About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX115-100S
It features a SUS304 stainless steel rod and a PT tapered port. Because the adjustment code is 100 mm on a 115 mm nominal stroke, you can dial back the effective travel anywhere within a 15 to 115 mm window. This extreme adjustability allows you to fine-tune end positions at commissioning without swapping out the physical cylinder.
The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) supports AirTAC CMSE reed and DMSE electronic solid-state switches. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Remember that the rear adjuster acts purely as a travel stop for deceleration, not as a lock, so it will not hold the load without live air pressure.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX115-100S Is Used
Variable End-Stop Tuning
Dial in the exact retraction point within the 15-115 mm window during machine setup, providing precise mechanical tuning without needing external stopper blocks.
Product Size Changeover
Rapidly adjust the cylinder travel on automated lines when switching between different product sizes, leveraging the 100 mm adjustment range to handle varied formats.
Stainless Rod Actuation
Utilize the SUS304 stainless steel rod in light-washdown or corrosive-adjacent manufacturing environments where carbon steel rods might degrade over time.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX115-100S the Right Cylinder?
An adjustable stroke is highly beneficial here: the 100 mm trim range allows for highly variable end-stops and rapid product-size changeovers on a line, which is far more versatile than using a fixed-stroke SAI cylinder. For exact ISO 15552 replacement matching, verify the 115 mm stroke, 100 mm adjustment, PT port thread, SUS304 rod, and the -S magnet requirement.
If your setup needs to hold a load securely without continuous live air, a standard SAIJ will not suffice since the rear adjuster is only a stop. You would need to look at the SAIL air-released lock or BSAI clamp-lock variants instead. Additionally, the 25 mm rod diameter handles side loads well, but any stroke approaching 300 mm or more will still require an external guide to prevent rod deflection.
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 SAIJ80 Adjustable Cylinder SAIJ80BX115-100S FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw lets you mechanically shorten the 115 mm nominal stroke by up to 100 mm, giving you an adjustable usable travel window of 15 to 115 mm. The adjuster functions as a travel stop for end-position tuning and is not a locking mechanism.
