About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX400-10
The AirTAC SAIJ160X400-10 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster, allowing you to trim the effective stroke within a 390 to 400 mm window. Delivering a substantial 14074 N of push force at 0.7 MPa, this bore 160 unit handles heavy-duty positioning with ease. The extruded aluminum barrel features dual sensor grooves, though this specific configuration omits the magnet.
Built for demanding environments, this variant utilizes a SUS304 stainless steel rod for superior corrosion resistance and ships with PT tapered port threads. The rear stopper enables fine end-position tuning at commissioning without adding external stops, though it acts strictly as a travel limiter and not a load-holding lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX400-10 Is Used
Heavy Press Tuning
Dial in the exact 390 to 400 mm end-of-stroke position during machine commissioning to accommodate varying material thicknesses without external stopper blocks.
Product Changeover
Quickly adjust the rear stopper on a packaging line to handle different pallet or product sizes, reducing downtime between production runs.
Robotic Material Handling
Leverage the 14074 N push force and SUS304 rod to move heavy metal components, fine-tuning the retraction point to prevent collision with upstream tooling.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX400-10 the Right Cylinder?
Select this adjustable-stroke model when an application requires exact end-position tuning during setup or product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If your thrust requirements are lower, stepping down to a bore 125 cylinder yields 8590 N of push force at 0.7 MPa. Because the 400 mm stroke creates a long lever arm, an external guide is recommended to manage side loads and protect the 40 mm rod.
To match this cylinder for an ISO 15552 replacement, specify: 160 mm bore, 400 mm stroke, 10 mm adjustment, PT port thread, SUS304 (B) rod material, no magnet, and a mounting choice from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this series. For applications requiring the load to be held without live air pressure, a plain SAIJ is insufficient; consider an external rod lock or the AirTAC SAIL locking cylinder instead.
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 SAIJ160 Adjustable Cylinder SAIJ160BX400-10 FAQ
At 0.7 MPa, this bore 160 cylinder provides 14074 N of push force and 9425 N of pull force. At maximum 1.0 MPa pressure, it achieves up to 2050 kgf. The operational speed range for this size is 30 to 500 mm/s.
The rear adjuster acts as a mechanical stop that allows you to shorten the 400 mm nominal stroke by up to 10 mm, providing a usable travel window of 390 to 400 mm. It only sets the end position and does not lock or hold the load without continuous air pressure.
