About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X500H
The AirTAC SC160X500H is a double-acting tie-rod cylinder equipped with high-temperature Viton (FKM) seals, extending its operating range to 0–150 °C for demanding hot environments. With a 160 mm bore and 500 mm stroke, it generates a substantial 10053 N of push force at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa.
This model features a 40 mm diameter piston rod with M36x2 male threads and a 29 mm adjustable air cushion at each end to decelerate heavy loads. The body length A is 239 mm, making the total extended length approximately 739 mm. PT3/4 port threads supply the filtered air, and the cylinder is rated for a proof pressure of 1.5 MPa.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X500H Is Used
High-Temperature Press Actuation
Viton seals allow this cylinder to operate reliably in hot presses, autoclaves, and foundry equipment where ambient temperatures reach up to 150 °C, providing consistent 10 kN-class force.
Heavy-Duty Clamping & Forming
With 18095 N of thrust at 0.9 MPa, the SC160X500H powers large forming dies, injection mold clamps, and heavy material bending fixtures in industrial manufacturing.
Industrial Gate & Diverter Control
The 500 mm stroke and high force output are ideal for actuating large material diverters, hopper gates, and chute controls in mining, aggregate, and bulk handling systems.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X500H the Right Cylinder?
For applications requiring slightly less force, the SC125 bore delivers 6136 N push at 0.5 MPa, while stepping up to the SC200 bore provides 15708 N. This 500 mm stroke is well within the 1500 mm maximum standard stroke for the 160 bore. When mounting this cylinder, ensure the rod is not subjected to significant side loads; for long strokes or off-axis forces, use an external guide rail to protect the rod bearing and piston seals.
To replace an existing unit, match five key points: 160 mm bore, 500 mm stroke, PT port thread, basic (no bracket) mounting, and no magnet. The Viton seal variant (H) is specifically for high-temperature service; ensure the replacement also carries the H suffix if operating above 70 °C.
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 SC160X500H FAQ
At 0.5 MPa, the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No. The SC160X500H is a double-acting cylinder and will not hold its position if pressure is exhausted or the directional valve is centered. For load-holding safety, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
