About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-40S
The AirTAC SAIJ160X325-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the retract end position without swapping out the unit. With a 325 mm nominal stroke and a 40 mm adjustment range, it provides a usable travel window of 285-325 mm for precise commissioning. This bore size delivers substantial thrust, generating 14074 N of push force at 0.7 MPa.
This specific SKU features a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the standard PT tapered port threads match the G3/8 port size. The rear adjuster acts purely as a mechanical stop for deceleration and positioning; it does not lock the load without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-40S Is Used
Product Changeover
Dial in the 285-325 mm travel window during format changeovers on packaging lines to accommodate different carton depths without changing hardware.
Heavy Press Fit
Leverage the 14074 N push force at 0.7 MPa to seat large bearings, utilizing the rear stopper to precisely limit insertion depth and prevent over-travel.
Material Forming
Set exact end-stops for heavy-duty bending or forming tasks, using the 40 mm adjustment screw to fine-tune the final rest position during machine setup.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-40S the Right Cylinder?
Choose this 160 mm bore when an 80 mm cylinder (providing 3518 N push force at 0.7 MPa) lacks the power to move your payload, but you want to avoid the massive 15708 N output of a 200 mm bore. The adjustable 285-325 mm window is ideal for production lines that undergo frequent product-size changeovers, eliminating the need to physically swap cylinders or bolt on external stops like you would with a fixed-stroke SAI model.
Because the 325 mm stroke is relatively long, an external guide should be used to support the load and prevent excessive side-loading on the SUS304 rod. If your application requires the load to be held in place without constant air pressure, this cylinder will not suffice; you should look at the SAIL air-released lock or BSAI clamp-lock series instead. For an exact ISO 15552 replacement match, verify the 160 mm bore, 325 mm stroke, 40 mm adjustment, PT G3/8 ports, and the -S magnet requirement.
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 SAIJ160BX325-40S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 13074 N of pull force. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the 325 mm nominal stroke by up to 40 mm, creating a usable travel window of 285-325 mm. This stopper only sets the end position and deceleration; it does not lock the load without live air pressure.
