About the Airtac SC100 Standard Cylinder SC100X400H
The SC100X400H is a double-acting tie-rod cylinder with a 100 mm bore and 400 mm stroke, fitted with Viton (FKM) seals that shift the operating temperature window to 0–150 °C. At 0.5 MPa it delivers 3927 N push and 3681 N pull, while at the maximum operating pressure of 0.9 MPa the push force reaches 7068 N — enough for heavy pressing, clamping, and lifting tasks in hot environments.
This model uses a 25 mm diameter piston rod with an M20×1.5 male thread and PT 1/2 ports. The adjustable air cushion (29 mm length) decelerates the 400 mm stroke smoothly, and the total extended body length is approximately 588 mm (A=188 mm + stroke). The SC100X400H is a genuine AirTAC cylinder built for high-temperature duty where standard TPU seals would degrade.

Where the Airtac SC100 Standard Cylinder SC100X400H Is Used
High-Temperature Pressing
Viton seals allow continuous operation up to 150 °C, making the SC100X400H ideal for press tools, autoclave actuators, and mould-clamping cylinders near ovens or heated platens.
Heavy Part Ejection
With 7068 N of push at 0.9 MPa, this 400 mm stroke cylinder ejects large castings, stampings, or injection-moulded parts from tooling where heat is present.
Hot-Stamping & Forming
The 100 mm bore provides the force stability needed for hot-forming dies. The adjustable cushion protects the tooling by softening end-of-stroke impact at 400 mm travel.
Is the Airtac SC100 Standard Cylinder SC100X400H the Right Cylinder?
Choose the SC100 when your application needs roughly 4000 N of push at standard shop air. If the load is lighter, stepping down to an 80 mm bore (2513 N at 0.5 MPa) saves air and space; for heavier work the 125 mm bore delivers 6136 N at the same pressure. At 400 mm stroke the 25 mm rod is robust, but if the load applies any side force, add an external guide or linear rail — tie-rod cylinders are not designed to absorb bending moments, and a bent rod will damage the front bushing and seals.
For a drop-in replacement, match five points: 100 mm bore, 400 mm stroke, PT 1/2 ports, basic mounting (no bracket), and the -H Viton seal suffix. The SC is a tie-rod cylinder and is shorter than an ISO 15552 profile, so do not substitute an ISO 15552 cylinder without checking end-to-end dimensions.
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 SC100 Standard Cylinder SC100X400H FAQ
At 0.5 MPa the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa push rises to 5497 N, and at the maximum operating pressure of 0.9 MPa it reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf. All values assume clean, filtered air at 40 µm.
Not directly. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than a typical ISO 15552 profile cylinder of the same bore and stroke. Mounting hole patterns and body dimensions differ. Only substitute another AirTAC SC tie-rod cylinder with matching bore, stroke, PT 1/2 ports, and Viton seals to guarantee fit.
