About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X320
The AirTAC SC160X320 is a heavy-duty double-acting pneumatic cylinder delivering 10053 N of push force at 0.5 MPa and up to 18095 N at the maximum 0.9 MPa operating pressure. Its 40 mm diameter piston rod and 320 mm stroke make it a workhorse for demanding industrial linear motion tasks.
This tie-rod cylinder features an adjustable air cushion (29 mm length) at both ends to decelerate high-inertia loads smoothly. The body length A is 239 mm, giving a total extended length of approximately 559 mm. Ports are PT3/4 with an M36x2 rod thread, and the standard TPU seals suit operating temperatures from -20 to +70 C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X320 Is Used
Sawmill & Timber Processing
Powers log clamps, carriage drives, and veneer press rams where high force and resistance to dirty, wet conditions are essential.
Heavy Agricultural Machinery
Operates large gates, chutes, and implement positioning systems on harvesters and spreaders, providing reliable 10 kN+ push force.
Scrap & Recycling Balers
Drives the main compression plate in two-ram balers for cardboard, plastics, and non-ferrous metals, handling continuous high-cycle operation.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X320 the Right Cylinder?
Select the SC160X320 when your application needs around 10000 N of force at standard plant air pressure. If you can accept a smaller footprint, stepping down to the SC125 bore reduces push force to 6136 N at 0.5 MPa. For even higher force requirements, the SC200 bore provides 15708 N at the same pressure.
For this 320 mm stroke, ensure the load is guided and side forces are minimized to protect the rod bearing. When replacing an existing cylinder, match five points exactly: 160 mm bore, 320 mm stroke, PT3/4 port thread, basic (no bracket) mounting, and the absence of a magnet. This model does not include a built-in magnet for sensors.
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 SC160X320 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 at 1.0 MPa is 2050 kgf.
No. The SC160X320 is a standard double-acting cylinder and will drift or drop if air pressure is lost or the directional valve is centered. For load holding, you must add an external rod brake, a pilot-operated check valve, or a mechanical lock.
