About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X550STC
The SC160X550STC is a double-acting pneumatic cylinder delivering substantial force for heavy industrial automation. With a 160 mm bore and 550 mm stroke, it generates 10053 N of push force at 0.5 MPa (18095 N at the 0.9 MPa maximum operating pressure), making it suitable for pressing, clamping, and lifting large assemblies.
This model features a built-in magnet (S) for mounting CMSG/DMSG/EMSG sensors directly on the tie-rod barrel, and a centre trunnion mount (TC) with the TCM1 bracket for pivoting applications. The 40 mm diameter piston rod and 29 mm adjustable air cushion provide robust deceleration for high-inertia loads, while the PT1/2 port thread ensures standard pneumatic connections.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X550STC Is Used
Pallet Transfer Systems
The 550 mm stroke and trunnion mount allow this cylinder to pivot while pushing heavy pallets between conveyor lines, with the magnetic piston confirming end-of-travel via barrel-mounted sensors.
Heavy-Duty Clamping Fixtures
Generating over 18000 N of force at 0.9 MPa, the SC160X550STC securely clamps large weldments or castings during machining, with the adjustable cushion absorbing impact for consistent cycle times.
Automotive Component Pressing
Ideal for pressing bearings or bushings into housings on an assembly line, where the 40 mm rod resists buckling and the centre trunnion allows the cylinder to align with the press tooling.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X550STC the Right Cylinder?
Choose the SC160 when your application requires forces in the 10000 N class at standard shop air. If your load is lighter, stepping down to an SC125 bore reduces push force to 6136 N at 0.5 MPa, saving energy and space. For heavier demands, the SC200 bore offers 15708 N at the same pressure.
At a 550 mm stroke, the 40 mm rod is well-supported, but always avoid direct side loading on the rod end. For guided motion, pair this cylinder with an external linear guide or consider a dedicated guided cylinder. To replace an existing unit, match five points: 160 mm bore, 550 mm stroke, PT port thread, centre trunnion (TC) mounting accessory (F-SC160TC), and the built-in magnet (-S) for sensor compatibility.

- ✓ 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 SC160X550STC 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 SC160X550STC 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 cushions only decelerate the piston at the end of stroke. For load holding without live pressure, you must add an external rod lock or a pilot-operated check valve.
