About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-100
The AirTAC SAIJ160X650-100 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a robust 14074N pull force at 0.7 MPa. It features a rear stopper mechanism that allows you to fine-tune the effective travel anywhere within a 550 to 650 mm window, eliminating the need to swap physical cylinders during product changeovers. This 160 mm bore unit is equipped with a PT tapered port and a SUS420J2 stainless steel piston rod, providing superior wear resistance and reliable performance in demanding environments.
Unlike fixed-stroke alternatives, this adjustable model lets you dial in the exact retract end-position at commissioning without bolting on external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting, though position detection requires adding a magnet. It supports a speed range of 30-500 mm/s and utilizes adjustable air cushions at both ends to decelerate the massive 2050 kgf maximum load smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-100 Is Used
Heavy Press Tuning
Dial in the exact 550-650 mm retract position on large metal forming presses to accommodate varying material thicknesses without changing tooling.
Pallet Diverter Setup
Adjust the end-stop on heavy-load conveyor diverters during product format changeovers, ensuring precise routing without mechanical rebuilds.
Large Assembly Jigs
Fine-tune the clamping reach on oversized assembly jigs where the exact end-position varies slightly between custom product batches.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-100 the Right Cylinder?
Select this 160 mm bore cylinder when your machinery requires substantial thrust, such as 14074N pull at 0.7 MPa, alongside variable end-stop positioning. If your application only needs standard positioning without the fine-tuning rear screw, the fixed-stroke SAI series is a simpler choice. For operations requiring less force, stepping down to a 125 mm bore yields 8590N push at 0.7 MPa, while moving up to a 200 mm bore provides 21991N push. When replacing an ISO 15552 cylinder, match the 160 mm bore, 650 mm stroke, 100 mm adjustment, PT port, and mounting interface.
Because the stroke extends to 650 mm, the 40 mm diameter rod is highly susceptible to side-loading forces; an external guide rail is strongly recommended to prevent premature seal wear. Remember that the rear adjuster and air cushions act only as travel stops and deceleration devices—they do not hold the load without live air pressure. For fail-safe load holding, integrate an external pilot-operated check valve or select the BSAI clamp-lock series.

- ✓ 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 SAIJ160 Adjustable Cylinder SAIJ160AX650-100 FAQ
The rear adjuster acts as an external stopper, allowing you to shorten the effective stroke by up to 100 mm. This creates a usable travel window between 550 and 650 mm, which can be fine-tuned during commissioning without replacing the cylinder.
At 0.7 MPa, it provides 14074N of push force and 14074N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 18095N.
