About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X175S
Delivering 24,544 N of push force at 0.5 MPa and up to 44,178 N at 0.9 MPa, the AirTAC SC250X175S handles extreme-force linear tasks with ease. This double-acting tie-rod cylinder features a 250 mm bore, a 175 mm stroke, and a robust 50 mm diameter piston rod with M42x2 male threads. The built-in magnet (-S suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for precise end-of-stroke or mid-position detection.
With a 40 mm adjustable air cushion and a compact body length A of 294 mm, this ISO 6430 class cylinder decelerates heavy loads smoothly at stroke ends. The standard PT1" port supplies ample flow for the 30-500 mm/s speed range. Operating on filtered air from 0.15 to 1.0 MPa, the SC250X175S is a genuine AirTAC power cylinder built for demanding factory automation.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X175S Is Used
Heavy Gantry Positioning
The 24.5 kN push force at 0.5 MPa moves large welding gantries or overhead manipulators with authority, while the magnet sensors confirm home and extended positions.
Hydraulic-Press Alternatives
Replace small hydraulic cylinders in clean environments. The SC250X175S delivers over 44 kN at 0.9 MPa for pressing bearings, bushings, or forming light-gauge metal.
Pallet Transfer Systems
Shift fully loaded heavy pallets across roller beds. The adjustable cushion absorbs the kinetic energy of a 1-tonne+ load, preventing shock transfer to the frame.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X175S the Right Cylinder?
Step up to this 250 mm bore when a 200 mm cylinder's 15,708 N push at 0.5 MPa is insufficient for your heavy-duty press or clamp. The 50 mm rod resists buckling, but at 175 mm stroke side loads are minimal. For longer strokes, always guide the load externally to protect the rod bearing. To replace an existing cylinder, match these five points exactly: 250 mm bore, 175 mm stroke, PT1" ports, built-in magnet for sensors, and the tie-rod SC body style. This model ships with TPU seals and PT threads as standard.

- ✓ 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 SC250X175S FAQ
At 0.5 MPa, push force is 24,544 N and pull force is 23,562 N. At the maximum operating pressure of 0.9 MPa, push force reaches 44,178 N. The theoretical maximum at 1.0 MPa is 5,006 kgf.
Yes. The -S suffix indicates a built-in magnet on the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rod slots without additional brackets.
