The AirTAC SC40 Standard Cylinder SC40X1150STCN 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 AirTAC SC40X1150STCN is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 1150 mm stroke suit long-reach linear tasks where a compact body is essential—the body length A is just 142 mm, keeping the retracted footprint short.
This model is factory-configured with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, a TC centre trunnion mount (supplied with TCM1 bracket, part F-SC40TC) for pivoting loads, and NBR (nitrile) seals. The 16 mm diameter rod and 21 mm adjustable air cushion provide smooth deceleration at end-of-stroke.

The 1150 mm stroke, combined with the pivoting TC trunnion mount, allows this cylinder to sweep parts between distant conveyor lines or workstations with a smooth, guided motion.
NBR seals and a built-in magnet for position sensing make this cylinder suitable for clamping and positioning in automated welding cells, where mid-stroke confirmation is required.
The long stroke and centre-pivot mounting enable a single cylinder to actuate a large diverter gate in agricultural handling equipment, directing material flow between silos or conveyors.
For applications needing a 40 mm bore, the SC40 delivers 628 N push at 0.5 MPa. If your load exceeds this, stepping up to the SC50 (982 N at 0.5 MPa) provides a 56% force increase. At 1150 mm stroke, the unsupported rod length is significant—side loads or off-centre mounting can cause rod bending. Consider an external linear guide or a guided cylinder if lateral forces are present. When replacing, match bore (40 mm), stroke (1150 mm), PT port thread, TC trunnion mount, and the -S magnet option exactly to ensure direct compatibility with an existing AirTAC SC tie-rod cylinder.
Quick checklist
At the standard operating pressure of 0.5 MPa, this 40 mm bore cylinder produces 628 N of push force and 528 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
For strokes exceeding 300 mm, especially with a 16 mm rod, side loading is a critical concern. The rod should be guided externally or the load supported on linear rails. Never use the cylinder rod itself as a guide; doing so will cause premature seal wear and potential rod bending.
