About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1800
The AirTAC SC160X1800 is a double-acting tie-rod cylinder engineered for applications requiring an exceptionally long 1800 mm stroke from a 160 mm bore. This non-standard stroke length exceeds the standard 1500 mm maximum, making it a made-to-order unit for specialized linear motion tasks. At 0.5 MPa air pressure, it generates a substantial push force of 10053 N and a pull force of 9425 N, driven by a robust 40 mm diameter piston rod.
With a body length (A) of 239 mm, the total extended length is significant, requiring careful attention to mounting and support. The cylinder features a 29 mm adjustable air cushion to decelerate the high inertial loads typical at the end of such a long stroke. It uses PT3/4 ports and an M36x2 rod thread, and is built with standard TPU seals for a -20 to +70 °C operating range.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1800 Is Used
Long-Reach Material Pusher
Ideal for a gantry-mounted pusher in a warehouse distribution system, using its 1800 mm stroke to divert large, heavy packages across a wide conveyor network with 10053 N of force.
Forestry & Sawmill Log Deck
Powers a log kicker or stop gate on a sawmill infeed deck, where the long stroke and high force are needed to manage heavy timber, operating reliably in dirty conditions.
Large Panel Press Unloader
Extends fully into a large-format press to push out finished engineered wood panels or composite sheets, with the adjustable cushion softening the impact of the heavy moving platen.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1800 the Right Cylinder?
Select the SC160X1800 when your application demands a very long reach with a force output around 10053 N at 0.5 MPa. If a higher force is required, stepping up to the SC200 bore provides 15708 N of push force at the same pressure. For applications needing less force in a more compact package, the SC125 bore delivers 6136 N.
For any stroke of this length, side loading on the 40 mm rod is a critical design factor. An unsupported 1800 mm stroke will subject the rod bearing to high bending moments. It is essential to use an external guide system or a self-guided tooling plate to prevent rod deflection and premature seal wear. When replacing this cylinder, ensure the new unit matches the 160 mm bore, 1800 mm stroke, PT3/4 port thread, basic mounting style, 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 SC160X1800 FAQ
At the standard 0.5 MPa operating pressure, 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.
A stroke of 1800 mm on a 40 mm rod requires external guidance. Never rely on the cylinder's rod bearing alone to support a side load. You must mount the tooling on a separate set of linear guide rails and bearings, or use a self-guided unit, and connect the cylinder rod with a floating coupling to prevent binding and seal damage.
