About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X600H
The SC250X600H is a large-bore double-acting tie-rod cylinder engineered for heavy industrial force, delivering 24544 N push and 23562 N pull at 0.5 MPa (44178 N at the 0.9 MPa maximum operating pressure). Its 50 mm diameter piston rod and PT1" port supply the high flow needed for a 600 mm stroke, while the 40 mm adjustable air cushion at each end decelerates substantial moving masses smoothly.
This model is built with the H suffix Viton (FKM) seal package, extending the operating temperature range to 0–150 °C for hot environments. The body length A is 294 mm, giving a total extended length of approximately 894 mm. As a genuine AirTAC SC series cylinder, it is a shorter, non-ISO-15552 tie-rod design that fits where space is limited compared to a full-profile ISO cylinder.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X600H Is Used
Heavy Press & Forming
Clamping and forming jigs in hot environments up to 150°C, where the 44178 N push at 0.9 MPa and Viton seals withstand both force and temperature.
Large-Scale Material Handling
Pushing or lifting heavy steel billets and structural components on transfer lines, using the 24544 N push at 0.5 MPa for consistent, controlled motion.
Autoclave & Sterilisation Equipment
Actuating doors and clamps inside high-temperature sterilisation chambers, where the 0–150°C Viton seal range ensures reliable sealing without premature degradation.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X600H the Right Cylinder?
Select the SC250 when your application needs over 24 kN of push force at standard plant pressure. If your load is lighter, stepping down to the SC200 bore saves space and cost while still providing 15708 N push at 0.5 MPa. For strokes of 600 mm, the 50 mm rod has good column stiffness, but any significant side load requires an external linear guide or a guided cylinder to protect the rod bearing and seals from bending stress.
For a direct replacement, match five points: 250 mm bore, 600 mm stroke, PT port thread, basic mounting (no factory-fitted bracket), and no magnet. The H suffix means this unit uses Viton seals for high-temperature service; substituting a standard TPU seal cylinder would reduce the temperature ceiling to 70 °C.
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 SC250X600H FAQ
At 0.7 MPa operating pressure, the push force is 34361 N and the pull force is approximately 32987 N (calculated from the 23562 N pull at 0.5 MPa). The maximum push force at 0.9 MPa is 44178 N.
Yes, if the original cylinder had the same 250 mm bore, 600 mm stroke, PT1" port, and basic mounting. The H suffix upgrades the seals to Viton (FKM) for 0–150°C operation. If your application runs below 70°C, the standard TPU seal version (SC250X600) is also a direct dimensional match.
