The AirTAC Airtac SC40 Standard Cylinder SC40X800STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 800mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X800STC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 800 mm stroke suit mid-range linear tasks where a compact tie-rod body is preferred. The 16 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, plus a centre trunnion (TC) mount with the TCM1 bracket for pivoting applications. The body length A is 142 mm, giving a total extended length of approximately 942 mm. Seals are standard TPU for -20 to +70 °C operation with PT ports.

The 800 mm stroke and centre trunnion mount allow the cylinder to pivot as it diverts packages or materials on conveyor lines, with sensor confirmation of gate position.
Delivers 1130 N at 0.9 MPa for secure workpiece clamping in CNC or assembly jigs. The magnetic piston enables end-of-stroke sensing for automated cycle start.
Pivots large ventilation or greenhouse louvres with a smooth 800 mm linear action. The trunnion mount handles the arcing motion, while sensors confirm open/closed status.
Choose the SC40 when your application needs around 628 N at 0.5 MPa. If you require more force, step up to the SC50 (982 N at 0.5 MPa); for a lighter, more compact solution, the SC32 offers 402 N. At 800 mm stroke, ensure the rod is guided externally if side loads are present—long, unsupported rods can bend under lateral force.
For a direct replacement, match five points: 40 mm bore, 800 mm stroke, PT port thread, centre trunnion (TC) mount with F-SC40TC bracket, and the built-in magnet for sensor compatibility. This cylinder is not dimensionally interchangeable with ISO 15552 profiles.
Quick checklist
At 0.5 MPa, the push force is 628 N and pull force is 528 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is shorter than an ISO 15552 cylinder, so mounting dimensions and body length differ. Only replace another AirTAC SC cylinder with matching bore, stroke, port thread, mounting, and magnet option.
