The AirTAC Airtac SC40 Standard Cylinder SC40X120TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 120mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X120TC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). With a 40 mm bore and 120 mm stroke, it features a 16 mm diameter piston rod and an adjustable air cushion of 21 mm to decelerate the load smoothly at end of travel.
This model is configured with a centre trunnion (TC) mount, supplied with the TCM1 bracket (part code F-SC40TC), allowing the cylinder to pivot during operation. The body length A is 142 mm, giving a total extended length of approximately 262 mm. It uses PT ports and standard TPU seals for a working range of -20 to +70 °C.

The 120 mm stroke and pivoting TC mount make this cylinder a reliable actuator for diverting small packages or components on conveyor lines, handling 628 N of push force at standard pressure.
Ideal for pneumatic clamping systems in machining or assembly, where the 40 mm bore provides a secure 1130 N clamping force at 0.9 MPa and the trunnion mount allows the cylinder to self-align.
Operates discharge gates or diverter chutes on agricultural processing equipment. The TPU seals and PT ports handle filtered compressed air reliably in dusty environments within -20 to +70 °C.
Choose the SC40 when your application needs up to 628 N at standard line pressure. If you require more force, step up to the SC50 bore which provides 982 N at 0.5 MPa; for a lighter, more compact solution, the SC32 delivers 402 N. The TC centre trunnion mount is ideal for swinging or pivoting loads, allowing the cylinder body to rotate around the trunnion axis.
For a direct replacement, match five key points: bore (40 mm), stroke (120 mm), PT port thread, centre trunnion (TC) mounting accessory, and the absence of a built-in magnet. This SC cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 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 reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length (A=142 mm) than an equivalent ISO 15552 cylinder. It is not dimensionally interchangeable. Replace only with another AirTAC SC tie-rod cylinder matching bore, stroke, PT ports, and TC mount.
