About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X20S
The SC200X20S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 200 mm bore with a short 20 mm stroke and a built-in magnet for barrel-mounted sensors. With a 40 mm diameter piston rod and PT3/4 ports, this cylinder generates a substantial push force of 15708 N at 0.5 MPa (28274 N at 0.9 MPa), making it suitable for heavy clamping, pressing, or ejection tasks where travel is minimal.
This model includes the -S suffix, equipping the cylinder with a magnet embedded in the piston. This allows CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly onto the tie-rod barrel for non-contact position sensing. The standard TPU seals provide an operating temperature range of -20 to +70 °C, and the adjustable air cushion at each end decelerates the high-inertia load smoothly over a 33 mm cushion length.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X20S Is Used
Heavy-Duty Clamping
Short 20 mm stroke with 15708 N push force at 0.5 MPa for secure workpiece clamping in machining fixtures.
Press-Fit Assembly
Delivers controlled, high-force insertion for bearings or bushings with sensor feedback via the built-in magnet.
Product Ejection
Rapid 20 mm ejection stroke on packaging or sorting lines, with CMSG/DMSG sensors confirming retract and extend positions.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X20S the Right Cylinder?
Choose the SC200X20S when you need maximum force in a very short stroke—its 15708 N push at 0.5 MPa far exceeds the SC160 (10053 N) and SC125 (6136 N) at the same pressure. If the application requires a longer stroke up to 1500 mm, the standard SC200 series supports it, but for this 20 mm stroke, ensure the short travel does not prevent the piston from reaching a fully cushioned deceleration zone. For side-loading conditions, even on a short stroke, guide the 40 mm rod externally or pair the cylinder with a guided unit to protect the rod bearing from bending moments.
To replace an existing cylinder, match five points: 200 mm bore, 20 mm stroke, PT3/4 port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration. 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 SC200X20S FAQ
At 0.5 MPa the push force is 15708 N and the pull force is 15080 N. At the maximum operating pressure of 0.9 MPa, push force reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
Yes. The -S suffix indicates a built-in magnet, so you can clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder's tie-rod barrel to detect piston position.
