About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-30S
The AirTAC SAIJ160X350-30-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 320 to 350 mm, allowing you to dial back the end position by up to 30 mm during commissioning without swapping the hardware. Belonging to a heavy-duty bore class, it yields a push force of 14074 N at 0.7 MPa and a pull force of 9425 N.
This specific SKU incorporates a SUS304 stainless steel rod for superior corrosion resistance and includes a built-in magnet for position sensing via CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to fine-tune travel, not as a load-holding lock, and the extruded aluminum barrel maintains standard ISO 15552 mounting dimensions.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-30S Is Used
Product Changeover
Dial in the 320-350 mm travel window rapidly when switching the production line to accommodate a different sized workpiece without changing out the entire actuator.
Heavy Press Fit
Leverage the 14074 N push force at 0.7 MPa to seat large mechanical components, using the rear stopper to prevent over-travel during the final assembly phase.
Machine Setup
Fine-tune the retract end position during initial commissioning to perfectly align heavy tooling mounts, avoiding the need for custom external mechanical shims.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-30S the Right Cylinder?
Select this 160 mm bore unit when your application requires 14074 N of push force at 0.7 MPa and on-the-fly end-position tweaking. If your setup needs less force, stepping down to a 125 mm bore yields 8590 N at the same pressure. Because the 350 mm stroke is substantial and paired with a 40 mm diameter rod, long unsupported travel demands an external guide to prevent side-loading damage.
The PT tapered port threads match the G3/8 air supply requirement for this bore size. Remember that the rear stopper only trims the retract end, so if your process requires true fail-safe load holding without live air pressure, you must integrate an external rod lock or choose a related SAIL or BSAI clamp-lock cylinder instead of relying on the standard air cushions.
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 SAIJ160BX350-30S FAQ
The rear adjuster screw allows you to shorten the nominal 350 mm stroke by up to 30 mm, creating a usable travel window of 320 to 350 mm. It functions strictly as a mechanical stop to set the end position and does not lock the load.
At an operating pressure of 0.7 MPa, the SAIJ160X350-30-S generates a push force of 14074 N and a pull force of 9425 N. The maximum push force reaches 18095 N at 0.9 MPa.
