About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X35
The AirTAC SC250X35 is a large-bore double-acting tie-rod cylinder delivering a substantial 24544 N of push force at 0.5 MPa (44178 N at the 0.9 MPa maximum operating pressure). With a 250 mm bore and a short 35 mm stroke, it is built for high-force clamping, pressing, or short-throw actuation in heavy industrial machinery.
This model features a 50 mm diameter piston rod with an M42x2 male thread and PT1" ports. The body length (A) measures 294 mm, giving a total extended length of approximately 329 mm. It includes an adjustable air cushion (40 mm length) to decelerate the high-mass piston, and operates on filtered air at 0.15-1.0 MPa within a -20 to +70 °C temperature range using standard TPU seals.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X35 Is Used
Heavy-Duty Pressing
Generates up to 44178 N of force at 0.9 MPa for short-stroke pressing, stamping, or forming operations in metal fabrication and assembly lines.
Industrial Clamping
The 35 mm stroke and high force output are ideal for securely clamping large workpieces or molds in CNC machining centers and injection molding machines.
Material Compaction
Used in waste management or recycling equipment to compact bulk materials where a powerful, short-throw linear actuator is required.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X35 the Right Cylinder?
For applications needing even higher force, consider stepping up to a larger bore if available, though the SC250 is already at the top of the standard SC range. If your force requirement is lower, the SC200 bore provides 15708 N push at 0.5 MPa, which may offer cost and space savings. Always ensure the mounting and rod alignment prevent side loading on the 50 mm rod.
To guarantee a correct replacement, match five key specifications: the 250 mm bore, the 35 mm stroke, the PT1" port thread, the basic (no bracket) mounting configuration, and the absence of a built-in magnet. This cylinder is a direct replacement for an existing AirTAC SC250X35 or a tie-rod cylinder with identical dimensions and porting.
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 SC250X35 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 increases to 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf.
No, the SC250X35 is a 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 under load. For load holding, you must use an external mechanical lock, a rod brake, or a pilot-operated check valve in the circuit.
