About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X900STC
The AirTAC SC250X900STC is a heavy-duty double-acting tie-rod cylinder engineered for high-force linear applications. With a 250 mm bore and 900 mm stroke, it generates a substantial 24544 N of push force at 0.5 MPa and up to 44178 N at 0.9 MPa, making it suitable for pressing, lifting, and large-scale material handling tasks.
This model features a built-in magnet (suffix S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (suffix TC) supplied with the TCM1 bracket for pivoting motion. The 50 mm diameter piston rod and 40 mm adjustable air cushion ensure robust performance and smooth deceleration at stroke ends. Operating pressure ranges from 0.15 to 1.0 MPa with a standard PT port thread.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X900STC Is Used
Heavy Pressing & Forming
Delivers up to 44178 N of force at 0.9 MPa for stamping, bending, or compression molding operations in metal and plastics processing.
Large-Scale Material Handling
The 900 mm stroke and pivoting trunnion mount are ideal for actuating large gates, diverters, or lift tables on heavy-duty conveyor systems.
Structural Testing Rigs
Provides controlled, high-force linear motion for load testing of beams, joints, and structural components, with sensor feedback enabled by the built-in magnet.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X900STC the Right Cylinder?
Select the SC250 bore when your application requires a push force between 24544 N (at 0.5 MPa) and 44178 N (at 0.9 MPa). If your force requirement is lower, consider stepping down to the SC200 bore, which provides 15708 N at 0.5 MPa. For even higher forces, confirm availability of larger custom solutions from the datasheet.
At a 900 mm stroke, the 50 mm rod is robust, but any significant side loading must be managed with an external guide rail or rod support to prevent bearing wear and rod bending. For a direct replacement, ensure the alternative cylinder matches this exact 250 mm bore, 900 mm stroke, PT port thread, centre trunnion (TC) mount, and built-in magnet configuration.

- ✓ 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 SC250X900STC 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 reaches 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf.
No. As a standard double-acting pneumatic cylinder, the SC250X900STC will drift or drop if air pressure is lost or the directional valve is centered. It does not have a mechanical lock. To hold a load safely, you must add an external rod brake, a pilot-operated check valve, or a separate mechanical locking mechanism.
