About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X470S
The SC125X470S is a double-acting pneumatic cylinder delivering 6136 N push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). Its 32 mm diameter piston rod and 28 mm adjustable air cushion are sized for heavy mid-stroke industrial tasks, and the 470 mm stroke suits clamping, pressing, and material-transfer operations where a compact ISO 6430-class tie-rod body is preferred.
This model includes the -S built-in magnet, so CMSG/DMSG/EMSG reed or solid-state sensors clip directly onto the barrel for end-of-stroke detection without external brackets. The standard PT1/2 port and TPU seals cover -20 to +70 °C, and the total extended length is approximately 673 mm (body length A 203 mm + 470 mm stroke).

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X470S Is Used
Heavy Conveyor Divert
Pushes 6136 N at 0.5 MPa to divert pallets or heavy totes on roller conveyors; the magnet allows sensor confirmation at each end of the 470 mm travel.
Press-Fit Assembly
Generates up to 11045 N at 0.9 MPa for bearing or bushing insertion; the adjustable cushion protects tooling at the end of the 470 mm stroke.
Baler Compaction Gate
Operates a compaction gate on a recycling baler; the 28 mm cushion absorbs impact, and the built-in magnet confirms gate-open and gate-closed positions.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X470S the Right Cylinder?
For a step down in force, the SC100 bore provides 3927 N at 0.5 MPa; for more force, the SC160 bore delivers 10053 N at the same pressure. At 470 mm stroke, the 32 mm rod is robust, but any significant side load still requires an external linear guide or a guided-cylinder solution to protect the rod bearing. When replacing an existing unit, match five points: 125 mm bore, 470 mm stroke, PT1/2 port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration.
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 SC125X470S FAQ
At 0.5 MPa, push force is 6136 N and pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, push force reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
Yes. The -S suffix means a magnet is built into the piston, so AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors clamp directly onto the tie-rod barrel without any additional mounting hardware.
