About the Airtac SE125 Standard Cylinder SE125X80SCB
The AirTAC SE125X80SCB is a double-acting single-rod profile cylinder built to the ISO 15552 / VDMA 24562 standard. It features a robust 125 mm bore and an 80 mm stroke, delivering a substantial 6136 N push force at 0.5 MPa and up to 8590 N at 0.7 MPa. The square extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This specific configuration includes a CB double clevis mounting accessory for pivoting articulation and a built-in -S magnet compatible with AirTAC CMSE reed and DMSE electronic sensors. The field-adjustable pneumatic cushioning at both ends allows technicians to fine-tune end-of-stroke deceleration, softening the impact of heavy 1252 kgf maximum loads traveling within the 30-500 mm/s speed range.

Where the Airtac SE125 Standard Cylinder SE125X80SCB Is Used
Heavy-Duty Stamping Press
Provides the 6136 N push force required to drive stamping dies and form thick metal components in automated fabrication lines.
Pallet Dispenser Mechanism
Uses the CB double clevis mount to articulate smoothly while lifting heavy empty pallets within a high-speed end-of-line packaging system.
Injection Mold Ejection
Leverages the -S magnet with DMSE sensors to confirm mold ejection position, handling substantial stripping forces up to 1252 kgf.
Is the Airtac SE125 Standard Cylinder SE125X80SCB the Right Cylinder?
Selecting this 125 mm bore makes sense when your mechanism requires pushing or pressing forces around 6136 N at 0.5 MPa. If your load requirements are lighter, stepping down to the 100 mm bore yields a 3927 N push force, saving air volume and physical footprint. Conversely, if you need to pull a heavy load, this bore provides a 5734 N retract force. Remember that a standard SE cylinder relies on live air pressure to hold a load; if your pivoting CB mount setup must resist drift during an air loss or valve centering event, you must integrate an external rod lock or pilot-operated check valve rather than relying on the cushions. To retrofit an existing machine, match the 125 mm bore, 80 mm stroke, PT1/2 port, CB mount, and -S magnet to ensure a drop-in ISO 15552 dimensional replacement.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE 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 (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SE125 Standard Cylinder SE125X80SCB FAQ
This 125 mm bore cylinder features a PT1/2 port and a 32 mm rod. It generates a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push force reaches 8590 N, with a maximum push capacity of 1252 kgf at 1.0 MPa.
