The AirTAC Airtac SC40 Standard Cylinder SC40X1015STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 1015mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X1015STC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa, scaling up to 1130 N at 0.9 MPa. With a 40 mm bore and a 16 mm diameter piston rod, this model is configured for a non-standard 1015 mm stroke, extending the total body length to approximately 1157 mm. The adjustable air cushion at both ends decelerates the piston across a 21 mm cushion length, protecting end caps during high-speed operation.
This unit includes a built-in magnet (suffix S), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the tie-rod barrel for precise position feedback. The TC suffix denotes a centre trunnion mount, supplied with the TCM1 bracket (part code F-SC40TC), which enables the cylinder to pivot for swinging or articulating load paths. Standard PT ports and TPU seals complete the configuration, rated for an operating pressure of 0.15–1.0 MPa and a temperature range of -20 to +70 °C.

The 1015 mm stroke is ideal for pushing or pulling products across wide conveyor gaps, where the centre trunnion mount allows the cylinder to pivot and follow the load path without binding.
The built-in magnet enables end-of-stroke sensing to confirm clamp position in automated welding cells, while the adjustable cushioning absorbs impact at high cycle rates.
Delivers the extended reach needed to separate and push pallets in automated storage systems, with the trunnion mount handling the inherent misalignment of heavy, shifting loads.
For applications requiring more force, stepping up to the SC50 series provides 982 N of push force at 0.5 MPa, while the SC32 offers a lighter 402 N alternative. This 1015 mm stroke exceeds the standard 1200 mm maximum for the 40 mm bore, making it a non-standard, made-to-order item. Given the extended stroke length, careful management of side loads is critical; the 16 mm rod is susceptible to bending under lateral forces, and an external linear guide or a guided cylinder configuration is strongly recommended to prevent rod bearing damage.
When replacing this cylinder, match five key attributes: the 40 mm bore, the exact 1015 mm stroke, the PT port thread, the centre trunnion (TC) mounting accessory, and the built-in magnet (-S) for sensor compatibility. This tie-rod design is dimensionally shorter than an ISO 15552 cylinder and is a direct replacement only for another AirTAC SC series unit with identical specifications.
Quick checklist
At the maximum operating pressure of 1.0 MPa, the theoretical push force is 1256 N. At the standard factory test pressure of 0.7 MPa, it delivers 879 N of push force, and at 0.5 MPa, it provides 628 N.
No. The AirTAC SC series is a tie-rod cylinder that is shorter than an ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 mounts. It is a direct drop-in replacement only for another AirTAC SC40 cylinder with the same bore, stroke, PT ports, TC mount, and magnet option.
