About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X35S
The SC250X35S is a large-bore double-acting tie-rod cylinder delivering 24544 N of push force at 0.5 MPa, rising to 44178 N at the maximum operating pressure of 0.9 MPa. Its 35 mm stroke is well within the 1500 mm maximum standard stroke for the 250 mm bore, making this a compact yet immensely powerful actuator for short-throw, high-force clamping and pressing tasks.
This model features a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for reliable end-of-stroke detection. The rod diameter is 50 mm with an M42x2 thread, and the adjustable air cushion (40 mm length) decelerates the piston smoothly. Ports are PT 1 inch, and the standard TPU seals suit operating temperatures from -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X35S Is Used
Heavy-Duty Pressing
Generates up to 44178 N of force at 0.9 MPa for short-stroke pressing, staking, or forming operations in industrial manufacturing cells.
Automated Clamping
The 35 mm stroke and built-in magnet sensors provide precise, sensor-verified clamping of large workpieces on CNC machining centres or welding fixtures.
Material Handling Gates
Delivers rapid, high-force actuation for diverter gates or stops on heavy-duty conveyor systems, with sensor feedback confirming the gate position.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X35S the Right Cylinder?
For applications requiring slightly less force, the 200 mm bore SC200 series provides 15708 N of push force at 0.5 MPa. Stepping up to this 250 mm bore nearly doubles the available thrust. When replacing an existing cylinder, match five key points: bore (250 mm), stroke (35 mm), PT port thread, the built-in magnet (-S), and the basic mounting style. For this short 35 mm stroke, side-load and rod-bearing bending moments are minimal, but any external guidance should still be verified if the load is not purely axial.
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 SC250X35S FAQ
At the standard 0.5 MPa operating pressure, 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.
Ensure the replacement matches these five specifications: a 250 mm bore, a 35 mm stroke, PT 1 inch ports, a built-in magnet for sensors, and a basic (no bracket) mounting style. This is a tie-rod cylinder, not an ISO 15552 profile, so check the body length (A=294 mm) and mounting hole dimensions against your current unit.
