The AirTAC Airtac SC40 Standard Cylinder SC40X90TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 90mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X90TC is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a 90 mm stroke. It generates a push force of 628 N at 0.5 MPa and 1130 N at the maximum operating pressure of 0.9 MPa, driven by a 16 mm diameter piston rod.
This model includes the TC centre trunnion mounting, supplied together with the TCM1 bracket (accessory code F-SC40TC), allowing the cylinder to pivot during operation. The body length A is 142 mm, and the total extended length is approximately 232 mm. Standard PT1/4 ports and TPU seals suit filtered air at -20 to +70 °C.

The trunnion mount lets the cylinder swing as it actuates a diverter flap on a packaging line, handling the 628 N push force to redirect products reliably.
Ideal for pivoting clamp arms on welding or assembly jigs, where the 90 mm stroke provides a compact clamping motion and the trunnion absorbs the arc movement.
Operates a pivoting gate on a seed or grain hopper. The double-acting air control opens and closes the chute positively, with the cushion softening end-of-stroke impact.
Choose the SC40X90TC when your application requires a pivoting mount and around 628 N of force at standard plant pressure. If you need more force, stepping up to the 50 mm bore delivers 982 N push at the same 0.5 MPa. For a fixed, non-pivoting installation, the basic SC40X90 or a foot-mounted LB variant may be a simpler choice. To ensure a correct replacement, match five points: 40 mm bore, 90 mm stroke, PT1/4 port thread, TC centre trunnion mounting, and the absence of a magnet.
Quick checklist
At 0.5 MPa air pressure, 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. The theoretical maximum force at 1.0 MPa is 128 kgf.
Yes, provided the original is a tie-rod cylinder with a 40 mm bore, 90 mm stroke, PT1/4 ports, and a centre trunnion mount. The SC series is shorter than ISO 15552 cylinders, so always check the body length (142 mm) and pivot point dimensions against your machine before ordering.
