The AirTAC Airtac SC40 Standard Cylinder SC40X104 is a genuine double-acting standard air cylinder with a Ø40mm bore and 104mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X104 is a 40 mm bore, 104 mm stroke single-rod double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-stroke positioning tasks.
This tie-rod cylinder has a compact body length A of 142 mm and operates on filtered air from 0.15 to 1.0 MPa. Standard PT1/4 ports and an M12x1.25 rod thread simplify pneumatic connections. The TPU seals suit ambient temperatures from -20 to +70 °C.

Actuates a gate or diverter on a conveyor line, using the 104 mm stroke to push products onto a secondary lane with 628 N of force at 0.5 MPa.
Provides consistent clamping pressure for woodworking or light metal fabrication jigs, where the 16 mm rod and adjustable cushion ensure smooth, repeatable engagement.
Pushes cartons or packages into a case-packing station. The compact 142 mm body length plus 104 mm stroke fits easily into automated packaging cells.
Choose the SC40X104 when your application needs around 628 N of force at standard plant pressure. If you require more thrust, stepping up to a 50 mm bore (SC50) provides 982 N at the same 0.5 MPa. For lighter, faster cycles, a 32 mm bore (SC32) offers 402 N.
To replace an existing cylinder, match five points: 40 mm bore, 104 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and confirm whether a magnet is required. The SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.7 MPa operating pressure, the SC40X104 produces 879 N of push force and 528 N of pull force on the retract stroke, based on the official AirTAC thrust table for a 40 mm bore.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder of the same bore and stroke. It is not dimensionally interchangeable. Use it to replace another AirTAC SC tie-rod cylinder matching the same bore, stroke, port thread, and mounting.
