The AirTAC Airtac SC40 Standard Cylinder SC40X230STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 230mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X230STC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa), built around a 40 mm bore and 230 mm stroke. Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range automation tasks.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and ships with the TC centre trunnion mount plus TCM1 bracket (F-SC40TC), allowing the cylinder to pivot during operation. The PT1/4 port and TPU seals suit standard compressed-air systems operating from -20 to +70 °C.

The centre trunnion mount lets this cylinder pivot to actuate diverter gates on packaging conveyors, with sensor confirmation of gate position via the built-in magnet.
Delivers 1130 N of clamping force at 0.9 MPa for light staking, pressing, or holding fixtures in assembly cells, where the trunnion mount absorbs alignment shifts.
Operates discharge gates on small hoppers or chutes in agricultural processing, with the pivoting TC mount accommodating the arc of the gate linkage.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N push at 0.5 MPa. If space is tight and the load is lighter, the 32 mm bore SC32 series offers 402 N at the same pressure. Always match replacement cylinders on all five key points: 40 mm bore, 230 mm stroke, PT1/4 port thread, TC centre trunnion mounting with magnet, and tie-rod body style.
At a 230 mm stroke, the 16 mm rod is well-supported within standard limits, but avoid direct side loading. For guided motion, pair this cylinder with an external linear guide or consider a guided cylinder assembly if the load is offset from the rod axis.
Quick checklist
At the standard operating pressure of 0.5 MPa, this cylinder produces 628 N extending (push) and 528 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the extending force increases to 1130 N.
No, the SC series is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder, so it is not a drop-in interchange. It is a direct replacement only for another AirTAC SC40 tie-rod cylinder with matching bore, stroke, PT port, TC mount, and magnet sensor option.
