The AirTAC Airtac SC40 Standard Cylinder SC40X145STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 145mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X145STC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa) from its 40 mm bore. With a 145 mm stroke and a 16 mm diameter piston rod, it is well-suited for medium-duty clamping, pressing, and sorting tasks where a compact tie-rod design is preferred.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC) with the TCM1 bracket (F-SC40TC) for pivoting applications. The standard PT1/4 port and TPU seals provide reliable operation from -20 to +70 °C.

The 145 mm stroke and trunnion mount allow the cylinder to pivot as it extends, making it ideal for actuating diverter gates on packaging or assembly conveyors.
With 1130 N of force at 0.9 MPa, this cylinder provides secure clamping for CNC fixtures or welding jigs, with sensor confirmation of the clamped position.
The centre trunnion mount (TC) is designed for linkages that require the cylinder body to swing, such as bin tippers or machine guard actuators.
For higher force requirements, consider stepping up to the 50 mm bore SC50 series, which offers 982 N at 0.5 MPa. If a lower force with a smaller footprint is acceptable, the 32 mm bore provides 402 N. The 145 mm stroke is within the standard range for this bore.
To ensure a correct replacement, match five key points: 40 mm bore, 145 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting accessory, and the built-in magnet (-S) for sensor compatibility. Always verify the mounting bracket part code F-SC40TC.
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.
No. The SC series is a tie-rod cylinder, not an ISO 15552 profile cylinder. It is shorter than an ISO 15552 cylinder and is not dimensionally interchangeable. Use only AirTAC SC-specific mounting accessories like the F-SC40TC trunnion bracket supplied with this model.
