About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X50
The AirTAC SC250X50 is a large-bore double-acting tie-rod cylinder delivering a substantial push force of 24544 N at 0.5 MPa (up to 44178 N at 0.9 MPa). With a 50 mm rod and a short 50 mm stroke, this model provides a compact, high-force linear actuation package within the ISO 6430 class for heavy-duty industrial tasks.
This cylinder features a 294 mm body length (total extended length approx. 344 mm) and a 40 mm adjustable air cushion to decelerate the high inertial loads typical of this bore size. It uses PT1" ports and an M42x2 rod thread, operating reliably on filtered air from -20 to +70 °C with standard TPU seals.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X50 Is Used
Heavy Press Tool Actuation
Provides up to 44178 N of force at 0.9 MPa for short-stroke clamping, punching, or pressing operations in metal forming and assembly jigs.
Material Handling Pushers
Delivers a powerful 24544 N push at standard line pressure to transfer heavy pallets or bulk materials on gravity or powered roller conveyors.
Injection Molding Core Pulls
The compact 50 mm stroke and high force output are ideal for actuating large core pulls or ejector plates in heavy plastic injection molds.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X50 the Right Cylinder?
For applications requiring slightly less force, consider stepping down to the SC200 bore, which provides 15708 N push force at 0.5 MPa. The 50 mm stroke on this 250 mm bore is well within the standard range, ensuring a rigid assembly with minimal rod bearing stress. When replacing, match exactly: 250 mm bore, 50 mm stroke, PT1" port thread, basic mounting (no bracket), and no magnet.
Even with a short stroke, the substantial 50 mm rod diameter on the SC250X50 provides excellent resistance to side loading. However, for any application where a radial force is applied to the rod end, always use an external guide rail or rod-eye joint to prevent bending moments from reaching the piston rod bearing.
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 SC250X50 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 force at 1.0 MPa is 5006 kgf.
No. The SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder. The SC250 bore is built to an ISO 6430 class standard for tie-rod cylinders, not ISO 15552. It is a direct dimensional replacement only for another AirTAC SC250 cylinder of the same stroke and port configuration.
