About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X275
The SC160X275 is a heavy-duty double-acting tie-rod cylinder delivering 10053 N of push force at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa. With a 275 mm stroke and a robust 40 mm diameter piston rod, this cylinder is built for demanding industrial linear motion tasks where high force and a compact footprint are required.
This model features a 29 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 239 mm, making the total extended length approximately 514 mm. It uses PT3/4 ports and an M36x2 rod thread, conforming to the ISO 6430 class for large-bore tie-rod cylinders.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X275 Is Used
Heavy Press & Clamping
Generates over 18000 N of force at 0.9 MPa for powerful clamping, pressing, and riveting operations in metal fabrication and assembly cells.
Pallet Stop & Lift
Ideal for heavy pallet handling systems, providing the high force needed to lift, stop, or divert pallets on gravity or powered roller conveyors.
Large Valve Actuation
Provides the thrust and stroke necessary to operate large quarter-turn valves, dampers, or hopper gates in water treatment and bulk material handling.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X275 the Right Cylinder?
Select the SC160X275 when your application requires a force class around 10000 N at standard shop air. If you can accept a smaller envelope, stepping down to an SC125 bore reduces push force to 6136 N at 0.5 MPa. For higher force requirements, the SC200 bore provides 15708 N at the same pressure. Ensure a precise replacement by matching five key points: 160 mm bore, 275 mm stroke, PT3/4 port thread, basic mounting (no included brackets), and the absence of a built-in magnet.
For a 275 mm stroke, side-loading on the 40 mm rod must be managed carefully. Avoid direct lateral forces on the rod end; instead, couple the load through a rod-alignment coupler or integrate an external linear guide to absorb bending moments and prevent premature rod bearing and seal wear.
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 SC160X275 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 SC160X275 is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at the stroke end. For load holding, you must add an external rod lock or a pilot-operated check valve.
