The AirTAC Airtac SC40 Standard Cylinder SC40X350 is a genuine double-acting standard air cylinder with a Ø40mm bore and 350mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X350 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa. With a 40 mm bore and a 350 mm stroke, its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range linear tasks.
This model uses a PT1/4 port and M12x1.25 rod thread. The body length A is 142 mm, giving an extended length of approximately 492 mm. As a genuine AirTAC component, it is built with a TPU seal for standard temperature operation from -20 to +70 °C.

Directs cartons on a conveyor line, using the 350 mm stroke to push items onto a branching lane with consistent force at standard plant air pressure.
Applies 628 N of holding force to secure medium-sized workpieces during drilling or welding, with the adjustable cushion reducing impact at clamp closure.
Operates a vertical lift gate on a material handling cart, using the double-acting function to both raise and lower the barrier smoothly.
Choose the SC40X350 when your application needs around 628 N of force. If you require significantly more thrust, consider stepping up to the SC50 bore, which provides 982 N at the same 0.5 MPa pressure. For lighter, more compact tasks, the SC32 bore offers 402 N.
For a 350 mm stroke, ensure the load is guided and side forces are minimal. Long, unsupported strokes on a 16 mm rod can experience bending under lateral loads. To match this cylinder for replacement, verify five points: 40 mm bore, 350 mm stroke, PT1/4 port thread, basic (no) mounting, and no magnet.
Quick checklist
At the standard operating pressure of 0.5 MPa, the push force is 628 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 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 than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. It directly replaces another AirTAC SC40 cylinder with the same stroke, port, and mounting configuration.
