About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX800-100
The AirTAC SAIJ80X800-100 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This unit is configured with a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without swapping components; it does not hold the load without live air pressure. For position holding without continuous air, an external pilot-operated check valve or a related SAIL lock cylinder is required.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80BX800-100 Is Used
Product Changeover
Dial in the 700-800mm travel window during format size changes on a packaging line without replacing the entire cylinder.
Variable End Stops
Fine-tune the retraction point of a heavy conveyor diverter by up to 100mm to accommodate varying pallet dimensions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX800-100 the Right Cylinder?
The adjustable 100mm window is ideal for product changeovers on a line, allowing variable end-stops without machining new hard stops. Because the 800mm stroke is lengthy, an external guide is strongly recommended to manage side loads and prevent rod binding, despite the sturdy 25mm rod diameter and M20x1.5 thread.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 80mm bore, 800mm stroke, 100mm adjustment, PT G3/8 port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that SAIJ omits FB, CA, CB, and CR mounts. This SKU lacks a magnet; adding a magnet (-S) enables CMSE reed or DMSE electronic solid-state sensors.
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 SAIJ80 Adjustable Cylinder SAIJ80BX800-100 FAQ
At 0.9 MPa, the push force increases to 4523N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke within a 700-800mm window. It only sets the travel end and does not lock or hold the load without live air pressure.
