About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X20S
The SC250X20S is a double-acting single-rod pneumatic cylinder delivering 24544 N of push force at 0.5 MPa (44178 N at the 0.9 MPa maximum operating pressure). With a 250 mm bore and a short 20 mm stroke, it is built for applications that need immense clamping or pressing power within a very compact linear travel.
This model includes the -S suffix, meaning a built-in magnet is fitted on the piston. You can mount CMSG, DMSG, or EMSG reed or solid-state sensors directly onto the tie-rod barrel for non-contact position feedback. The rod is 50 mm diameter with an M42x2 knuckle thread, and the total extended body length is approximately 314 mm (A=294 mm + 20 mm stroke). Ports are PT1".

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X20S Is Used
Heavy-Duty Clamping
Generates up to 44178 N at 0.9 MPa to lock welding fixtures or assembly jigs with a brief 20 mm stroke, ensuring zero part movement during fabrication.
Press-Fit Insertion
Delivers controlled, high-force insertion for bearings or bushings. The built-in magnet (-S) allows sensor confirmation of full extension at the critical 20 mm depth.
Short-Throw Ejector
Pushes heavy components off a conveyor line with a fast 20 mm punch. The 50 mm rod withstands the impact, and the adjustable air cushion softens the end-of-stroke shock.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X20S the Right Cylinder?
Choose the SC250 bore when your application demands over 24000 N of force at standard plant pressure. If your load is lighter, stepping down to the SC200 bore (15708 N push at 0.5 MPa) can reduce air consumption and footprint. For a 20 mm stroke, the SC250X20S is a standard-stroke model (max standard stroke for bore 250 is 1500 mm).
When replacing an existing cylinder, match five points: 250 mm bore, 20 mm stroke, PT1" ports, the built-in magnet (-S), and the basic (no bracket) mounting style. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC250X20S FAQ
At 0.7 MPa supply pressure, the push force on the extension stroke is 34361 N. The pull force on retraction is 23562 N, due to the 50 mm rod reducing the effective piston area.
Yes. The -S suffix in the model code indicates a built-in magnet. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect piston position without additional brackets.
