The AirTAC Airtac SC40 Standard Cylinder SC40X80SFA 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 SC40X80SFA is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at the maximum operating pressure of 0.9 MPa. With an 80 mm stroke and a 16 mm diameter piston rod, this model is well-suited for short-to-medium linear movements in clamping, pressing, and ejecting tasks.
This configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG, DMSG, or EMSG sensors, enabling precise end-of-stroke detection. The FA front rectangular flange (F-SC40FA) allows for rigid mounting on the rod-end cap, ensuring stable alignment in panel-mounted applications.

The 628 N force at 0.5 MPa and 80 mm stroke are ideal for fixturing and part-clamping operations on CNC machines or assembly jigs, with magnetic sensors confirming clamp engagement.
Provides a robust 80 mm linear push to divert or stop items on a conveyor line. The front flange mount ensures a rigid, space-efficient installation perpendicular to the conveyor frame.
The FA front flange allows the cylinder body to be bolted directly through a machine panel. Delivers up to 1130 N of pressing force at 0.9 MPa for light assembly or forming tasks.
For applications requiring more force, consider stepping up to the 50 mm bore SC50 series, which provides 982 N at 0.5 MPa. If space is a constraint, the 32 mm bore offers 402 N. When replacing this cylinder, ensure the new unit matches the 40 mm bore, 80 mm stroke, PT1/4 port thread, front flange FA mounting, and built-in magnet for sensor compatibility.
Quick checklist
At the standard operating pressure of 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows you to mount AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the cylinder barrel's tie-rod slots to detect piston position.
