About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X400SH
The SC160X400SH is a large-bore double-acting tie-rod cylinder delivering 10053 N of push force at 0.5 MPa, scaling to 18095 N at the 0.9 MPa maximum operating pressure. Its 40 mm diameter piston rod and 29 mm adjustable air cushion provide robust deceleration for heavy, high-inertia loads through a 400 mm stroke.
This variant is factory-built with Viton (FKM) seals, shifting the operating temperature range to 0–150 °C for hot environments where standard TPU seals would degrade. The body length A is 239 mm, giving a total extended length of approximately 639 mm, and the PT3/4 port supplies ample flow for high-speed cycling of large pneumatic systems.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X400SH Is Used
Kiln & Oven Door Actuation
The Viton seals withstand 150°C ambient heat, making this cylinder suitable for opening and closing industrial oven or kiln doors where standard seals would fail.
Heavy Press & Compaction
With 18095 N of force at 0.9 MPa, the SC160X400SH powers waste compactors, baling presses, and agricultural packers requiring a long 400 mm compaction stroke.
Hot Fluid Valve Control
Ideal for modulating large valves on steam or hot process fluid lines, where the cylinder body is exposed to radiant heat and the double-acting control ensures reliable open/close cycles.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X400SH the Right Cylinder?
Choose the SC160 when your application needs the 10053 N push force at 0.5 MPa. If you can step down in force, the SC125 bore provides 6136 N at the same pressure in a lighter package; for more force, the SC200 bore delivers 15708 N. This 400 mm stroke is well within the 1500 mm maximum standard stroke for the 160 bore.
At 400 mm stroke, ensure the rod is not subjected to significant side loading—the 40 mm rod can bend under off-axis forces. Use an external guide rail or a guided cylinder if the load is not perfectly aligned. For replacement, match five points: 160 mm bore, 400 mm stroke, PT3/4 port thread, basic mount (no bracket), and no magnet. The H suffix specifies Viton seals for high-temperature compatibility.
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 AIRTAC SC125-160 Standard Cylinder SC160X400SH FAQ
At 0.7 MPa operating pressure, the theoretical push force is 14074 N and the pull force on the retract stroke is 9425 N. At the maximum operating pressure of 0.9 MPa, push force reaches 18095 N.
No. The SC160X400SH is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. To hold a heavy load safely without live pressure, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
