About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X800S
The AirTAC SC200X800S is a large-bore double-acting tie-rod cylinder delivering a substantial push force of 15708 N at 0.5 MPa and up to 28274 N at the maximum operating pressure of 0.9 MPa. With an 800 mm stroke, it is well-suited for heavy-duty linear applications requiring significant power over a long travel distance.
This model features a 40 mm diameter piston rod with an M36x2 knuckle thread and PT3/4 ports. The built-in magnet (-S suffix) allows for direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for precise, non-contact position feedback. The adjustable air cushion, with a 33 mm cushion length, decelerates the piston smoothly at the end of the stroke to manage high inertial loads.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X800S Is Used
Heavy Pressing & Clamping
Generates up to 28274 N of force for large-scale pressing, clamping, and riveting operations in metal fabrication and assembly lines.
Material Handling Pushers
Provides the long 800 mm stroke needed to push heavy pallets, logs, or scrap material off a conveyor or sorting line.
Industrial Gate & Damper Actuation
Operates large hopper gates, diverter chutes, or ventilation dampers, with sensor feedback confirming the open/closed position.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X800S the Right Cylinder?
Select the SC200 bore when your application requires a push force between 15708 N and 28274 N. If the force requirement is slightly lower, stepping down to an SC160 bore provides 10053 N at 0.5 MPa, which may reduce energy consumption. For strokes of 800 mm, carefully evaluate side-loading conditions; a long, unsupported 40 mm rod can be subject to bending moments. Use an external guide rail or rod alignment coupler to prevent rod bearing damage and ensure seal longevity. For a direct replacement, match the 200 mm bore, 800 mm stroke, PT3/4 port thread, basic mounting, and the -S magnet option.
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 SC200X800S FAQ
At 0.5 MPa, 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.
Yes. The -S suffix in the model code SC200X800S indicates a built-in magnet in the piston. This allows you to clamp compatible CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel for end-of-stroke or mid-stroke position sensing.
