About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X160S
The SC250X160S is a double-acting tie-rod cylinder delivering 24544 N of push force at 0.5 MPa (44178 N at the 0.9 MPa maximum operating pressure). Its 50 mm diameter piston rod and 40 mm adjustable air cushion handle high-inertia loads, while the 160 mm stroke suits medium-travel clamping and pressing operations.
This model carries the -S suffix, equipping the cylinder with a built-in magnet. CMSG, DMSG, or EMSG reed and solid-state sensors can be clamped directly onto the barrel for reliable, non-contact end-of-stroke or mid-position sensing without external brackets.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X160S Is Used
Heavy-Duty Pressing
44178 N of thrust at 0.9 MPa drives large-area pressing, laminating, and forming tools in wood, rubber, and composite processing.
Structural Testing Rigs
The 50 mm rod and 40 mm cushion absorb shock in load-frame actuators where high force and repeatable deceleration are critical.
Pallet & Container Lifting
24544 N at 0.5 MPa lifts heavy pallets or container lids. The built-in magnet enables sensor feedback for lift/lower confirmation.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X160S the Right Cylinder?
The SC250 bore generates 24544 N at 0.5 MPa. For a lighter force class, step down to the SC200 bore (15708 N at 0.5 MPa). For even higher force, confirm the next frame size from the datasheet. At 160 mm stroke the rod is well supported, but if the application introduces side load, pair the cylinder with an external guide or a guided-cylinder unit to protect the rod bearing.
To replace an existing cylinder, match five points: 250 mm bore, 160 mm stroke, PT port thread, basic mounting (no bracket), and the -S magnet for sensor compatibility. The SC is a tie-rod design 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 SC250X160S FAQ
At 0.7 MPa the SC250 bore produces 34361 N of push force. The pull force at the same pressure is 23562 N, accounting for the 50 mm rod area.
Yes. The -S suffix means a magnet is built into the piston. You can clamp AirTAC CMSG (reed), DMSG, or EMSG (solid-state) sensors directly onto the barrel to detect piston position.
