The AirTAC Airtac SC40 Standard Cylinder SC40X62STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 62mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X62STC is a double-acting single-rod pneumatic cylinder with a 40 mm bore and 62 mm stroke, delivering a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa. The 16 mm diameter piston rod and PT1/4 ports make it a compact yet robust actuator for medium-duty linear tasks.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and the TC centre trunnion mounting (supplied with TCM1 bracket, part F-SC40TC) allows the cylinder to pivot, ideal for swinging loads. The standard TPU seals provide reliable operation from -20 to +70 °C.

The 62 mm stroke and trunnion mount allow this cylinder to pivot, making it perfect for actuating diverter gates on packaging conveyors where sensor confirmation of position is required.
With 628 N of clamping force at 0.5 MPa and magnetic piston sensing, it ensures precise, verified clamping of workpieces in CNC machining and welding fixtures.
The combination of a short 62 mm stroke and trunnion pivot is ideal for repetitive push/pull tests or component pressing in automated assembly cells.
Choose the SC40 bore when your application needs around 628 N of push force at standard plant pressure. If you need more force, step up to the SC50 which provides 982 N at 0.5 MPa; for a lighter, more compact solution, the SC32 delivers 402 N. The 62 mm stroke is a standard length for this bore. For strokes over 300 mm on this rod size, consider an external guide to protect the 16 mm rod from side-load bending.
To replace this cylinder, match five points: 40 mm bore, 62 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting, and the built-in magnet for sensors. This tie-rod design is not an ISO 15552 drop-in; it is shorter and must be replaced with another AirTAC SC series cylinder.
Quick checklist
At 0.5 MPa (5 bar) air pressure, 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.
Yes. The 'S' in the model code indicates a built-in magnet in the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG reed or solid-state sensors directly onto the cylinder barrel to detect end-of-stroke position.
