About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX165-30S
The AirTAC SAIJ100X165-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 100mm bore and a 165mm nominal stroke that can be fine-tuned down by 30mm, providing an exact 135-165mm usable travel window for precise retract-end positioning. With a robust 25mm piston rod and G1/2 porting, it generates 3927N of push force and 3681N of pull force at 0.5 MPa.
This variant includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and is built with a -S magnet for seamless position detection using AirTAC CMSE reed or DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and mounting is supported via a reduced ISO 15552 subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX165-30S Is Used
Precision End-Stop Tuning
Dial in the exact 135-165mm retract position during machine commissioning to perfect a pressing or clamping operation without machining custom spacers.
Product Line Changeover
Quickly adapt the cylinder's effective travel window when switching the production line to a new product size, minimizing downtime and avoiding cylinder swaps.
Stainless Rod Guiding
Leverage the 25mm SUS304 stainless steel rod for corrosion-resistant actuation in packaging or processing environments that require precise, adjustable end positions.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX165-30S the Right Cylinder?
Choose this 100mm bore adjustable cylinder when your machine setup requires variable end-stops or frequent product-size changeovers, allowing you to dial in the 135-165mm travel window without swapping hardware or adding external stops. If your application requires less force, stepping down to an 80mm bore yields 2513N of push force at 0.5 MPa, while upgrading to a 125mm bore provides 6136N for heavier loads.
Because the 165mm stroke is below the 300mm side-load threshold, the 25mm rod handles standard guiding well, though an external guide is still recommended for heavy lateral loads. To directly replace an ISO 15552 cylinder, match the 100mm bore, 165mm stroke, 30mm adjustment, PT tapered ports, and the -S magnet. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider the SAIL or BSAI series.
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 SAIJ100BX165-30S FAQ
At a 0.5 MPa operating pressure, this 100mm bore cylinder generates 3927N of push force and 3681N of pull force. It can reach a maximum thrust of 801 kgf at 1.0 MPa.
The rear external adjuster screw allows you to shorten the effective travel from the nominal 165mm down to 135mm. This creates a 135-165mm usable window for fine-tuning the end position at commissioning, but it functions only as a stop and does not lock the load without live air pressure.
