About the Airtac SC100 Standard Cylinder SC100X450H
The AirTAC SC100X450H is a double-acting single-rod pneumatic cylinder built for high-temperature duty, with a 100 mm bore and 450 mm stroke. Its Viton (FKM) seals extend the operating range to 0–150 °C, making it suitable for autoclaves, foundries, and drying lines where standard seals would degrade.
At 0.5 MPa air pressure this cylinder generates 3927 N pushing force and 3681 N pulling force, rising to 7068 N push at 0.9 MPa. The 25 mm diameter piston rod, PT1/2 port thread, and 29 mm adjustable air cushion ensure reliable deceleration even under heavy loads. Body length A is 188 mm, giving a total extended length of approximately 638 mm.

Where the Airtac SC100 Standard Cylinder SC100X450H Is Used
High-Temperature Process Actuation
Viton seals allow continuous operation up to 150 °C. Ideal for autoclave door clamping, hot press ejection, and kiln damper actuation where heat would destroy standard TPU seals.
Heavy Press & Clamping
With 3927 N push at 0.5 MPa and 7068 N at 0.9 MPa, this cylinder handles heavy clamping, pressing, and forming operations. The 450 mm stroke provides ample daylight for part loading.
Material Handling & Lift Gates
The 100 mm bore delivers the force needed for lifting heavy bins or actuating transfer gates. The Viton seals add reliability in dusty or hot warehouse environments.
Is the Airtac SC100 Standard Cylinder SC100X450H the Right Cylinder?
Select the SC100 bore when your application needs roughly 3900–5500 N of push force at typical shop air (0.5–0.7 MPa). If you can accept less force, stepping down to an SC80 (2513 N at 0.5 MPa) saves space and air consumption. For strokes of 300 mm or more, always check side-load conditions — a 450 mm stroke with a 25 mm rod can experience bending stress if the load is not guided. Use an external guide rail or a guided cylinder when side forces are present.
To replace an existing SC100X450H, match five points: 100 mm bore, 450 mm stroke, PT1/2 port thread, basic mounting (no bracket), and Viton seal. The SC is a tie-rod cylinder, not an ISO 15552 profile unit, so dimensional interchangeability is limited to other AirTAC SC tie-rod cylinders of the same configuration.
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 SC100X450H FAQ
At 0.5 MPa the push force is 3927 N and 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 (approx. 7850 N).
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 cylinder of the same bore and stroke. The mounting dimensions and body length differ, so it is not a drop-in replacement. Only replace another AirTAC SC tie-rod cylinder with matching bore, stroke, port thread, and mounting.
