The AirTAC Airtac SC40 Standard Cylinder SC40X80CA 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 SC40X80CA is a 40 mm bore, 80 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod family. It delivers 628 N of push force at 0.5 MPa (879 N at 0.7 MPa), driven by a 16 mm diameter piston rod with M12x1.25 male threads.
This model is configured with a rear single clevis mount (CA) for applications where the cylinder body must pivot. The adjustable air cushion at each end is 21 mm long, and the total body length A is 142 mm. Operating pressure spans 0.15–1.0 MPa with filtered air, and the standard TPU seals suit a temperature range of -20 to +70 °C.

The 628 N output at 0.5 MPa and compact 80 mm stroke suit pneumatic clamping fixtures on CNC mills or welding jigs, where the rear clevis lets the cylinder self-align.
Mount this cylinder on a pivoting CA bracket to actuate a diverter gate on a conveyor line. The 16 mm rod and 21 mm cushion handle the repetitive end-of-stroke impacts reliably.
Ideal for push-pull linkages on agricultural sorting equipment. The rear single clevis simplifies installation into existing pinned joints, and the tie-rod design allows field maintenance.
Choose the SC40X80CA when your load requires up to about 628 N of push force at standard plant pressure. If you need more force, step up to the 50 mm bore SC50 series, which provides 982 N at the same 0.5 MPa. For lighter, faster-moving loads, the 32 mm bore SC32 series offers 402 N.
To replace an existing cylinder, match five points: 40 mm bore, 80 mm stroke, PT1/4 port thread, the CA rear clevis mounting, and confirm the magnet option (this unit has no built-in magnet). The CA clevis, ordered as accessory F-SC40CA, allows the cylinder to swing during actuation—ensure the pivot pin is sized for the reaction forces.
Quick checklist
At 0.5 MPa the theoretical push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so mounting dimensions and body length are not interchangeable. It is a direct replacement only for another AirTAC SC tie-rod cylinder matching the 40 mm bore, 80 mm stroke, PT1/4 ports, and CA rear clevis mount.
