About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1000S
The AirTAC SC250X1000S is a large-bore, double-acting tie-rod cylinder engineered for heavy industrial linear motion. With a 250 mm bore and 1000 mm stroke, it generates a substantial push force of 24544 N at 0.5 MPa and reaches a theoretical maximum of 44178 N at 0.9 MPa, making it suitable for pressing, lifting, and positioning large assemblies.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for non-contact position feedback. The robust 50 mm diameter piston rod and 40 mm adjustable air cushion provide smooth deceleration, while the PT1 inch port thread ensures high flow for responsive cycle times. The body length A is 294 mm, giving a total extended length of approximately 1294 mm.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1000S Is Used
Heavy Pressing & Assembly
Delivers up to 44 kN of force for pressing bearings, forming sheet metal, or assembling large structural components in automotive and heavy equipment manufacturing.
Material Handling & Lifting
Ideal for lifting and tilting heavy pallets or containers in logistics centers. The built-in magnet provides reliable end-of-stroke sensing to control vertical lift sequences safely.
Construction Machinery Actuation
Used in concrete molding and vibration tables where high force and a 1000 mm stroke are needed to move heavy molds. The tie-rod design allows for field maintenance in harsh environments.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1000S the Right Cylinder?
Choose the SC250 when your application requires forces in the 24 kN class at standard factory air pressure. For a step down in force, the SC200 bore provides 15708 N push at 0.5 MPa, while this 250 mm bore offers a significant 56% force increase for the most demanding tasks. As an ISO 6430 class cylinder, it is designed for heavy-duty service at speeds of 30-500 mm/s.
At a 1000 mm stroke, the 50 mm rod is robust, but always evaluate side-load conditions. If the load is not guided externally, side forces can create a bending moment on the rod bearing, leading to premature seal wear or rod damage. For a direct replacement, match the bore, stroke, PT thread, and the -S magnet option precisely to another AirTAC SC250 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 SC250X1000S FAQ
At the standard operating pressure of 0.5 MPa, the push force is 24544 N and the pull force is 23562 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf.
Yes. The -S suffix in the model code SC250X1000S indicates a built-in magnetic piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel's sensor groove to detect piston position without any additional brackets.
