The AirTAC Airtac SC40 Standard Cylinder SC40X160N is a genuine double-acting standard air cylinder with a Ø40mm bore and 160mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X160N is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 628 N at 0.5 MPa and up to 1130 N at the maximum operating pressure of 0.9 MPa. With a 40 mm bore and a 160 mm stroke, this model features a 16 mm diameter piston rod and an M12x1.25 rod thread, making it a robust choice for medium-duty linear applications.
This specific configuration uses NBR (nitrile) seals, which provide reliable performance within the standard temperature range of -20 to +70 °C. The cylinder body has a length of 142 mm, resulting in a total extended length of approximately 302 mm. It includes an adjustable pneumatic cushion to decelerate the piston smoothly at the end of its stroke.

Operates gates and diverters on light-duty conveyor systems, where the 160 mm stroke provides sufficient travel for sorting small packages or components.
Provides consistent clamping force for woodworking or light metal fabrication jigs, with the NBR seals offering good resistance to oils in a workshop environment.
Actuates levers and linkages on planting or harvesting equipment, where the 628 N push force is adequate for adjusting chutes and metering mechanisms.
Select the SC40X160N for applications needing around 628 N of force at standard plant pressure. If your load requires more thrust, consider stepping up to the SC50 series, which provides 982 N of push force at the same 0.5 MPa. For lighter, more precise tasks, the SC32 series offers 402 N.
When replacing an existing cylinder, ensure a match on all five critical points: 40 mm bore, 160 mm stroke, PT port thread, basic (no) mounting, and the absence of a magnet. This tie-rod cylinder is shorter than an ISO 15552 profile cylinder and is not dimensionally interchangeable with them.
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. The force increases linearly with pressure, reaching a maximum push force of 1130 N at the 0.9 MPa operating limit.
No. The SC40X160N is a double-acting cylinder and will not hold its position if air pressure is lost or the valve is centered. The piston will drift or drop under load. To hold a position safely, you must add an external rod brake or a pilot-operated check valve.
