About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X200CA
The SC250X200CA is a large-bore double-acting pneumatic cylinder delivering a substantial 24544 N push force at 0.5 MPa (44178 N at the 0.9 MPa maximum operating pressure). With a 200 mm stroke and a 50 mm diameter piston rod, it is engineered for heavy industrial linear motion where high force is the primary requirement.
This model features a rear single clevis (CA) mount, allowing the cylinder body to pivot during operation, which is essential for applications with angular movement. The adjustable air cushion (40 mm length) decelerates the massive piston smoothly at end-of-stroke, protecting the end caps. Its body length A is 294 mm, giving a total extended length of approximately 494 mm.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X200CA Is Used
Heavy Press & Forming
Provides the high clamping and pressing forces needed for hydraulic-press alternatives in metal forming, stamping, and composite molding operations.
Large Valve Actuation
Ideal for automating high-torque butterfly or ball valves in water treatment and process industries, where the rear clevis mount accommodates the valve's arc of motion.
Material Handling Lift
Powers heavy-duty lifting and tipping mechanisms for large bins, hoppers, or construction material handling systems requiring a pivoting cylinder mount.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X200CA the Right Cylinder?
Select the SC250 when your application demands forces in the 24 kN class at standard plant pressure. If your load calculation falls closer to the 15 kN range, stepping down to a 200 mm bore (15708 N push at 0.5 MPa) can reduce air consumption and physical footprint. For strokes of 300 mm or more, always evaluate side-loading on the 50 mm rod; an external guide or a guided cylinder is strongly recommended to prevent rod bearing damage and ensure linear accuracy.
To replace an existing cylinder, match five points: 250 mm bore, 200 mm stroke, PT port thread (1 inch), rear clevis mounting (F-SC250CA), and the absence of a magnet. This SC is a tie-rod design, shorter than an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC tie-rod cylinders of the same configuration.
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 SC250X200CA FAQ
At 0.5 MPa, 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 at 1.0 MPa is 5006 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder of the same bore and stroke. It will not drop into an ISO 15552 footprint. It is a direct replacement only for another AirTAC SC250 tie-rod cylinder with matching bore, stroke, PT port, and rear clevis mount.
