About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X500
The AirTAC SC250X500 is a large-bore double-acting tie-rod cylinder delivering 24544 N of push force at 0.5 MPa (44178 N at 0.9 MPa). Its 250 mm bore and 500 mm stroke suit heavy industrial linear actuation where substantial thrust is required.
This model features a 50 mm diameter piston rod with an M42x2 male thread and a PT1" supply port. The adjustable air cushion (40 mm length) decelerates the piston smoothly at stroke ends. The body length A is 294 mm, giving a total extended length of approximately 794 mm. As an ISO 6430 class cylinder, it is designed for robust, high-force applications.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X500 Is Used
Heavy Press & Forming
Provides the high clamping and pressing forces needed in hydraulic-press alternatives or heavy-gauge metal forming, using the 24544 N push at 0.5 MPa.
Large-Scale Material Handling
Powers pushers, lifters, and transfer carriages in steel mills or foundries, moving heavy loads with the robust 50 mm diameter piston rod.
Industrial Damper Actuation
Operates large dampers and diverter gates in heavy processing plants, where the 40 mm cushion absorbs kinetic energy from high-mass end-of-stroke impacts.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X500 the Right Cylinder?
Select the SC250X500 when your application demands force in the 24544 N class at standard plant pressure. If your load is lower, stepping down to the SC200 bore reduces push force to 15708 N at 0.5 MPa, potentially saving space and air consumption. For strokes of 300 mm or more, like this 500 mm unit, always evaluate side-loading: an unsupported 50 mm rod at full extension is vulnerable to bending under radial forces. Use an external linear guide or rod-alignment coupler to protect the rod bearing and seals.
For direct replacement, match five key points: 250 mm bore, 500 mm stroke, PT1" port thread, basic mount (no factory-fitted bracket), and no magnet. This ensures dimensional and performance interchangeability with another AirTAC SC tie-rod cylinder.
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 SC250X500 FAQ
At 0.5 MPa, push force is 24544 N and pull force is 23562 N. At the maximum operating pressure of 0.9 MPa, push force reaches 44178 N. The theoretical maximum at 1.0 MPa is 5006 kgf.
No. The SC series is a tie-rod cylinder conforming to ISO 6430 class for large bores, not ISO 15552. Its body length is shorter than an ISO 15552 cylinder of the same stroke, so mounting dimensions differ. Replace only with another AirTAC SC250 tie-rod cylinder matching the stroke, port, and mounting.
