About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-10
The AirTAC SAIJ100X175-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to fine-tune the retract end position during commissioning. It provides a usable travel window of 165 to 175 mm, allowing precise variable end-stops without swapping out the unit. In the 100 mm bore class, it delivers 3927 N of push force and 3681 N of pull force at 0.5 MPa.
This SKU is configured with a SUS420J2 stainless steel rod (code A) for enhanced durability against side loads and a PT tapered port thread. The extruded aluminum barrel features sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-10 Is Used
Machine Setup Fine-Tuning
Dial in the exact 165 to 175 mm retract position during initial machine commissioning without adding external mechanical stops.
Product Size Changeover
Quickly adapt the cylinder's end-stop for varying product lengths on a packaging line using the 10 mm adjustment range.
Heavy-Duty Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy jigs into place while relying on the adjuster to set the precise resting point.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-10 the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (providing 2513 N push at 0.5 MPa) is insufficient for your load, but you want to avoid the heavier 125 mm class. The 10 mm adjustment range is ideal for product changeovers that require a slight shift in the end-of-stroke position. Since the nominal stroke is 175 mm, an external guide is not strictly necessary, but the robust 25 mm rod and M20x1.5 thread handle high side loads well.
If you need to hold a load without continuous live air pressure, note that the rear adjuster acts only as a travel stop and the air cushion provides deceleration, neither functions as a lock. For secure load-holding, consider the SAIL or BSAI cylinder series instead. This model is dimensionally interchangeable per ISO 15552, matching the bore, stroke, PT port, and mounting footprint.
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 SAIJ100AX175-10 FAQ
The rear adjuster acts as a mechanical stopper that lets you shorten the effective stroke by up to 10 mm, creating a usable travel window of 165 to 175 mm. It allows fine-tuning of the end position without replacing the cylinder.
At 0.5 MPa, it provides a push force of 3927 N and a pull force of 3681 N. At 0.9 MPa, the push force increases to 7068 N.
