The AirTAC Airtac SC40 Standard Cylinder SC40X65N is a genuine double-acting standard air cylinder with a Ø40mm bore and 65mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X65N is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, featuring a 40 mm bore and a 65 mm standard stroke. It delivers a push force of 628 N at 0.5 MPa and 1130 N at 0.9 MPa, driven by a 16 mm diameter piston rod with M12x1.25 threads.
This model is configured with NBR (nitrile) seals for general-purpose use within the standard -20 to +70 °C temperature range. The compact tie-rod body has a length of 142 mm, resulting in a total extended length of approximately 207 mm, making it a space-efficient choice for linear automation tasks.

The 65 mm stroke and 628 N push force at 0.5 MPa are ideal for actuating compact diverter gates or part stops on light-duty conveyor lines.
Provides consistent clamping force for woodworking or light metal fabrication jigs, where the NBR seals offer reliable performance in standard shop air environments.
Delivers a quick, repeatable 65 mm linear push to eject small packaged goods from a filling or labeling station into a bin or onto a chute.
Choose the SC40X65N for applications needing around 628 N of force at standard plant pressure. If your load requires more thrust, stepping up to the 50 mm bore SC50 series provides 982 N at the same 0.5 MPa pressure. For lighter, high-speed tasks, the 32 mm bore SC32 series offers 402 N.
When replacing an existing cylinder, match five key points: 40 mm bore, 65 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and no magnet. The SC is a tie-rod cylinder 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 increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than a comparable ISO 15552 cylinder. For a direct replacement, match the SC40 bore, 65 mm stroke, PT port thread, and basic mounting configuration.
