About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X30S
The AirTAC SC250X30S is a heavy-duty double-acting tie-rod cylinder engineered for applications demanding immense force within a very short stroke. With a 250 mm bore, it generates a push force of 24544 N at 0.5 MPa, scaling up to a formidable 44178 N at the maximum operating pressure of 0.9 MPa. The 30 mm stroke is ideal for clamping, pressing, or ejector functions where high tonnage is required over a minimal travel distance.
This model features a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for precise, non-contact position sensing. The piston rod measures 50 mm in diameter with an M42x2 knuckle thread, providing robust resistance to bending. It operates on filtered air via a PT1 inch port, with an adjustable air cushion (40 mm length) to decelerate the substantial end-of-stroke inertia smoothly.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X30S Is Used
Heavy-Duty Clamping
Delivers up to 44178 N of force at 0.9 MPa for secure workpiece holding in large-scale welding fixtures and machining centers.
Short-Stroke Pressing
Ideal for bearing insertion, riveting, or stamping operations where a high-force, 30 mm linear push is precisely controlled and sensed.
Automated Ejection
Provides a powerful, sensor-verified ejection stroke for releasing heavy parts from large injection molds or forming dies.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X30S the Right Cylinder?
Select the SC250 bore when your application requires push forces exceeding 18095 N, which is the maximum thrust of the smaller SC160 at 0.9 MPa. If your force requirement is below 10053 N at 0.5 MPa, stepping down to an SC160 will reduce air consumption and physical footprint. For this 30 mm stroke, side loading is generally not a primary concern due to the short extension, but always ensure the load is guided externally if any radial force is present.
To replace an existing cylinder, verify these five points: a 250 mm bore, a 30 mm stroke, a PT1 inch port thread, a built-in magnet for sensor compatibility, and a basic (no bracket) mounting configuration. This SC model is a tie-rod cylinder and is dimensionally shorter than a standard ISO 15552 profile, so it is not a direct drop-in replacement for those types.
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 SC250X30S FAQ
The theoretical push force at 0.5 MPa is 24544 N, and the pull force is 23562 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 44178 N. The maximum theoretical force at 1.0 MPa is 5006 kgf.
Yes. The -S suffix in the model code SC250X30S indicates a built-in magnet is integrated into the piston. This allows you to clamp compatible AirTAC CMSG, DMSG, or EMSG sensors directly onto the cylinder barrel's tie-rod slots to detect piston position without additional brackets.
