The AirTAC Airtac SC40 Standard Cylinder SC40X700SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 700mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X700SH is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa) from its 40 mm bore. With a 700 mm stroke and a 16 mm diameter piston rod, it suits medium-reach linear tasks where heat resistance is critical.
This model features a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors and Viton seals (-H suffix) that shift the operating temperature range to 0 to +150 °C. The tie-rod construction keeps the body length to a compact 142 mm plus stroke, with PT1/4 ports and an adjustable air cushion of 21 mm at each end.

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 this cylinder to operate continuously in ambient temperatures up to 150 °C, making it suitable for pressing, drying, or autoclave door actuation where standard seals would fail.
The built-in magnet accepts CMSG/DMSG sensors for end-of-stroke detection, enabling precise sequence control in automated clamping or assembly fixtures with a 700 mm reach.
With 628 N of push force at 0.5 MPa, this cylinder can transfer parts across a 700 mm span on packaging or sorting lines, provided the load is guided to protect the rod.
For higher force at the same pressure, step up to the 50 mm bore SC50 series, which provides 982 N at 0.5 MPa. If a shorter, cooler-running cylinder is sufficient, the 32 mm bore SC32 offers 402 N at 0.5 MPa. At a 700 mm stroke, the 16 mm rod is susceptible to bending under side loads; use an external linear guide or a guided cylinder if the load is not purely axial.
To replace this cylinder, match five points: 40 mm bore, 700 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the Viton seal material for high-temperature compatibility. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profiles.
Quick checklist
At 0.7 MPa supply pressure, the 40 mm bore generates 879 N of push force and 528 N of pull force on the retract stroke, based on the official AirTAC thrust table.
Yes. The -S suffix in SC40X700SH indicates a built-in magnet inside the piston, so CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the barrel for contactless position sensing.
