About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-50
The AirTAC SAIJ100X165-50 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 165 mm stroke that can be fine-tuned backward by up to 50 mm, yielding a usable travel window of 115 to 165 mm. This allows precise end-position calibration during commissioning without swapping out the physical actuator. The extruded aluminum barrel features dual sensor grooves, and this specific configuration utilizes a SUS420J2 stainless steel rod for enhanced corrosion resistance.
Delivering 5497 N of push force at 0.7 MPa, this 100 mm bore actuator handles substantial loads. The PT tapered porting is G1/2, and the unit includes variable air cushions at both ends to manage kinetic energy. The rear stopper screw acts strictly as a travel limiter to set the retraction end-point; it is not a locking mechanism and will not hold a load without continuous live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-50 Is Used
Product Changeovers
Dial in the 115-165 mm travel window during format size changes on a packaging line, using the rear screw to set new retraction endpoints rapidly.
Machine Setup
Fine-tune the end-of-stroke position during initial commissioning without machining external stopper blocks or changing the cylinder.
Variable End Stops
Accommodate multiple part sizes on a single fixture by adjusting the retraction depth up to 50 mm to suit different workpiece heights.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-50 the Right Cylinder?
Select this 100 mm bore cylinder when your application requires 5497 N push force at 0.7 MPa, stepping up from an 80 mm bore that provides 3518 N. The 50 mm adjustment range is ideal for production lines needing rapid product-size changeovers, replacing the need to bolt on external physical stops. For an exact ISO 15552 replacement match, verify the 165 mm stroke, 50 mm adjustment code, PT port threads, and your required mounting bracket from the available SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
Because the 165 mm stroke is relatively short for this bore size, side-load stress on the 25 mm rod is minimal, though external guiding remains best practice for heavy offset loads. If your process demands true load-holding without live air pressure, a standard SAIJ is insufficient; consider an AirTAC SAIL with an air-released lock or a BSAI clamp-lock cylinder instead. Note that this SKU is supplied without a magnet, so position sensing via CMSE or DMSE switches is not supported without a model change.
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 SAIJ100 Adjustable Cylinder SAIJ100AX165-50 FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder provides a push force of 5497 N and a pull force of 3681 N. At the maximum 1.0 MPa pressure, it achieves 801 kgf.
The rear adjuster screw allows you to shorten the 165 mm nominal stroke by up to 50 mm, creating a usable travel window of 115 to 165 mm. This stopper only limits the travel end and does not lock the load without air pressure.
