About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X130S
The SC250X130S is a heavy-duty double-acting tie-rod cylinder delivering a substantial 24544 N push force at 0.5 MPa (44178 N at the 0.9 MPa maximum operating pressure). This model features a 130 mm stroke and a 50 mm diameter piston rod with M42x2 male knuckle threads, making it suitable for high-force clamping, pressing, and lifting tasks.
A built-in magnet (-S suffix) is factory-installed, allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for reliable end-of-stroke or mid-stroke position feedback. The cylinder uses adjustable air cushioning (40 mm cushion length) to decelerate the piston smoothly, and operates on standard filtered air with PT1 inch ports. Its body length A is 294 mm, resulting in a compact extended length of 424 mm.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X130S Is Used
Heavy Press Tool Actuation
Provides up to 44 kN of force at 0.9 MPa for operating forming dies, punch presses, and heavy assembly fixtures where consistent, high clamping pressure is critical.
Pallet Lifting & Transfer
The 130 mm stroke and 50 mm rigid rod handle vertical lifting of loaded pallets in material handling stations, with magnetic sensors confirming lift completion.
Steel Fabrication Jigs
Ideal for welding and fabrication jigs requiring robust, repetitive clamping of large steel sections, with sensor feedback integrated into automated weld sequences.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X130S the Right Cylinder?
Select the SC250 when your application requires forces in the 24.5 kN class at standard plant pressure. If your load is lighter, stepping down to the SC200 bore reduces push force to 15708 N at 0.5 MPa, saving space and air consumption. For strokes of 300 mm or more, always assess side-loading on the 50 mm rod—external linear guides or a guided cylinder configuration are recommended to prevent rod bending and premature bearing wear.
For a drop-in replacement, match five key attributes: 250 mm bore, 130 mm stroke, PT1 inch pneumatic ports, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting style. This SC model is a tie-rod cylinder with a shorter envelope than an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC250 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 SC250X130S FAQ
At 0.5 MPa (approx. 73 psi), the cylinder delivers a push force of 24544 N and a pull force of 23562 N. The maximum operating pressure of 1.0 MPa yields a theoretical push force of 5006 kgf. Always factor in a safety margin for dynamic loads.
Yes. The -S suffix in the model code SC250X130S indicates a built-in magnetic piston band. This allows you to clamp compatible AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel without any additional mounting brackets.
