The AirTAC Airtac SC40 Standard Cylinder SC40X225SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 225mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X225SH is a 40 mm bore, 225 mm stroke tie-rod 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-range linear tasks.
This variant includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection. The -H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150 °C, making it suitable for hot environments where standard TPU seals would degrade.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
With Viton seals rated for 0–150°C, this cylinder is ideal for furnace doors, autoclave clamps, or hot stamping presses where standard seals would fail.
The built-in magnet allows CMSG/DMSG sensors to confirm extend and retract positions, perfect for pick-and-place units or automated assembly fixtures requiring cycle verification.
Delivering 628 N of push force, it can reliably actuate diverter gates on conveyor lines, directing products in packaging or logistics sorting systems.
Choose the SC40 for applications needing up to 628 N at standard plant pressure. If your load exceeds this, stepping up to the SC50 bore provides 982 N at the same 0.5 MPa. For strokes over 300 mm, consider an external guide to protect the 16 mm rod from side-load bending moments.
When replacing an existing unit, match five points: 40 mm bore, 225 mm stroke, PT port thread, the built-in magnet (-S) for sensor compatibility, and the Viton seal material for high-temperature operation.
Quick checklist
At 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 reaches 1130 N.
No. The SC series is a tie-rod cylinder with a shorter body length (A=142 mm) than an ISO 15552 profile cylinder of the same bore, so it is not dimensionally interchangeable. It replaces another AirTAC SC40 or a compatible tie-rod cylinder with matching bore, stroke, and port thread.
