About the Airtac SC100 Standard Cylinder SC100X400SH
The SC100X400SH is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa. With a 100 mm bore and a 400 mm stroke, this model features a 25 mm diameter piston rod and a 29 mm adjustable air cushion at each end to decelerate the piston smoothly.
This variant is equipped with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and Viton (FKM) seals (-H suffix) that shift the operating temperature range to 0 to +150 °C, making it suitable for high-temperature or aggressive environments. The body length A is 188 mm, giving a total extended length of approximately 588 mm.

Where the Airtac SC100 Standard Cylinder SC100X400SH Is Used
Hot Press Clamping
The Viton seals and 0-150°C rating allow this cylinder to operate reliably in heated platen presses for laminating or composite curing, where standard seals would degrade.
High-Temperature Gate Actuation
Controls diverters or stop gates on conveyor lines running through drying or baking ovens, with the magnet enabling precise end-of-stroke position feedback.
Heavy Part Ejection
Provides up to 7068 N of force at 0.9 MPa to eject large plastic or die-cast parts from hot molds, where the robust tie-rod construction handles repetitive impact.
Is the Airtac SC100 Standard Cylinder SC100X400SH the Right Cylinder?
For applications needing more force, stepping up to the SC125 bore provides 6136 N of push at 0.5 MPa. If a shorter, more compact footprint is acceptable, the SC80 bore offers 2513 N at the same pressure. With a 400 mm stroke, the 25 mm rod is well-supported within standard limits, but any significant side loading should be managed with an external linear guide to prevent rod bearing wear and bending. To replace an existing unit, match the 100 mm bore, 400 mm stroke, PT port thread, Viton seal material, and the integrated magnet for sensor compatibility.

- ✓ 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 SC100 Standard Cylinder SC100X400SH FAQ
At the standard 0.5 MPa operating pressure, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The SC100X400SH is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston will drift. For load holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
