The AirTAC Airtac SC40 Standard Cylinder SC40X101 is a genuine double-acting standard air cylinder with a Ø40mm bore and 101mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X101 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a 101 mm stroke. At a standard 0.5 MPa supply, it generates 628 N of push force and 528 N on the pull stroke, making it a capable mid-range actuator for general industrial tasks.
This model uses a 16 mm diameter piston rod with an M12x1.25 rod thread and PT1/4 ports. The body length A is 142 mm, giving a total extended length of approximately 243 mm. Its 21 mm adjustable air cushion at each end decelerates the piston smoothly, reducing end-of-stroke impact noise and vibration without locking the position.

The 101 mm stroke and 628 N push force effectively actuates gates or diverters on compact conveyor lines, sorting lightweight packages or components with reliable, repeatable motion.
Ideal for pneumatic clamping in assembly jigs, delivering a controlled 628 N force to hold parts during drilling, welding, or bonding operations without excessive tooling weight.
Provides a short, firm pressing stroke for sealing cartons or applying labels in semi-automatic packaging stations, where the adjustable cushion ensures a clean, low-impact stop.
Select the SC40X101 when your application needs a compact force around 628 N at 0.5 MPa. If you require more force, stepping up to the 50 mm bore SC50 series provides 982 N push at the same pressure. For lighter, faster cycles, the 32 mm bore SC32 series offers 402 N push.
For a direct replacement, match five key points: 40 mm bore, 101 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and no magnet. This cylinder is not dimensionally interchangeable with ISO 15552 profiles; it is a shorter tie-rod design. If your stroke exceeds 300 mm, evaluate side-load forces on the 16 mm rod and consider an external guide rail.
Quick checklist
At 0.7 MPa operating pressure, the SC40X101 delivers 879 N of push force and 739 N of pull force. The maximum theoretical push force at 1.0 MPa is 128 kgf (approx. 1255 N).
This specific SC40X101 model does not include the -S magnet option, so standard CMSG or DMSG sensors cannot be directly mounted on the barrel. To use sensors, order the SC40X101-S variant which has a built-in magnetic piston ring.
