The AirTAC Airtac SC40 Standard Cylinder SC40X400SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 400mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X400SH is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 400 mm stroke suit medium-duty linear applications requiring high-temperature resistance.
This model features a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection. Viton (FKM) seals (-H suffix) shift the operating temperature range to 0–150 °C, making it ideal for autoclaves, foundries, or drying equipment where standard seals would degrade. The 16 mm diameter piston rod and 21 mm adjustable air cushion ensure smooth deceleration.

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 withstand 0–150 °C, making this cylinder suitable for autoclave doors, laminating presses, and drying oven conveyors where heat degrades standard seals.
The built-in magnet allows CMSG/DMSG sensors to confirm clamp position in automated welding fixtures or assembly cells, preventing cycle-start errors.
Actuates diverter gates on conveyors carrying warm or hot products, such as baked goods or heat-treated parts, with reliable position feedback via barrel-mounted sensors.
For applications needing more force, step up to the SC50 series, which provides 982 N at 0.5 MPa. If a shorter overall length is required, the SC40X300SH reduces the extended dimension. The 400 mm stroke on a 16 mm rod requires careful side-load management; for off-axis loads, use an external linear guide or switch to a guided cylinder to prevent rod bending and premature seal wear.
When replacing this cylinder, match five key points: 40 mm bore, 400 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the Viton seal material for high-temperature operation. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC40 cylinders.
Quick checklist
At 0.5 MPa, the push force is 628 N and pull force is 528 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The AirTAC 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. Replace only with another AirTAC SC40 cylinder matching the 400 mm stroke, PT ports, magnet option, and Viton seals.
