About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X100H
The SC200X100H is a large-bore double-acting pneumatic cylinder from the AirTAC SC tie-rod series, equipped with a 200 mm piston and a 100 mm standard stroke. This model generates a substantial push force of 15708 N at 0.5 MPa and can reach up to 28274 N at the maximum operating pressure of 0.9 MPa, making it suitable for heavy pressing and clamping tasks. The 40 mm diameter piston rod and 33 mm adjustable air cushion provide robust, controlled end-of-stroke deceleration.
This variant is specified with the 'H' suffix, indicating Viton (FKM) seals that shift the operating temperature range to 0 to +150 °C, ideal for hot or chemically aggressive environments. The body length (A) is 244 mm, resulting in a total extended length of approximately 344 mm. It features standard PT ports and does not include a built-in magnet, keeping the barrel profile clean for basic high-force actuation.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X100H Is Used
High-Temperature Foundry Actuation
The Viton seals allow this cylinder to operate reliably in ambient temperatures up to 150°C, making it suitable for clamping molds, moving ladles, or actuating dampers in foundries and heat-treatment facilities.
Heavy-Duty Compaction Presses
With a push force exceeding 28000 N at 0.9 MPa, the SC200X100H excels in waste compaction, baling, and material densification presses where a short, powerful stroke is required.
Industrial Autoclave Door Locks
The combination of high force output and high-temperature Viton seals makes this cylinder a reliable choice for locking and unlocking heavy autoclave or industrial oven doors during hot cycles.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X100H the Right Cylinder?
When sizing, the SC200 bore provides 15708 N of push force at 0.5 MPa. If your application requires slightly less force in a more compact package, consider stepping down to the 160 mm bore (10053 N at 0.5 MPa). For a direct replacement, ensure the alternative cylinder matches all five critical points: 200 mm bore, 100 mm stroke, PT port thread, basic (no bracket) mounting, and the absence of a magnet. The Viton seal material is critical for high-temperature compatibility.
For this 100 mm stroke, side-load bending moments on the 40 mm rod are minimal, but always ensure the load is guided externally if any lateral force is present to prevent premature rod bearing and seal wear.
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 SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X100H FAQ
At the standard 0.5 MPa operating pressure, the push force is 15708 N and the pull force is 15080 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 28274 N. The theoretical maximum force at 1.0 MPa is 3204 kgf.
No. As a standard double-acting cylinder, the SC200X100H will drift or drop if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at the end of the stroke to reduce impact. To hold a load safely without live pressure, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve.
