About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX165-100
The AirTAC SAIJ80X165-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 65-165 mm usable travel window. The adjustable stopper allows precise end-position tuning during commissioning without adding external stops.
This model uses variable air cushions at both ends and operates at speeds of 30-800 mm/s. The rear adjuster functions strictly as a travel stop to set deceleration, not as a load-holding lock; position holding without live air requires a SAIL or BSAI variant. It supports mounting sets Basic, FA, LB, TC, FTC, TCM1 and TCM2.

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 SAIJ80BX165-100 Is Used
Variable End-Stop Positioning
Dial in precise retract distances between 65 and 165 mm for multi-product lines without physically swapping the cylinder or adding external mechanical stops.
Machine Setup & Changeover
Speed up product size transitions on automated machinery by turning the rear adjuster to instantly tune the end-of-stroke position to the new part dimensions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX165-100 the Right Cylinder?
Choose this 80 mm bore when an application requires high thrust but variable end-stops for product changeovers, stepping up from a 63 mm bore that offers 1402 N pull at 0.5 MPa. The generous 100 mm adjustment range is ideal for adapting machinery to different part sizes on the fly. For holding loads safely without continuous air pressure, select a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead of relying on the SAIJ adjuster.
To match this ISO 15552 replacement, verify the 80 mm bore, 165 mm stroke, 100 mm adjustment, PT port thread, and standard non-magnet configuration. Because the stroke is under 300 mm, side-load concerns are minimal, though the 25 mm rod thread handles standard loads effectively.
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 SAIJ80BX165-100 FAQ
At the maximum 1.0 MPa pressure, it delivers up to 513 kgf.
The rear adjuster acts as a stopper that lets you trim the effective travel back from the 165 mm nominal stroke, creating a 65-165 mm usable window. It sets the travel end and deceleration point, but it does not lock or hold the load without continuous air pressure.
