.
This model features a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 ports. The adjustable air cushion at each end provides a 21 mm deceleration zone to reduce end-of-stroke impact. The body length A is 142 mm, giving a total extended length of approximately 222 mm for this standard-stroke configuration.

The 80 mm stroke and 628 N push force efficiently shift small components between conveyor lanes or into inspection nests on automated packaging lines.
Ideal for pressing bushings, pins, or connectors into housings where a controlled 528 N pull force is also needed for retraction of tooling.
Provides consistent clamping force for woodworking or light metal fabrication jigs. The NBR seals offer reliable performance with standard compressed air systems.
For applications requiring more force, consider stepping up to the 50 mm bore SC50 series, which provides 982 N of push force at 0.5 MPa. If space is constrained and lower force is acceptable, the 32 mm bore SC32 series delivers 402 N at the same pressure. Always match the port thread (PT1/4), mounting accessories, and seal material when replacing an existing cylinder.
For this 80 mm stroke, side loading is typically minimal, but ensure the load is guided and aligned with the rod axis to prevent premature rod bearing and seal wear. If the application involves any lateral force, an external guide rail or a guided cylinder should be used to protect the rod and bearing.
Quick checklist
At the standard operating pressure of 0.5 MPa, the cylinder delivers 628 N of push force on extension and 528 N of pull force on retraction. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
It is a direct dimensional replacement for any AirTAC SC series 40 mm bore cylinder with the same stroke, PT port thread, and basic mounting configuration. Because the SC is a tie-rod design, it is shorter than an ISO 15552 cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders. Always verify the body length (142 mm) and port size before substituting.
