The AirTAC Airtac SC40 Standard Cylinder SC40X375STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 375mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X375STC is a 40 mm bore double-acting tie-rod cylinder delivering a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa. With a 375 mm stroke and a 16 mm diameter piston rod, this model is well-suited for medium-reach clamping, pressing, and material-transfer tasks where consistent pneumatic power is required.
This configuration includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the barrel, and a centre trunnion mount (TC, supplied with TCM1 bracket, accessory code F-SC40TC) for pivoting applications. The adjustable air cushion (21 mm) decelerates the piston smoothly at end-of-stroke, reducing impact noise and vibration.

The 375 mm stroke and centre trunnion mount allow this cylinder to swing a diverter gate on a conveyor line, routing products between lanes with a push force of 628 N at standard line pressure.
Used in a welding or assembly fixture where the cylinder body pivots on the TC mount. The built-in magnet enables end-of-stroke sensing to confirm the clamp is fully engaged before the cycle continues.
Applies a controlled 1130 N force at 0.9 MPa in a component durability test stand. The adjustable cushion protects the test sample and fixture from impact damage at the end of each cycle.
Choose the SC40X375STC when your application needs a 40 mm bore with a 375 mm stroke and pivoting movement. The centre trunnion mount allows the cylinder to swing, making it ideal for applications where the load path changes angle. For higher force requirements, consider stepping up to the 50 mm bore (SC50 series), which provides 982 N of push force at 0.5 MPa.
At a 375 mm stroke, ensure the rod is protected from side loads; external guides or a guided cylinder should be used if the load is not perfectly axial. For direct replacement, match the 40 mm bore, 375 mm stroke, PT port thread, TC mounting, and built-in magnet. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard operating pressure of 0.5 MPa, 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 increases to 1130 N. These values are for a double-acting cylinder with a 16 mm rod.
No. The SC40X375STC is a double-acting cylinder and will drift or drop if air pressure is lost or the directional valve is centered. To hold a load or position without live pressure, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve.
