The AirTAC Airtac SC40 Standard Cylinder SC40X320SFA is a genuine double-acting standard air cylinder with a Ø40mm bore and 320mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X320SFA is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore houses a 16 mm diameter piston rod with M12x1.25 male threads, and the 320 mm stroke suits medium-reach clamping, lifting, and material-transfer tasks.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, plus a front rectangular flange (FA, part F-SC40FA) for rigid panel mounting. The adjustable air cushion at each end decelerates the piston over the final 21 mm of travel, reducing end-cap impact. Ports are PT1/4 with a standard TPU seal for operation from -20 to +70 °C.

The FA front flange allows direct mounting to a machine bulkhead for pressing, staking, or riveting operations where the 628 N force at 0.5 MPa provides consistent pressure.
With a 320 mm stroke and magnetic piston for end-of-stroke sensing, this cylinder is ideal for pushing or lifting parts between conveyor lanes or indexing stations.
Use the SC40X320SFA to operate diverters or stop gates on packaging lines. The sensor-ready design confirms gate position, while the adjustable cushion ensures quiet, low-impact cycling.
For higher force at the same pressure, step up to the 50 mm bore SC50 series (982 N push at 0.5 MPa). If space is tight and lower force is acceptable, the 32 mm bore SC32 provides 402 N. At 320 mm of stroke, ensure the rod is not subjected to significant side load; an external linear guide or a guided cylinder is recommended to protect the rod bearing and seals from bending stress.
To replace an existing unit, match five points: 40 mm bore, 320 mm stroke, PT1/4 port thread, the FA front flange mounting accessory, and the built-in magnet (-S) for sensor compatibility. 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 cylinder produces 628 N extending (push) and 528 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. Match it against another AirTAC SC tie-rod cylinder of the same bore, stroke, port thread, mounting, and magnet option.
