The AirTAC Airtac SC40 Standard Cylinder SC40X70FA is a genuine double-acting standard air cylinder with a Ø40mm bore and 70mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X70FA is a 40 mm bore, 70 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It generates a push force of 628 N at 0.5 MPa and 1130 N at the maximum operating pressure of 0.9 MPa, making it a capable actuator for medium-duty linear tasks.
This model is factory-assembled with an FA front rectangular flange (part F-SC40FA) for secure panel or bulkhead mounting on the rod side. The 16 mm diameter chrome-plated rod and PT1/4 port ensure reliable fluid connection, while the adjustable air cushion decelerates the piston smoothly over the final 21 mm of travel.

The front flange mount and 628 N force at 0.5 MPa make this cylinder ideal for rigidly mounted work-holding clamps on assembly jigs.
Reliable actuation for stopping or diverting lightweight packages on conveyor lines, where the FA flange bolts directly to the frame.
Provides consistent linear thrust for small pneumatic presses, riveting stations, or light forming tools requiring a fixed front mounting point.
For higher force requirements, stepping up to the 50 mm bore SC50 series provides 982 N at the same 0.5 MPa pressure. If space is a constraint, the 32 mm bore offers 402 N. The 70 mm stroke is well within the 1200 mm maximum standard stroke for this bore. When replacing an existing cylinder, match five points exactly: bore, stroke, PT port thread, FA front flange mounting, and the absence of a magnet sensor option.
Quick checklist
At the standard operating pressure of 0.5 MPa, the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
Yes. The FA suffix designates a front rectangular flange (accessory F-SC40FA) bolted to the rod-end head, designed for rigid face-mounting onto a machine panel or bulkhead.
