About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X700S
The AirTAC SC250X700S is a large-bore double-acting tie-rod cylinder delivering 24544 N of push force at 0.5 MPa and up to 44178 N at 0.9 MPa. With a 50 mm diameter piston rod and PT1" ports, it handles heavy industrial actuation where substantial thrust is required.
This model features a 700 mm stroke, well within the 1500 mm maximum standard stroke for the 250 bore. The built-in magnet (suffix -S) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for reliable end-of-stroke detection. Total body length is approximately 994 mm.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X700S Is Used
Heavy Press Tool Actuation
Provides the high clamping and pressing forces needed in large hydraulic-style pneumatic press tools, with sensor feedback for cycle control.
Bulk Material Gate Control
Operates heavy slide gates on silos or hoppers, where the 24544 N push force easily manages dense material head loads.
Structural Test Rigs
Applies controlled, high-magnitude loads in civil or mechanical testing frames, with the magnet enabling precise stroke position data logging.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X700S the Right Cylinder?
When sizing, the 250 mm bore provides 24544 N push at 0.5 MPa. If your force requirement is lower, stepping down to a 200 mm bore reduces push force to 15708 N at the same pressure. For strokes of this length, ensure the load is guided externally if significant side forces are present, as the 50 mm rod is designed for axial thrust. To replace an existing unit, match bore, stroke, PT port thread, the -S magnet option, and basic mounting configuration exactly.
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 SC250X700S FAQ
At 0.5 MPa (5 bar) the cylinder pushes with 24544 N and pulls with 23562 N. At 0.7 MPa push force rises to 34361 N, and at the maximum operating pressure of 0.9 MPa it reaches 44178 N.
No. The SC250 is a double-acting cylinder and does not lock or hold position when air is exhausted or the valve centers. The piston will drift under load. For load holding, an external rod brake or pilot-operated check valve must be added to the circuit.
