About the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX105-10
The AirTAC SAIJ125X105-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering substantial thrust for heavy-duty operations. Outfitted with a SUS420J2 stainless steel rod (material code A), it provides excellent resistance to wear and corrosion in demanding environments. The extruded aluminum barrel features integrated sensor grooves on both sides for straightforward switch mounting.
With a nominal stroke of 105 mm and a 10 mm adjustment range, this SKU provides a usable travel window of 95 to 105 mm. This allows you to dial in the exact retract end-position during commissioning without adding external stops. The PT tapered port threads match the G1/2 bore specification, while the variable air cushions at both ends absorb kinetic energy at the stroke ends.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX105-10 Is Used
Heavy-Duty Press Fitment
Fine-tune the 95-105 mm stroke window during machine setup to achieve precise pressing depths on heavy assemblies without swapping out the entire actuator.
Product Line Changeover
Quickly adjust the retract end-stop by up to 10 mm to accommodate slight variations in product sizes on a high-force conveyor line.
Large Material Handling
Leverage the 6136 N push force and SUS420J2 stainless steel rod to move heavy pallets or structural components safely in rugged industrial settings.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX105-10 the Right Cylinder?
Select this 125 mm bore when your application requires high force, yielding 6136 N of push thrust and 5734 N of pull thrust at 0.5 MPa. If your fixture needs less force, stepping down to a 100 mm bore provides 3927 N of push force at the same pressure, whereas moving up to a 160 mm bore offers 10053 N for heavier loads. The 10 mm adjustable stroke is ideal for product changeovers that require slight position tuning rather than a completely new cylinder.
Because the 105 mm stroke is relatively short, side-loading is less pronounced than with longer strokes, but an external guide is still recommended for heavy offsets. The rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. This model uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552.
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 SAIJ125 Adjustable Cylinder SAIJ125AX105-10 FAQ
At an operating pressure of 0.5 MPa, this 125 mm bore cylinder generates 6136 N of push force and 5734 N of pull force. At 0.7 MPa, the push force increases to 8590 N.
The rear adjusting screw allows you to shorten the effective stroke by up to 10 mm from the 105 mm nominal length, creating a 95-105 mm travel window. This stopper fine-tunes the end position but does not lock the load without live air pressure.
