About the Airtac SC40 Standard Cylinder SC40X200H
The SC40X200H is a double-acting pneumatic cylinder with a 40 mm bore and 200 mm stroke, built with high-temperature Viton (FKM) seals that extend the operating range to 0–150 °C. At a standard 0.5 MPa supply, it generates 628 N of push force and 528 N on the pull stroke, making it suitable for moderate clamping and transfer tasks in hot environments.
This model uses a 16 mm diameter piston rod with an M12x1.25 thread and PT1/4 ports. The adjustable air cushion at each end (21 mm length) decelerates the piston smoothly, and the tie-rod construction keeps the body length A compact at 142 mm, resulting in a total extended length of approximately 342 mm.

Where the Airtac SC40 Standard Cylinder SC40X200H Is Used
Autoclave & Sterilizer Actuation
Viton seals allow this cylinder to operate reliably in the 0–150 °C range, making it ideal for door lifts and tray transfers in steam sterilizers and autoclaves.
Hot Part Ejection
With 628 N of push force at 0.5 MPa, the SC40X200H ejects hot molded parts or die-cast components from tooling where ambient temperatures exceed standard seal limits.
Drying Oven Diverter
Use this 200 mm stroke cylinder to divert product lanes inside industrial drying ovens, where the Viton seals maintain integrity under continuous high-temperature exposure.
Is the Airtac SC40 Standard Cylinder SC40X200H the Right Cylinder?
Choose the SC40 bore when your application needs roughly 600–1100 N of force from a standard plant air supply. If you require more force, stepping up to the SC50 delivers 982 N push at 0.5 MPa; for a lighter, more compact solution, the SC32 provides 402 N. Always match the replacement cylinder on all five key points: bore, stroke, PT port thread, basic mount, and the absence of a magnet.
For this 200 mm stroke, the 16 mm rod is well-supported within the standard stroke range, but any side load should still be minimized with proper alignment. If the load is guided externally, the SC40X200H will operate reliably within its 30–800 mm/s speed range.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC40 Standard Cylinder SC40X200H FAQ
At 0.5 MPa (approx. 73 psi), the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 1280 N. The pull force is always lower because the rod reduces the effective piston area on the retract side.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than a comparable ISO 15552 profile cylinder, so mounting dimensions and body length A (142 mm) are not interchangeable. It is a direct replacement only for another AirTAC SC40 tie-rod cylinder with matching bore, stroke, PT ports, basic mount, and no magnet.
