About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX165-75
The AirTAC SAIJ100X165-75 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 165 mm stroke that can be dialed back by up to 75 mm, giving you a precise 90-165 mm usable travel window for fine-tuning end positions during commissioning. In the 100 mm bore class, it delivers a robust 5497 N push force at 0.7 MPa, making it suitable for heavy-duty positioning tasks.
This variant is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Remember that the rear adjuster acts purely as a mechanical stop to set the travel limit, not as a lock, so it cannot hold a load without continuous live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX165-75 Is Used
Product Size Changeovers
Dial in the 90-165 mm stroke window instantly on the rear screw when adapting machinery to a new product length, bypassing the need to physically swap cylinders.
Heavy-Duty Positioning
Leverage the 5497 N push force at 0.7 MPa to move heavy jigs into exact alignment, using the rear stopper to guarantee precise retract endpoints.
Corrosive Assembly Lines
Rely on the SUS304 stainless steel rod for robust performance in humid or washdown manufacturing environments where standard carbon steel rods would degrade.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX165-75 the Right Cylinder?
Select this 100 mm bore cylinder when an application requires substantial force, such as 5497 N at 0.7 MPa, combined with variable end-stop positioning. If your setup needs less thrust, stepping down to an 80 mm bore yields 3518 N at 0.7 MPa, whereas moving up to a 125 mm bore provides 8590 N. The adjustable stroke is ideal for product changeovers on a line, allowing you to shift the retraction point without physically swapping the cylinder or adding external stops.
For an exact ISO 15552 replacement match, verify the 100 mm bore, 165 mm stroke, 75 mm adjustment range, PT port threads, and the SUS304 rod material. Note that this unit lacks a magnet, so it cannot host CMSE or DMSE sensors without a -S suffix. Because the 165 mm stroke is relatively short, side-load risks are minimal, but an external guide remains recommended for heavy off-center loads. If true load-holding is required without air pressure, consider an external rod lock or the AirTAC SAIL series instead of relying on the rear stopper.

- ✓ 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 SAIJ100BX165-75 FAQ
At a 0.7 MPa operating pressure, this 100 mm bore cylinder provides 5497 N of push force and 3681 N of pull force. It can achieve a maximum push force of 7068 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that shortens the 165 mm nominal stroke by up to 75 mm, creating a 90-165 mm usable travel window. It sets the end position but does not lock the load without live air pressure.
