About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X550S
The AirTAC SC160X550S is a double-acting single-rod tie-rod cylinder with a 160 mm bore and a 550 mm stroke. It generates a substantial push force of 10053 N at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa, driven by a 40 mm diameter piston rod.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the barrel for contactless position sensing. The adjustable pneumatic cushion at each end (29 mm length) decelerates the piston to soften end-of-stroke impact, protecting the cylinder and the machine structure.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X550S Is Used
Heavy Press Tool Actuation
Operates clamping or forming tools in large hydraulic-style presses, delivering up to 18095 N of push force at 0.9 MPa for consistent material deformation.
Palletizer Layer Pusher
Provides the high force needed to push a full layer of boxes onto a pallet, with the 550 mm stroke covering the full pallet depth in one smooth motion.
Log Sawmill Carriage Drive
Drives the carriage of a large log saw, using the 10053 N force at 0.5 MPa for steady feed rates. The built-in magnet provides end-of-travel confirmation in dusty environments.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X550S the Right Cylinder?
Choose the SC160 bore when your application requires a push force between roughly 10053 N (at 0.5 MPa) and 18095 N (at 0.9 MPa). If your force requirement is lower, stepping down to an SC125 bore reduces the push force to 6136 N at 0.5 MPa. For a 550 mm stroke, ensure the rod is protected from significant side loads; consider an external guide or a guided cylinder if the load is not purely axial, as a 40 mm rod extended over half a meter is vulnerable to bending stress.
To replace an existing cylinder, match five critical points: the 160 mm bore, 550 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the basic mounting style. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC or an equivalent tie-rod design.
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 SC160X550S 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.
Yes. The -S suffix in the model code indicates a built-in magnet around the piston. This allows you to clamp compatible AirTAC CMSG, DMSG, or EMSG sensors onto the cylinder barrel to detect piston position without any mechanical contact.
