About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-100S
The AirTAC SAIJ160X900-100-S is a double-acting ISO 15552 profile cylinder featuring a 160mm bore and a 900mm stroke. It integrates a rear stopper mechanism that allows you to trim the effective travel back by up to 100mm, creating a precise 800-900mm usable adjustment window. This fine-tuning capability is executed entirely at commissioning without requiring external stops or cylinder swaps. Delivering 10053N of push force at 0.5MPa, it is built for heavy-duty tasks.
This SKU is configured with an SUS420J2 stainless steel rod (code A) for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes dual sensor grooves, and because this model includes the -S magnet, it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise end-of-stroke detection. Speeds range from 30-500mm/s, and it utilizes a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-100S Is Used
Heavy Press Fine-Tuning
Dial in the exact 800-900mm end position during machine commissioning to accommodate varying material thicknesses without adding external mechanical stops.
Product Size Changeover
Quickly adjust the retract end-stop on automated assembly lines when switching between different product lengths, reducing setup downtime significantly.
Long-Stroke Material Handling
Manage heavy push loads of 10053N in large-scale conveyor transitions, utilizing the SUS420J2 stainless rod to withstand harsh industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-100S the Right Cylinder?
Select this 160mm bore cylinder when an application requires substantial thrust, such as the 10053N push or 9425N pull force generated at 0.5MPa. If your process demands less force, stepping down to a 100mm bore yields 3927N of push force, while moving up to a 200mm bore provides 15708N. The adjustable stroke is highly beneficial for product changeovers on long-stroke equipment, allowing operators to dial in the exact end position without swapping components. For any stroke of 900mm, an external guide is strongly recommended to manage side-load stresses on the rod.
When matching ISO 15552 dimensions for a replacement, verify the 160mm bore, 900mm stroke, 100mm adjustment range, PT G3/4 port, and the -S magnet requirement. Remember that the rear adjuster acts only as a travel stop and the air cushions manage deceleration; neither holds the load without live air pressure. For true load-holding capabilities without continuous air supply, consider the AirTAC SAIL pneumatic lock or BSAI clamp-lock series instead.

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 SAIJ160AX900-100S FAQ
The rear adjuster screw acts as an external stopper that lets you shorten the 900mm nominal stroke by up to 100mm. This creates a usable travel window of 800-900mm, allowing you to fine-tune the retract end position at commissioning without replacing the cylinder.
At 0.5MPa operating pressure, it provides 10053N of push force and 9425N of pull force. The standard speed range for this 160mm bore is 30-500mm/s.
