About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX165-50
The AirTAC SAIJ80X165-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 165 mm travel by up to 50 mm. This creates a usable stroke window of 115 to 165 mm, providing exact end-position tuning at commissioning without swapping hardware.
Built with a SUS304 stainless steel rod for superior corrosion resistance, this model features a PT tapered G3/8 port. The extruded aluminum barrel includes sensor grooves on both sides. The rear adjuster functions purely as a travel stop for deceleration alongside the standard air cushions, meaning it will not hold the load without continuous live air pressure.

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 SAIJ80BX165-50 Is Used
Variable End-Stop Setup
Dial in the exact 115 to 165 mm travel distance during machine commissioning to accommodate different product dimensions without adding external physical stops.
Changeover Fine-Tuning
Rapidly adjust the retract position on packaging lines during format changes, using the 50 mm rear trim range to perfectly set the stopping point.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX165-50 the Right Cylinder?
The 50 mm adjustment range is ideal for product-size changeovers on a line, letting operators set variable end stops rapidly. For position holding without live air, consider an AirTAC SAIL or BSAI cylinder, or use an external rod lock. To replace an ISO 15552 cylinder, match the 80 mm bore, 165 mm stroke, 50 mm adjustment, PT G3/8 port, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting set. The 25 mm rod and M20x1.5 thread handle high side loads, but any stroke of 300 mm or more requires an external guide.

- ✓ 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 SAIJ80BX165-50 FAQ
At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster acts as a mechanical stop that trims the 165 mm nominal stroke back by up to 50 mm, creating an adjustable travel window of 115 to 165 mm. It only sets the end position and does not lock the load.
