About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-10
The AirTAC SAIJ160X325-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 315-325 mm, allowing you to dial back the 325 mm nominal stroke by up to 10 mm during commissioning. Belonging to a high-force class, it delivers 18095N of push force at 0.9 MPa, making it suitable for heavy-duty positioning tasks.
This model is configured with a SUS304 stainless steel rod (code B) for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides, ready to accept AirTAC CMSE reed or DMSE electronic sensors if position feedback is added later. It supports a speed range of 30-500 mm/s and includes variable air cushions at both ends to manage deceleration.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-10 Is Used
Heavy-Duty Press Fine-Tuning
Dial in the exact 315-325 mm retract position during machine setup to accommodate material thickness variations without external stopper blocks.
Automated Assembly Line
Provides 18095N of push force at 0.9 MPa for pressing heavy components, with the 10 mm adjustment allowing quick changeover between product sizes.
Large Pallet Positioning
Halts large pallets precisely at a variable end-stop, using the rear adjuster to trim the stroke for different pallet dimensions on the same line.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-10 the Right Cylinder?
Choose this adjustable-stroke cylinder when your application requires exact end-position tuning without swapping out components or adding external stops. If you need less force, stepping down to a 125 mm bore yields 11045N of push at 0.9 MPa, while a 200 mm bore provides 28274N for heavier loads. Because the 325 mm stroke exceeds 300 mm, an external guide is recommended to prevent excessive side-loading on the rod.
The rear adjuster acts purely as a travel stop to fine-tune the retract position, so it will not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL pneumatic lock or BSAI clamp-lock series. When replacing an ISO 15552 cylinder, match the 160 mm bore, 325 mm stroke, 10 mm adjustment, PT G3/4 port, and standard mounting options (Basic, FA, LB, TC, FTC, TCM1, TCM2).

- ✓ 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 SAIJ160BX325-10 FAQ
The rear adjusting screw acts as an external stopper that lets you shorten the effective stroke by up to 10 mm, providing a usable travel window of 315-325 mm. It sets the end position but does not lock the load without live air pressure.
This 160 mm bore cylinder generates 10053N of push force at 0.5 MPa and 18095N at 0.9 MPa. The pull force is 9425N at 0.5 MPa and 16965N at 0.9 MPa.
