About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X450
The SC200X450 is a large-bore double-acting tie-rod cylinder delivering a substantial 15708 N of push force at 0.5 MPa and up to 28274 N at the maximum operating pressure of 0.9 MPa. With a 200 mm bore and a 450 mm stroke, this model is engineered for heavy-duty linear applications, featuring a 40 mm diameter piston rod and an M36x2 rod thread for robust end connections.
This cylinder includes a 33 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly, protecting the end caps from impact. The body length A is 244 mm, resulting in a total extended length of approximately 694 mm. The standard PT3/4 port threads ensure a reliable pneumatic connection for demanding industrial tasks.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X450 Is Used
Heavy Press & Forming
Provides the high force (up to 28274 N) needed for stamping, bending, or compacting materials in heavy manufacturing presses, where a 450 mm stroke accommodates deep-draw operations.
Large Valve Actuation
Operates high-torque quarter-turn valves or large gate valves in processing plants, using the robust 40 mm rod and M36x2 thread to handle significant stem loads over a long travel distance.
Timber & Log Handling
Positions heavy logs or lumber on sawmill carriages and conveyors, where the 200 mm bore provides the necessary thrust to move large masses and the tie-rod construction withstands harsh, dirty environments.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X450 the Right Cylinder?
Select the SC200 when your application requires a theoretical force of 3204 kgf at 1.0 MPa. If your load is lighter, stepping down to a 160 mm bore (SC160) provides 18095 N at 0.9 MPa, potentially reducing air consumption and physical size. For a 450 mm stroke, ensure the load is guided; a 40 mm rod extending nearly half a meter is vulnerable to bending under side loads. An external guide or a self-guided actuator is recommended to protect the rod bearing and seals.
For a direct replacement, match these five points: a 200 mm bore, 450 mm stroke, PT3/4 port thread, the specific mounting accessory (this is a basic body, order mounts like F-SC200LB or F-SC200TC separately), and the magnet option (this model has no built-in magnet). This ensures dimensional and functional interchangeability with an existing AirTAC SC200 tie-rod cylinder.
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 SC200X450 FAQ
At 0.7 MPa operating pressure, the SC200X450 double-acting cylinder produces a push force of 21991 N. The theoretical maximum force at 1.0 MPa is 3204 kgf. Always size the cylinder based on the force required at your specific working pressure.
No, it is not a direct drop-in replacement. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than a comparable ISO 15552 profile cylinder, so mounting dimensions and body length A (244 mm) will not match. It is a direct replacement only for another AirTAC SC200 tie-rod cylinder with matching bore, stroke, and port thread.
