The AirTAC Airtac SC40 Standard Cylinder SC40X610SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 610mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X610SH is a double-acting pneumatic cylinder delivering a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa operating pressure. Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration across the 610 mm stroke, making it suitable for medium-duty linear tasks that need consistent force and reliable cushioning.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection without external brackets. The -H suffix specifies Viton (FKM) seals, shifting the operating temperature range to 0 to +150 °C for hot or chemically aggressive environments. Ports are standard PT1/4.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
The Viton seals allow this cylinder to operate reliably in ambient temperatures up to 150°C, making it ideal for actuators near ovens, autoclaves, or heated press tooling.
The built-in magnetic piston enables CMSG/DMSG sensors to confirm gate position, providing closed-loop feedback for diverting packages or parts on conveyor lines.
Suitable for clean-in-place or steam-washdown environments where FKM seals resist aggressive cleaning agents and high-temperature sterilization cycles.
For applications requiring more force, stepping up to the 50 mm bore SC50 series provides 982 N of push at 0.5 MPa. If space is a constraint but less force is acceptable, the 32 mm bore delivers 402 N. At a 610 mm stroke, the 16 mm rod is susceptible to bending under side loads; use an external linear guide or a rod-alignment coupler to protect the rod bearing and extend seal life.
When replacing an existing cylinder, match five points: 40 mm bore, 610 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor compatibility, and the Viton seal material (-H) for high-temperature operation. This tie-rod design is dimensionally shorter than an ISO 15552 cylinder and is not a drop-in interchange for that standard.
Quick checklist
At 0.7 MPa operating pressure, the push force is 879 N and the pull force on the return stroke is 528 N. The maximum operating force at 0.9 MPa is 1130 N push.
Yes. The -S suffix indicates a magnet is built into the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the barrel to detect piston position without any modification.
