About the Airtac SC100 Standard Cylinder SC100X450SH
The AirTAC SC100X450SH is a double-acting single-rod tie-rod cylinder delivering 3927 N push force at 0.5 MPa and up to 7068 N at 0.9 MPa operating pressure. Its 100 mm bore, 25 mm rod, and 450 mm stroke suit medium-to-heavy linear actuation tasks where heat resistance is required.
This model carries the -S magnet suffix for direct mounting of CMSG/DMSG/EMSG sensors on the barrel, and the -H Viton (FKM) seal suffix, shifting the operating temperature range to 0–150°C. The 29 mm adjustable air cushion at each end decelerates the piston smoothly, while the PT1/2 port and M20x1.5 rod thread keep connections standard.

Where the Airtac SC100 Standard Cylinder SC100X450SH Is Used
Foundry & Heat-Treat Clamping
Viton seals allow the SC100X450SH to operate continuously at 150°C, making it suitable for clamping hot workpieces in foundries, glass plants, or heat-treatment lines where standard seals would degrade.
Heavy Press Guard Actuation
With 3927 N at 0.5 MPa and 7068 N at full pressure, this cylinder moves safety guards or heavy tooling slides on large presses. The built-in magnet enables end-of-stroke sensing for interlock confirmation.
High-Temperature Damper Control
Ideal for actuating dampers or diverter gates in hot exhaust or drying systems. The 450 mm stroke provides the travel needed for large ductwork, and Viton seals resist thermal cycling without hardening.
Is the Airtac SC100 Standard Cylinder SC100X450SH the Right Cylinder?
Choose the SC100 when the SC80's 2513 N push at 0.5 MPa is marginal—stepping up to the 100 mm bore adds over 1400 N of force without increasing pressure. For strokes of 450 mm, confirm that side loads are minimal or use an external guide; the 25 mm rod is robust, but long unsupported strokes can introduce bending moments under off-axis loads.
When replacing an existing cylinder, match five points: 100 mm bore, 450 mm stroke, PT1/2 port thread, the built-in magnet (-S), and the Viton seal (-H) for high-temperature compatibility. This SC tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.

- ✓ 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 SC100X450SH FAQ
At 0.5 MPa the push force is 3927 N and pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf (7850 N), but the cylinder is rated for 0.15–1.0 MPa operation.
No. The SC100X450SH is a double-acting cylinder and will drift or drop if air pressure is exhausted or the directional valve is centred. For load holding without live pressure, add a pilot-operated check valve, external rod lock, or mechanical brake—the adjustable air cushion only decelerates the piston at stroke end, it does not lock it.
