The AirTAC Airtac SC40 Standard Cylinder SC40X180STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 180mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X180STC is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa), making it a capable mid-range actuator for moderate loads. With a 180 mm stroke and a 16 mm diameter piston rod, it suits compact linear movements where the centre trunnion mount allows the cylinder body to pivot as the load travels through an arc.
This model includes a built-in magnet, so CMSG, DMSG, or EMSG reed and solid-state sensors can be clamped directly onto the tie-rod barrel for non-contact position sensing. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact. The body length A is 142 mm, giving a total extended length of approximately 322 mm.

The centre trunnion mount lets the SC40X180STC pivot to swing a diverter gate on a packaging conveyor, routing cartons between two lanes with sensor-confirmed end positions.
Delivers 1130 N of clamping force at 0.9 MPa for a light machining fixture. The magnetic piston enables CMSG sensors to verify the clamp is fully closed before the cycle starts.
Drives a pivoting linkage in a small component test stand. The adjustable cushioning protects the linkage and test sample from shock at the 180 mm stroke endpoints.
Select the SC40 bore when your application needs between roughly 500 N and 1000 N of push force at standard shop air. If your load is lighter, stepping down to the SC32 (402 N at 0.5 MPa) can reduce air consumption and physical size. For heavier loads, the SC50 provides 982 N at the same pressure.
This 180 mm stroke is well within the 1200 mm maximum standard stroke for the 40 mm bore. However, always check for side loads—a 16 mm rod can bend if the load is not guided. For strokes over 300 mm or any side-loading condition, use an external guide rail or a guided cylinder to protect the rod bearing. When replacing this cylinder, match all five key points: 40 mm bore, 180 mm stroke, PT port thread, centre trunnion (TC) mounting with the F-SC40TC bracket, and the built-in magnet (-S).
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 and is physically shorter than an ISO 15552 profile cylinder of the same bore and stroke, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC tie-rod cylinder with the same bore, stroke, PT ports, TC centre trunnion mount, and built-in magnet.
