The AirTAC Airtac SC40 Standard Cylinder SC40X380TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 380mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X380TC 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 380 mm stroke, it features a 16 mm diameter piston rod and PT1/4 ports, making it a capable mid-range actuator for industrial automation tasks.
This model is equipped with a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC40TC), allowing the cylinder to pivot during operation—ideal for swinging or articulating loads. The adjustable air cushion at each end decelerates the piston smoothly, reducing end-of-stroke impact and extending service life.

The 380 mm stroke and pivoting trunnion mount suit conveyor diverter gates, where the cylinder body swings to redirect packages or materials between lanes.
Delivers 628 N of clamping force at standard line pressure, ideal for holding workpieces in CNC fixtures or welding jigs where a compact tie-rod cylinder is preferred.
Used on hopper doors or chute controls on farm equipment, the trunnion mount absorbs misalignment while the TPU seals handle dusty, ambient-temperature environments.
For applications needing more force, stepping up to a 50 mm bore SC50 series provides 982 N at 0.5 MPa. If space is a constraint, the 32 mm bore SC32 series offers 402 N. The 380 mm stroke is within the 1200 mm maximum standard stroke for this bore. When using strokes over 300 mm, be mindful of side loads; the 16 mm rod may require an external guide or guided cylinder to prevent rod bending and bearing wear.
To ensure a correct replacement, match five key points: bore (40 mm), stroke (380 mm), port thread (PT1/4), mounting accessory (centre trunnion TC with TCM1 bracket), and magnet option (none). This cylinder is not an ISO 15552 profile; it is a tie-rod design and is dimensionally interchangeable only with another AirTAC SC40 cylinder of the same configuration.
Quick checklist
At 0.5 MPa, the cylinder provides 628 N of push force and 528 N of pull force. 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 SC40X380TC is a double-acting cylinder and does not lock or hold position when air pressure is removed or the valve is centered. The piston will drift. For load-holding, you must add an external rod brake, a pilot-operated check valve, or a mechanical lock.
