The AirTAC Airtac SC40 Standard Cylinder SC40X75STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 75mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X75STC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa operating pressure. With a 40 mm bore and 75 mm stroke, it uses a 16 mm diameter piston rod with M12x1.25 male threads, making it a robust choice for medium-duty linear actuation tasks.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection. The TC centre trunnion mount (supplied with the TCM1 bracket, order code F-SC40TC) allows the cylinder to pivot, making it ideal for swinging loads. The compact tie-rod design features a body length of 142 mm and an adjustable air cushion to decelerate the piston smoothly.

The 75 mm stroke and centre trunnion mount allow this cylinder to pivot a diverter gate on a conveyor line, reliably sorting packages with its 628 N push force.
Ideal for swing-clamp mechanisms in machining centres. The built-in magnet confirms the clamp is fully engaged, while the trunnion mount accommodates the pivoting motion.
Provides a controlled 75 mm push stroke to index parts into an assembly station. The adjustable cushion reduces impact noise, and the sensor confirms retraction for the next cycle.
For applications needing more force, consider stepping up to the 50 mm bore SC50 series, which provides 982 N at 0.5 MPa. If lower force is acceptable, the 32 mm bore SC32 series offers 402 N. The 75 mm stroke is a standard length within the SC40's 1200 mm maximum range.
When replacing an existing cylinder, verify five key points: 40 mm bore, 75 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the built-in magnet for sensor compatibility. This ensures a direct dimensional and functional match with another AirTAC SC40 tie-rod cylinder.
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 reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No, the SC40X75STC is a double-acting cylinder and will not hold its position when air pressure is exhausted or lost. The piston can drift or drop. If load holding is required, you must add a pilot-operated check valve or an external mechanical rod lock.
