About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-75
The AirTAC SAIJ160X900-75 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, delivering 14074N of push force at 0.7 MPa. It features a rear stroke adjuster that creates an 825-900mm usable travel window, enabling precise end-position tuning during commissioning without adding external stops. This model incorporates a SUS304 stainless steel piston rod for superior corrosion resistance and uses PT tapered port threads.
The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Because the 900mm stroke is substantial, the 40mm diameter rod and M36x2 thread provide a robust interface, though an external guide is recommended for unsupported loads. The rear adjuster acts strictly as a travel stop and deceleration setter, not a lock, so live air is required to maintain position.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-75 Is Used
Heavy Machinery Setup
Dial in the exact 825-900mm end position during large equipment assembly without machining custom stopper blocks.
Product Size Changeover
Quickly trim the retract stroke by up to 75mm on packaging lines to accommodate varying pallet heights.
Actuator Commissioning
Fine-tune the travel end during machine startup to absorb mechanical tolerances and prevent hard crashes.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-75 the Right Cylinder?
Selecting this 160mm bore cylinder makes sense when your application requires the 10053N pull force at 0.5 MPa and a highly variable end-stop. If you need less force, stepping down to a 100mm bore yields 3927N push at 0.5 MPa. Choose this adjustable-stroke SAIJ over a fixed SAI when you anticipate product changeovers that demand on-the-fly stroke trimming up to 75mm. For mounting, this series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 attachments, omitting FB, CA, CB, and CR.
If your process requires holding the load without continuous air pressure, the SAIJ adjuster will not suffice; you should specify an SAIL air-released lock, a BSAI clamp-lock, or an external rod lock. Given the 900mm stroke, ensure the mounting configuration accounts for side loads by utilizing a guide rail. This configuration uses PT ports and lacks a standard magnet, so position sensing requires external methods or a custom specification.
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 SAIJ160BX900-75 FAQ
At 0.7 MPa, this 160mm bore cylinder provides a push force of 14074N and a pull force of 13274N. At 0.5 MPa, the push force is 10053N.
The rear adjuster allows you to shorten the 900mm nominal stroke by up to 75mm, providing an adjustable travel window of 825-900mm. The adjuster is a mechanical stop and does not lock the load without live air pressure.
