About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X170
The SC200X170 is a double-acting tie-rod cylinder from the AirTAC SC series, delivering a substantial 15708 N of push force at 0.5 MPa operating pressure. With a 200 mm bore and 170 mm stroke, this model features a 40 mm diameter piston rod, M36x2 rod thread, and PT3/4 port connections.
Its 33 mm adjustable air cushion decelerates the piston smoothly at stroke end, protecting end caps and reducing noise. The body length A is 244 mm, giving a total extended length of approximately 414 mm. This cylinder is built with standard TPU/NBR seals for a temperature range of -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X170 Is Used
Heavy Press Tool Actuation
Provides 15708 N of push force at 0.5 MPa for clamping, pressing, and forming tools in metal fabrication and stamping lines.
Pallet Lifting & Transfer
Handles heavy pallet lifting and transfer stations in automated warehouses, using the 200 mm bore's high force output for reliable vertical motion.
Large Valve Automation
Operates large quarter-turn or gate valves in water treatment and process plants, where the 33 mm cushion absorbs end-of-stroke shock.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X170 the Right Cylinder?
Choose the SC200X170 when your application needs the force class of a 200 mm bore—15708 N push at 0.5 MPa. If you require less force, the SC160 bore delivers 10053 N push at the same pressure, offering a more compact alternative. For higher force demands, the SC250 bore provides 24544 N push at 0.5 MPa.
For replacement, match five key points: 200 mm bore, 170 mm stroke, PT3/4 port thread, basic mounting (no bracket), and no magnet. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC200 or equivalent tie-rod design. At 170 mm stroke, the rod is well-supported within standard limits, but always avoid side loads without an external guide.
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 SC200X170 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.
No. The SC200X170 is a double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centered. For load holding without live pressure, you must add a pilot-operated check valve or an external rod brake.
