The AirTAC Airtac SC40 Standard Cylinder SC40X35SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 35mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X35SH is a double-acting single-rod pneumatic cylinder with a 40 mm bore and a 35 mm stroke, 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 end-of-stroke deceleration for light to medium automation tasks.
This model is factory-equipped with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise position feedback without external brackets. The -H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150 °C for hot or chemically aggressive environments.

Viton seals allow this cylinder to operate continuously in ovens, autoclaves, or sterilisation equipment where ambient temperatures reach up to 150 °C.
The built-in magnet supports CMSG/DMSG sensors for end-of-stroke detection in pick-and-place units, ensuring every cycle is confirmed in automated assembly cells.
Ideal for ejecting hot-moulded parts or diverting items on conveyors passing through curing ovens, where standard seals would degrade.
Choose the SC40 bore for push forces up to 628 N at 0.5 MPa; step up to the SC50 (982 N at 0.5 MPa) if your load requires more thrust. For this 35 mm stroke, side loading is minimal, but always align the rod with the load axis to prevent premature seal wear. When replacing an existing cylinder, match five points: 40 mm bore, 35 mm stroke, PT port thread, the built-in magnet (-S), and the Viton seal material.
Quick checklist
At 0.5 MPa the cylinder pushes with 628 N and pulls with 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.
Yes, the SC40X35SH is dimensionally identical to the SC40X35 but adds a built-in magnet and Viton seals. It fits the same mounting accessories and has the same PT1/4 port thread. Ensure your application can accept the 0–150 °C seal temperature range.
