About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X75H
The SC200X75H is a large-bore, double-acting tie-rod cylinder built for high-temperature duty. With Viton (FKM) seals, its operating range shifts to 0 to +150 °C, making it suitable for autoclaves, drying ovens, and hot-process actuation where standard seals would degrade. At 0.5 MPa air pressure, this 200 mm bore unit generates 15708 N of push force.
This model has a 75 mm stroke and a body length A of 244 mm. The 40 mm diameter piston rod provides robust resistance to bending, while the 33 mm adjustable air cushion at each end decelerates the high-inertia load smoothly. Ports are PT 3/4, and the rod thread is M36x2. The SC200X75H is a genuine AirTAC pneumatic cylinder.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X75H Is Used
Hot-Process Presses
Viton seals enable reliable actuation of laminating or curing presses operating continuously at elevated temperatures up to 150 °C.
Autoclave Door Actuation
The 15708 N push force at 0.5 MPa securely clamps autoclave or vulcanizing vessel doors in high-temperature sterilization and rubber-curing cycles.
Foundry & Glass Mould Clamping
Delivers consistent, high-force clamping for moulds in glass forming or die-casting peripherals, resisting heat soak from nearby molten materials.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X75H the Right Cylinder?
Choose the SC200X75H when a 160 mm bore's 10053 N push at 0.5 MPa is insufficient for the load. For lower force requirements, stepping down to an SC160 bore saves air consumption and physical space. Always match replacements across five points: 200 mm bore, 75 mm stroke, PT 3/4 port thread, basic (no bracket) mounting, and the high-temperature Viton seal material.
For strokes beyond 300 mm on this bore, side-load management becomes critical; an external guide rail or a guided cylinder configuration prevents rod-bearing bending and premature seal wear. The standard tie-rod design allows straightforward maintenance and seal-kit replacement.
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 SC200X75H FAQ
At 0.7 MPa supply pressure, the SC200X75H produces a theoretical push force of 21991 N. The pull force on the retract stroke is 15080 N at 0.5 MPa, accounting for the 40 mm rod area.
Yes, if the original is an AirTAC SC200 tie-rod cylinder. The 'H' suffix specifies Viton seals for 0 to +150 °C operation instead of the standard TPU seals. Ensure the port thread (PT 3/4), stroke, and mounting match. This cylinder does not include a magnet or mounting bracket.
