About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-100S
The AirTAC SAIJ160X325-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers substantial thrust, providing 18095N of push force at 0.9 MPa, making it suitable for heavy-duty operations. The integrated magnet supports position sensing via AirTAC CMSE reed and DMSE electronic switches.
This specific SKU features a 325 mm nominal stroke that can be dialed back by up to 100 mm, yielding a usable travel window of 225-325 mm. It incorporates a SUS304 stainless steel rod for superior corrosion resistance and is configured with PT tapered ports. Because the stroke exceeds 300 mm, an external guide is recommended to manage side loading and protect the rod seals.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-100S Is Used
Heavy Machinery Setup
Dial in the exact retract distance during heavy equipment commissioning using the 225-325 mm travel window, avoiding the need to physically swap out large actuators.
Product Line Changeover
Quickly adapt a manufacturing line to new part dimensions by turning the rear stopper, leveraging the 100 mm adjustment range to accommodate varied sizes.
Large Press Positioning
Utilize the 18095N push force at 0.9 MPa for large pressing operations while relying on the SUS304 rod for durability in harsh industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-100S the Right Cylinder?
Select this 160 mm bore cylinder when an application demands high force combined with variable end-position tuning; at 0.5 MPa it still generates 10053N of push force. If your setup requires less thrust, stepping down to a 125 mm bore yields 6136N at 0.5 MPa. The adjustable stroke is ideal for product changeovers, allowing you to fine-tune the retract position without swapping cylinders or adding external stops. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder. This model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR configurations.
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 SAIJ160BX325-100S FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053N of push force and 9425N of pull force. At 0.9 MPa, the push force increases to 18095N.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke by up to 100 mm. This creates a usable travel window of 225-325 mm from the 325 mm nominal stroke, enabling fine-tuning at commissioning without external stops.
