About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X476S
The SC200X476S is a large-bore double-acting tie-rod cylinder delivering substantial push force of 15708 N at 0.5 MPa and up to 28274 N at the maximum operating pressure of 0.9 MPa. With a 200 mm bore, 40 mm piston rod, and PT1/2 ports, this actuator is built for heavy industrial tasks requiring a 476 mm linear stroke.
This model features a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for precise end-of-stroke or mid-stroke position feedback. The adjustable pneumatic cushion at each end (33 mm cushion length) decelerates the piston smoothly, protecting the end caps during high-cycle operation. Its body length A is 244 mm, giving a total extended length of approximately 720 mm.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X476S Is Used
Heavy Conveyor Gates
Operates large diverter gates or chutes in mining and aggregate handling, where the 15708 N push force moves heavy material flows reliably.
Press-Fit Assembly
Delivers controlled force for pressing large bearings, bushings, or structural pins into heavy fabrications with sensor-confirmed stroke completion.
Dock Leveler Actuation
Powers hydraulic-free dock levelers or lifting platforms, using the magnet for integrated position sensing in logistics hubs.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X476S the Right Cylinder?
For applications needing slightly less force, stepping down to a 160 mm bore reduces push force to 10053 N at 0.5 MPa. If your load requires even higher thrust, the 250 mm bore SC series provides 24544 N at the same pressure. Always match replacement cylinders on all five key points: bore (200 mm), stroke (476 mm), PT port thread, the built-in magnet (-S), and the basic mounting configuration.
At a 476 mm stroke with a 40 mm rod, ensure the load is guided externally if any side forces are present. Long unsupported strokes can impose bending moments on the rod bearing; using an external guide rail or rod-alignment coupler prevents premature seal wear and maintains smooth operation.
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 SC200X476S FAQ
At 0.5 MPa air pressure, the cylinder produces 15708 N pushing and 15080 N pulling. At the maximum operating pressure of 0.9 MPa, the push force increases to 28274 N. The theoretical maximum force at 1.0 MPa is 3204 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston, so AirTAC CMSG, DMSG, or EMSG sensors clamp directly onto the tie-rod barrel without additional brackets.
