About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X170S
The SC200X170S is a large-bore, double-acting tie-rod cylinder delivering substantial push force of 15708 N at 0.5 MPa and up to 28274 N at 0.9 MPa operating pressure. With a 200 mm bore, 40 mm piston rod, and a 170 mm stroke, it is built for heavy-duty linear actuation where high force is the primary requirement.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for non-contact position sensing. The adjustable pneumatic cushion (33 mm length) decelerates the piston at end-of-stroke to reduce impact energy, while the PT3/4 port thread and standard TPU seals suit a wide range of industrial compressed-air systems.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X170S Is Used
Heavy Press & Clamping
Generates up to 28274 N of force at 0.9 MPa for powerful pressing, stamping, and clamping operations in metal forming and assembly fixtures.
Material Handling & Lifting
Provides the high thrust capacity needed for lifting, tilting, and transferring heavy pallets or components in automated logistics and warehousing systems.
Industrial Automation Gate
Drives heavy safety gates or diverters on large conveyor lines. The built-in magnet enables end-of-stroke confirmation via barrel-mounted sensors.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X170S the Right Cylinder?
Select the SC200 bore when your application requires push force in the 15708 N (0.5 MPa) to 28274 N (0.9 MPa) range. For a step down in force, the SC160 bore provides 10053 N at 0.5 MPa; for a step up, the SC250 bore delivers 24544 N at 0.5 MPa. This 170 mm stroke is within the standard range for the 200 mm bore, which supports strokes up to 1500 mm.
For a direct replacement, match five key attributes: 200 mm bore, 170 mm stroke, PT port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting configuration. If side loads are present, use an external guide system to protect the 40 mm rod and rod bearing from bending stress.
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 SC200X170S FAQ
At the standard operating pressure of 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, the push force reaches 28274 N. The theoretical maximum force at 1.0 MPa is 3204 kgf.
No. The SC200X170S is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston will drift. For load holding without pressure, you must add a pilot-operated check valve or an external mechanical rod brake.
