About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-75S
The AirTAC SAIJ100X165-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 90 to 165 mm. It delivers a robust 3927 N of push force at 0.5 MPa, making it suitable for heavy-duty positioning tasks. This unit includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors, and features an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance.
The integrated rear stopper mechanism allows technicians to fine-tune the retract end position during commissioning without swapping out the entire cylinder or adding external stops. It utilizes a PT tapered port thread and includes variable air cushions at both ends to decelerate the load smoothly. Remember that this rear adjuster acts only as a travel stop, not a lock, so it will not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 90 to 165 mm window during machine commissioning to accommodate different material thicknesses without external stopper blocks.
Product Size Changeover
Quickly readjust the rear stopper on a packaging or handling line to process a new product size, reducing downtime and avoiding cylinder replacement.
Heavy-Duty Positioning
Leverage the 3927 N push force at 0.5 MPa alongside the SUS420J2 stainless steel rod to reliably move and position heavy fixtures in industrial environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-75S the Right Cylinder?
Selecting this 100 mm bore cylinder is appropriate when your application requires substantial thrust, such as 5497 N at 0.7 MPa, but demands flexible end-positioning within a 90 to 165 mm range. If your setup requires less force and a shorter adjustment window, stepping down to an 80 mm bore provides 2513 N at 0.5 MPa. Conversely, heavier loads up to 6136 N at 0.5 MPa would necessitate moving up to a 125 mm bore. Because the nominal stroke is 165 mm, an external guide is recommended to manage side loads and prevent excessive wear on the rod.
Choose this adjustable-stroke model over a fixed SAI cylinder when you need precise end-stop tuning for product changeovers or variable material sizes. To match this ISO 15552 interchangeable cylinder exactly, specify a 100 mm bore, 165 mm stroke, 75 mm adjustment, PT port, and the -S magnet. If your process requires true load-holding without continuous air pressure, consider the SAIL pneumatic lock or BSAI clamp-lock series instead, as the SAIJ adjuster is strictly a stop.

- ✓ 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 SAIJ100 Adjustable Cylinder SAIJ100AX165-75S FAQ
The rear adjusting screw acts as a mechanical stopper that lets you trim the effective stroke back by up to 75 mm. This creates a usable travel window of 90 to 165 mm, allowing you to fine-tune the end position at commissioning without changing the cylinder.
At 0.5 MPa it provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N. The maximum push force is 801 kgf at 1.0 MPa.
