The AirTAC Airtac SC40 Standard Cylinder SC40X1150STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 1150mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X1150STC is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). With a 40 mm bore and 16 mm diameter piston rod, this model is built for linear applications that need a long 1150 mm working stroke without stepping up to a larger bore.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and ships with a centre trunnion (TC) pivot mount including the TCM1 bracket. The total extended body length is approximately 1292 mm, and the adjustable air cushion (21 mm) helps decelerate the load smoothly at end-of-stroke.

The 1150 mm stroke moves parts between distant conveyor stations. The centre trunnion mount lets the cylinder pivot as it extends, accommodating slight misalignment in transfer mechanisms.
Uses the full 1150 mm travel to divert packages on high-speed lines. The built-in magnet allows end-of-stroke confirmation via reed sensors, ensuring the gate is fully open or closed.
Operates long roof vents with a 628 N push. The TPU seals handle the -20 to +70 °C ambient range, and the trunnion mount allows the cylinder to follow the vent's arc without binding.
For applications requiring slightly more force, stepping up to the 50 mm bore provides 982 N at 0.5 MPa. At 1150 mm stroke, the 16 mm rod is extended significantly; ensure the load is guided externally to prevent rod bending or bearing side-load damage. If the motion involves pivoting, the included TC centre trunnion mount allows the cylinder to swing through an arc.
For a drop-in replacement, match these five points: 40 mm bore, 1150 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting with TCM1 bracket, and the built-in magnet (-S) for sensor compatibility. This is a tie-rod cylinder and does not interchange with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa the cylinder pushes with 628 N and pulls with 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.
A stroke of 1150 mm on a 16 mm rod creates a significant moment arm. Always use an external linear guide or rod-alignment coupler to absorb side loads. Never allow the rod to push a load that is not supported by rails or bearings, as side force will damage the rod bearing and seals.
