About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX165-100
The AirTAC SAIJ100X165-100 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 100 mm adjustment range, allowing you to trim the 165 mm nominal stroke back to a 65 mm minimum, creating a 65-165 mm usable travel window. In the 100 mm bore class, it delivers 3927 N of push force and 3681 N of pull force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This SKU features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance and features PT tapered port threads (G1/2). The extruded aluminum barrel includes sensor grooves on both sides. Note that the rear adjuster acts purely as a travel stop to fine-tune the end position during commissioning; it does not lock or hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX165-100 Is Used
Variable Product Changeover
Dial in the stroke from 165 mm down to 65 mm during product size transitions on a packaging line, eliminating the need to physically swap cylinders for different package lengths.
Commissioning End-Stop Tuning
Fine-tune the exact retract position during machine setup using the rear screw, absorbing mechanical tolerances without fabricating custom external stopper blocks.
Heavy Payload Positioning
Leverage the 3927 N push force at 0.5 MPa to push heavy pallets or chassis into a workstation, relying on the rear stopper to set the precise indexing depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX165-100 the Right Cylinder?
Select this 100 mm bore cylinder when your application requires substantial thrust (3927 N push at 0.5 MPa) alongside flexible end-position tuning. If your process requires less force, stepping down to an 80 mm bore yields 2513 N of push force, but the 100 mm class is necessary for heavier payloads. The 100 mm adjustment range is ideal for machines processing varied product sizes, allowing you to reconfigure the travel end-stop on the fly without swapping the cylinder or adding external mechanical stops.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 165 mm stroke, PT port threads, and the chosen mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Because the SAIJ mounting set omits FB, CA, CB, and CR options, verify your bracket compatibility. As a double-acting cylinder, it will not hold its position if air pressure drops; for true load-holding without live air, consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead.

- ✓ 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 SAIJ100BX165-100 FAQ
The rear adjuster acts as an external stopper that limits the piston's retraction. For this model, you can trim the 165 mm nominal stroke back by up to 100 mm, giving you a usable travel window of 65 to 165 mm. It sets the travel end but does not lock the load without live air pressure.
At 0.5 MPa operating pressure, the SAIJ100X165-100 provides 3927 N of push force and 3681 N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 801 kgf.
