The AirTAC Airtac SC40 Standard Cylinder SC40X80 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 SC40X80 is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (up to 1130 N at 0.9 MPa). Its 80 mm stroke suits short-transfer and clamping operations where a compact tie-rod design is preferred.
This model features a 16 mm diameter piston rod, PT1/4 ports, and a 21 mm adjustable air cushion at each end. The body length A is 142 mm, keeping the overall extended length to 222 mm. Standard TPU seals provide reliable service from -20 to +70 °C.

The 628 N push force at 0.5 MPa is ideal for stopping or diverting small to medium packages on a conveyor line with an 80 mm stroke.
Use the SC40X80 for pneumatic clamping in machining or welding jigs where the 16 mm rod provides adequate rigidity for the short stroke.
The compact 222 mm extended length fits narrow pusher stations, reliably diverting cartons off a main line with adjustable cushioning to reduce impact.
For applications needing more force, step up to the 50 mm bore SC50 series, which provides 982 N at 0.5 MPa. If a shorter overall length is critical, the 32 mm bore SC32 offers 402 N at the same pressure. The 80 mm stroke is a standard option within the 1200 mm maximum for this bore.
When replacing an existing cylinder, match five points: 40 mm bore, 80 mm stroke, PT1/4 port thread, basic mounting (no accessory brackets), and confirm the magnet requirement (this model has no built-in magnet).
Quick checklist
At 0.7 MPa operating pressure, the SC40X80 produces 879 N of pushing force and 528 N of pulling force. The maximum theoretical force at 1.0 MPa is 128 kgf. Always size the cylinder using the force at your actual working pressure.
This specific SC40X80 model does not include a built-in magnet. To use CMSG or DMSG sensors, order the SC40X80-S variant, which has a magnetized piston. Standard tie-rod cylinders require the -S suffix for sensor compatibility.
