The AirTAC Airtac SC40 Standard Cylinder SC40X330SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 330mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X330SH is a double-acting pneumatic cylinder with a 40 mm bore and 330 mm stroke, delivering a push force of 628 N 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 model 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 high-temperature environments where standard seals would degrade.

With Viton seals rated for 0–150°C, this cylinder operates reliably in autoclaves, drying ovens, and foundry equipment where standard seals would fail.
The built-in magnet allows CMSG/DMSG sensors to confirm extend/retract position, ideal for diverting packages on a conveyor line with positive feedback to the PLC.
Generating 1130 N of thrust at 0.9 MPa, it provides consistent clamping force for gluing, welding, or light assembly presses requiring stroke-end confirmation.
Choose the SC40 bore for push forces around 628 N at 0.5 MPa. If your load requires more force, step up to the SC50 bore (982 N at 0.5 MPa); for a lighter, more compact solution, the SC32 bore offers 402 N. At 330 mm stroke, ensure the load is guided to prevent side-load bending on the 16 mm rod.
For a direct replacement, match these five points: 40 mm bore, 330 mm stroke, PT port thread, the built-in magnet (-S) for sensors, and the basic mounting configuration. This tie-rod cylinder is shorter than an ISO 15552 profile and is not a dimensional interchange.
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. The theoretical maximum at 1.0 MPa is 128 kgf.
A 330 mm stroke with a 16 mm rod is susceptible to bending under side loads. For any stroke over 300 mm, it is strongly recommended to use an external guide rail or rod-alignment coupler to protect the rod bearing and seals from premature wear.
