About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X265S
The SC125X265S delivers 6136 N of push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure), placing it firmly in the heavy-duty automation class. With a 265 mm stroke and a 32 mm diameter piston rod, this double-acting tie-rod cylinder is suited to pressing, clamping, and material-handling tasks that demand substantial force in a compact footprint.
The built-in magnet (denoted by the -S suffix) allows CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly onto the barrel for reliable end-of-stroke or mid-stroke position sensing. Its adjustable air cushion (28 mm length) decelerates the piston smoothly, reducing end-cap impact. Operating on filtered air from 0.15 to 1.0 MPa, the standard TPU seals provide a temperature range of -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X265S Is Used
Palletising & Material Handling
The 6136 N push force at 0.5 MPa and 265 mm stroke reliably lift and transfer heavy totes or pallets on end-of-arm tooling and lift stations.
Heavy Pressing & Assembly
Delivers up to 11045 N at 0.9 MPa for bearing insertion, riveting, or forming operations, with sensor feedback for quality interlocking.
Gate & Diverter Actuation
The robust 32 mm rod and tie-rod construction withstand the repetitive shock of diverting heavy packages on high-speed conveyor lines.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X265S the Right Cylinder?
For applications requiring slightly less force, the 100 mm bore SC100 series provides 3927 N at 0.5 MPa, while stepping up to the 160 mm bore yields 10053 N. This 125 mm bore is an ISO 6430 class cylinder, offering a robust tie-rod construction that is shorter than an equivalent ISO 15552 profile cylinder.
When replacing this unit, match five key points: 125 mm bore, 265 mm stroke, PT port thread, the basic mounting configuration, and the built-in magnet for sensor compatibility. For strokes over 300 mm, always assess side-load conditions and consider an external guide or guided cylinder to protect the rod bearing from bending moments, though at 265 mm this model remains within typical unsupported stroke limits for its 32 mm rod.
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 SC125X265S FAQ
At 0.5 MPa, the push force is 6136 N and the 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 indicates a built-in magnet in the piston, so AirTAC CMSG, DMSG, or EMSG sensors clamp directly onto the barrel without additional brackets. This is a genuine AirTAC factory option.
