About the Airtac SC100 Standard Cylinder SC100X1200H
The AirTAC SC100X1200H is a double-acting single-rod tie-rod cylinder delivering a substantial 3927 N of push force at 0.5 MPa (7068 N at the maximum operating pressure of 0.9 MPa). With a 25 mm diameter piston rod and a 1200 mm stroke, this model is built for heavy linear applications requiring a long reach.
This variant is equipped with high-temperature Viton (FKM) seals, extending the operating temperature range to 0–150 °C, making it suitable for hot environments like autoclaves or foundries. The adjustable pneumatic cushion (29 mm) decelerates the piston smoothly at the end of its travel, protecting the end caps from impact.

Where the Airtac SC100 Standard Cylinder SC100X1200H Is Used
Hot Press Actuation
The Viton seals allow this cylinder to operate reliably in the 0-150°C range, making it ideal for actuating platens in hot presses, vulcanizing equipment, and heated laminating machines.
Long-Stroke Material Pusher
With a 1200 mm stroke and 3927 N of force at 0.5 MPa, it excels at pushing heavy pallets, logs, or large sheet materials across transfer tables and conveyor systems.
Foundry & Glass Machinery
The robust tie-rod construction and high-temperature seals handle the radiant heat and demanding duty cycles of foundry knock-out stations, glass forming lines, and autoclave door actuation.
Is the Airtac SC100 Standard Cylinder SC100X1200H the Right Cylinder?
For applications needing slightly less force, the 80 mm bore SC80 series provides 2513 N at 0.5 MPa. If your load exceeds 3927 N, stepping up to the 125 mm bore (6136 N at 0.5 MPa) is recommended. At a 1200 mm stroke, the piston rod is fully supported by the front bearing, but any significant side load will cause rod deflection and premature seal wear; an external linear guide or a guided cylinder is essential for off-axis loads.
To ensure a correct replacement, match five key points: the 100 mm bore, the 1200 mm stroke, the PT port thread, the basic (no bracket) mounting configuration, and the absence of a built-in magnet. This model's Viton seals also make it a direct replacement for other SC100X1200H cylinders in high-temperature service.
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 SC100X1200H 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 increases to 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. The SC100X1200H is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The adjustable air cushion only decelerates the piston at the stroke end to reduce impact; it is not a locking or holding device. For load holding, you must add an external rod lock or a pilot-operated check valve.
