About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X80
The SC160X80 is a heavy-duty double-acting tie-rod cylinder delivering a substantial 10053 N of push force at just 0.5 MPa (18095 N at the 0.9 MPa maximum operating pressure). With an 80 mm stroke and a robust 40 mm diameter piston rod, this cylinder is built for short, high-force clamping, pressing, and lifting tasks in industrial machinery.
This model features a 239 mm body length, PT3/4 ports, and an adjustable air cushion with a 29 mm cushion length to decelerate the piston smoothly. As a genuine AirTAC SC series cylinder, it is a non-ISO tie-rod design that is shorter than an equivalent ISO 15552 cylinder, making it ideal where space is limited but force requirements are high.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X80 Is Used
Heavy-Duty Clamping
Generates over 10 kN of force at 0.5 MPa for secure workpiece clamping in machining centres and welding fixtures.
Industrial Pressing
Short 80 mm stroke with high force output suits bearing insertion, riveting, and small forming operations.
Scissor Lift Actuation
Powers the lifting mechanism in heavy-duty scissor lift tables and material handling platforms.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X80 the Right Cylinder?
Choose the SC160X80 when your application requires a force class around 10000 N at standard plant pressure. If your load is lighter, stepping down to the SC125 bore (6136 N push at 0.5 MPa) can reduce air consumption and physical size. For higher force, the SC200 bore (15708 N at 0.5 MPa) is the next step up.
For replacement, match five points: 160 mm bore, 80 mm stroke, PT3/4 port thread, basic mounting (no bracket), and no magnet. This cylinder does not hold position if air pressure is lost; use a pilot-operated check valve or external rod lock for load-holding applications.
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 SC160X80 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, push force reaches 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is shorter than an ISO 15552 profile cylinder, so dimensions are not interchangeable. Only replace with another AirTAC SC160 tie-rod cylinder of the same stroke, port, and mounting configuration.
