About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X75
The SC200X75 is a robust double-acting tie-rod cylinder delivering 15708 N of push force at 0.5 MPa, rising to 28274 N at the maximum operating pressure of 0.9 MPa. With a 200 mm bore and a short 75 mm stroke, this actuator is built for applications demanding immense force in a compact linear envelope.
This model features a 40 mm diameter piston rod with an M36x2 knuckle thread and PT3/4 ports. The total extended body length is approximately 319 mm, based on a 244 mm body length A plus the 75 mm stroke. Adjustable pneumatic cushioning decelerates the piston smoothly at both ends of the 33 mm cushion stroke.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X75 Is Used
Heavy Press Tool Actuation
Provides the high force needed for clamping, punching, or forming tools in a heavy industrial press, where a short, powerful stroke is essential.
Die Cushion Systems
Delivers controlled, high-force resistance or actuation within a stamping die cushion, utilizing the adjustable air cushion for smooth deceleration of the 40 mm rod.
Bulk Material Gate Control
Operates a heavy sliding gate or diverter valve for bulk materials, using the 15708 N force to reliably shear through and control the flow of dense aggregates.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X75 the Right Cylinder?
Select the SC200X75 when your application requires a force class around 15708 N at standard plant pressure. If your force requirement is lower, stepping down to a 160 mm bore reduces push force to 10053 N at 0.5 MPa, potentially saving space and air consumption. For a direct replacement, ensure the new cylinder matches this model's 200 mm bore, 75 mm stroke, PT3/4 port thread, basic mounting configuration, and the absence of a built-in magnet. This is a non-ISO 15552 tie-rod cylinder; interchangeability is limited to identical AirTAC SC200 units.
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 SC200X75 FAQ
At 0.7 MPa (7 bar) operating pressure, the theoretical push force output by this 200 mm bore cylinder is 21991 N. The maximum push force at the 0.9 MPa limit is 28274 N.
No. The SC200X75 is a standard double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The piston can drift or drop. To hold a load safely without live pressure, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve in the circuit.
