About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX850-100S
The AirTAC SAIJ100X850-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. Because this SKU carries a -100 adjustment code, you can dial back the nominal 850mm travel to any effective length between 750 and 850mm during commissioning without swapping the cylinder or adding external stops.
This unit includes a -S magnet for use with AirTAC CMSE reed and DMSE electronic sensors, and features a SUS304 stainless steel rod for corrosion resistance. The extruded aluminum barrel provides sensor grooves on both sides. It uses PT tapered ports (G1/2) and offers variable air cushioning at both ends. Remember that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX850-100S Is Used
Variable End-Stop Machining
Fine-tune the 750-850mm stroke window on the fly to accommodate different part lengths during machining operations.
Product Changeover Lines
Quickly adjust the rear stopper during line changeovers to set new extended positions without replacing the entire cylinder.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX850-100S the Right Cylinder?
The adjustable 750-850mm window is ideal for product changeovers where exact end-positioning varies. It uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR mounts. To replace an ISO 15552 cylinder, match the 100mm bore, 850mm stroke, 100mm adjustment, PT G1/2 ports, and -S magnet.
Because the 850mm stroke is long, the 25mm rod still requires an external guide to prevent excessive side-loading. If your application requires true load-holding without continuous air pressure, the rear stopper here will not act as a brake; you should look at the SAIL (air-released lock) or BSAI (clamp-lock) series instead.
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 SAIJ100BX850-100S FAQ
The rear adjuster allows you to shorten the nominal 850mm stroke by up to 100mm, providing a usable travel window of 750 to 850mm. This stopper only sets the travel end and does not lock the load without live air.
