The AirTAC Airtac SC40 Standard Cylinder SC40X220SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 220mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X220SH is a double-acting tie-rod cylinder delivering 628 N push force at 0.5 MPa (879 N at 0.7 MPa) from its 40 mm bore. With a 220 mm stroke and a 16 mm diameter piston rod, it suits medium-duty linear tasks where heat resistance is critical.
This model carries the -S magnet suffix for direct mounting of CMSG/DMSG/EMSG sensors on the barrel, plus the -H Viton (FKM) seal suffix. The FKM seals shift the operating temperature range to 0–150 °C, making the cylinder suitable for hot environments, foundry peripherals, or autoclave loading where standard TPU seals would degrade.

Specifications follow the official AirTAC SC series datasheet. Operating pressure 0.15–1.0 MPa, proof pressure 1.5 MPa, temperature −20 to +70 °C. Confirm against the product label before installation. Thread options: PT (standard) / G.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (approx.) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

| -S | Optional built-in magnet for sensor position sensing. |
Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
Viton seals allow continuous operation at up to 150 °C, making this cylinder ideal for furnace door openers, autoclave clamping, and hot-melt dispensing stations.
The built-in magnet supports CMSG/DMSG sensors for end-of-stroke detection, enabling closed-loop control in automated pick-and-place or pressing fixtures.
Use the SC40X220SH on conveyor diverters in baking or curing lines where ambient heat rules out standard cylinders. The 220 mm stroke handles wide lane sorting.
Choose the SC40 when 628 N at 0.5 MPa covers your load with a safety margin. If you need more force, step up to the SC50 (982 N at 0.5 MPa); for a lighter, more compact solution, the SC32 offers 402 N. The 220 mm stroke is within the 1200 mm maximum standard stroke for bore 40.
For a drop-in replacement, match five points: 40 mm bore, 220 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the Viton seal (-H). The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa the cylinder pushes with 628 N and pulls with 528 N. At 0.7 MPa push force rises to 879 N. The maximum operating pressure is 1.0 MPa, yielding a theoretical push of 128 kgf.
No. The SC series is a tie-rod cylinder and is shorter than an ISO 15552 cylinder of the same bore and stroke. It is not dimensionally interchangeable. Only replace another AirTAC SC tie-rod cylinder with matching bore, stroke, port thread, magnet option, and seal material.
