About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X700
The AirTAC SC200X700 is a large-bore double-acting tie-rod cylinder designed for heavy industrial linear actuation. With a 200 mm bore and 700 mm stroke, it generates 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, making it a workhorse for high-force applications.
This model features a robust 40 mm diameter piston rod with an M36x2 knuckle thread and a PT3/4 port. The adjustable pneumatic cushion (33 mm length) decelerates the piston smoothly at each end of the stroke, reducing end-cap impact. The total body length A is 244 mm, and it operates within a standard temperature range of -20 to +70 °C using TPU seals.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X700 Is Used
Heavy Machinery Actuation
Provides the high thrust needed for lifting arms, booms, and material handling attachments on construction and agricultural equipment.
Large Press Tooling
Delivers up to 28274 N of force for clamping, pressing, and forming operations in heavy-gauge metal fabrication and composite molding presses.
Dock Leveler Positioning
Powers the hydraulic-like movement of large dock levelers and heavy-duty scissor lifts, offering reliable pneumatic control for industrial logistics.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X700 the Right Cylinder?
Select the SC200 when your application requires forces in the 15000-28000 N range. If your load is lighter, stepping down to an SC160 bore reduces the push force to 10053 N at 0.5 MPa, potentially saving on air consumption and space. For strokes of 700 mm, always assess side-loading conditions; a 40 mm rod extending this far is susceptible to bending under lateral forces. Use external linear guides or a guided cylinder if side loads are present.
For a direct replacement, match five key specifications: 200 mm bore, 700 mm stroke, PT3/4 port thread, basic (no bracket) mounting, and the absence of a built-in magnet. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC200X700 FAQ
At 0.7 MPa operating pressure, the SC200X700 double-acting cylinder produces a theoretical push force of 21991 N. The pull force on the retract stroke is 15080 N at 0.5 MPa, due to the area reduction from the 40 mm piston rod.
No. The SC200X700 is a standard double-acting cylinder and will not hold its position or a suspended load if air pressure is exhausted or the directional valve is centered. The adjustable cushion only decelerates the piston at stroke end. To hold a load safely, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
