About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X750
The AirTAC SC160X750 is a double-acting pneumatic cylinder delivering substantial force for heavy-duty linear actuation. With a 160 mm bore, it generates 10053 N of push force at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa, driven by a robust 40 mm diameter piston rod.
This model features a 750 mm stroke, well within the 1500 mm maximum standard stroke for this bore size. The cylinder body length A is 239 mm, giving a total extended length of approximately 989 mm. It includes a 29 mm adjustable air cushion to decelerate the piston smoothly at end-of-stroke, protecting the end caps and reducing noise in high-cycle applications.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X750 Is Used
Heavy Machinery Actuation
Provides the high force needed for lifting, tilting, or shifting heavy components on agricultural and construction equipment, operating reliably on standard shop air.
Palletising & Conveyor Stops
Delivers 18095 N of thrust at 0.9 MPa to stop or lift heavy pallets on conveyor lines, with an adjustable cushion to manage impact at the end of the 750 mm stroke.
Press & Clamping Fixtures
Ideal for pneumatic presses and heavy-duty clamping tools where a 40 mm rod and tie-rod construction provide the rigidity needed for sustained holding force during machining.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X750 the Right Cylinder?
Select the SC160 when your application requires push forces in the 10053 N (at 0.5 MPa) to 18095 N (at 0.9 MPa) class. If your load is lighter, stepping down to an SC125 bore reduces force to 6136 N at 0.5 MPa, potentially saving space and air consumption. For higher forces, the SC200 bore offers 15708 N at the same 0.5 MPa pressure.
For this 750 mm stroke, ensure the rod is protected from significant side loads. Long, unsupported strokes on a single-rod cylinder can create bending moments on the rod bearing. If side load is present, use an external linear guide or consider a guided cylinder configuration. When replacing an existing unit, match five points exactly: 160 mm bore, 750 mm stroke, PT3/4 port thread, basic mounting (no bracket), and the absence of a magnet.
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 SC160X750 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 increases to 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No. The SC160X750 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 stroke end; it is not a locking or holding brake. For load holding, add a pilot-operated check valve or an external mechanical rod lock.
