About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X75H
The AirTAC SC160X75H is a robust double-acting tie-rod cylinder delivering a push force of 10053 N at 0.5 MPa, rising to 18095 N at the maximum operating pressure of 0.9 MPa. This model features a 75 mm stroke and is equipped with high-temperature Viton (FKM) seals, extending the operating temperature range to 0–150 °C, making it suitable for processes involving elevated ambient heat or aggressive media.
With a 40 mm diameter piston rod and a 29 mm adjustable air cushion, the SC160X75H decelerates end-of-stroke loads smoothly, protecting connected machinery. The body length A is 239 mm, and the PT3/4 port thread provides ample flow for rapid cycling in heavy-duty industrial tasks.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X75H Is Used
High-Temperature Clamping
Viton seals allow this cylinder to operate reliably in hot presses, autoclaves, and foundry equipment where ambient temperatures reach up to 150 °C, maintaining consistent clamping force.
Heavy-Duty Pressing
Generating over 18000 N of force at 0.9 MPa, the SC160X75H is ideal for short-stroke pressing, stamping, and riveting operations on metal or composite workpieces.
Material Gate Actuation
Use this 75 mm stroke cylinder to divert or stop heavy materials on conveyor lines, with the adjustable cushion absorbing impact for smooth, repeatable gate movement.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X75H the Right Cylinder?
Select the SC160X75H when the 125 mm bore's push force of 6136 N at 0.5 MPa is insufficient for the load. If your application requires even higher force capacity, step up to the 200 mm bore, which provides 15708 N at the same pressure. For strokes of 300 mm or longer, evaluate side-load conditions and consider an external guide or a guided cylinder to protect the 40 mm rod from bending stress.
To ensure a correct replacement, match five key points: 160 mm bore, 75 mm stroke, PT3/4 port thread, the basic (no bracket) mounting configuration, and the absence of a built-in magnet. This cylinder uses the standard PT port thread and does not include a magnetic piston.
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 SC160X75H FAQ
The theoretical push force at 0.5 MPa is 10053 N, and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 18095 N. The maximum theoretical force at 1.0 MPa is 2050 kgf.
No, the SC160X75H is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The adjustable air cushion only decelerates the piston at the end of stroke. For load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod lock.
