About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X365S
The AirTAC SC125X365S is a double-acting single-rod pneumatic cylinder delivering 6136 N of push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). With a 365 mm stroke and a 32 mm diameter piston rod, this model suits medium-to-heavy linear actuation tasks where a longer travel is required.
This variant includes the -S suffix for a built-in magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for contactless position sensing. The body length A is 203 mm, the adjustable air cushion is 28 mm, and the port is PT1/2, making it a genuine AirTAC cylinder ready for industrial automation.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X365S Is Used
Pallet & Case Handling
The 11045 N push at 0.9 MPa moves heavy pallets or cases on roller conveyors. The 365 mm stroke transfers loads between conveyor lanes, and the built-in magnet provides end-of-stroke confirmation via barrel-mounted sensors.
Heavy-Duty Clamping
Delivers 6136 N of clamping force at standard 0.5 MPa shop air for welding fixtures or CNC machining. The adjustable cushion decelerates the 32 mm rod smoothly at the end of the 365 mm travel, protecting the tooling.
Baler & Compactor Ejection
The SC125X365S provides the long, forceful push needed to eject compacted material from a baler chamber. The -S magnet lets PLCs verify full extension and retraction without physical contact, improving cycle reliability.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X365S the Right Cylinder?
Choose the SC125 bore when your application needs between roughly 5700 N and 11000 N of force; the next step down is the SC100 (3927 N at 0.5 MPa), and the step up is the SC160 (10053 N at 0.5 MPa). This 365 mm stroke is within the 1500 mm maximum standard stroke for the 125 mm bore. For strokes over 300 mm, always check for side loads—an unsupported 32 mm rod extending 365 mm can bend under lateral force. Use an external linear guide or a guided cylinder if side load is present.
To replace an existing cylinder, match five points exactly: 125 mm bore, 365 mm stroke, PT1/2 port thread, the built-in magnet (-S), and the basic (no bracket) mounting style. The SC is a tie-rod cylinder and is shorter than an ISO 15552 profile, so it is not a drop-in ISO replacement.
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 SC125X365S 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.
No. The AirTAC SC series is a tie-rod cylinder and its body length A (203 mm for the 125 bore) is shorter than an equivalent ISO 15552 cylinder. It is not dimensionally interchangeable with ISO 15552 profiles. For big bores 125-250, it is classed as ISO 6430.
