About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX150-50
The AirTAC SAIJ80X150-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The built-in rear stopper allows you to dial back the nominal 150mm stroke by up to 50mm, creating a precise 100-150mm usable travel window for product changeovers without adding external stops.
This adjustable-stroke design is ideal for fine-tuning end positions at commissioning. It includes variable air cushions at both ends (36mm cushion length) for smooth deceleration. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for load-holding without pressure, consider the SAIL or BSAI series. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting.

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 SAIJ80BX150-50 Is Used
Product Changeover
Dial in the 100-150mm travel window during format changes on packaging lines to accommodate varying carton sizes without swapping cylinders.
Commissioning Tuning
Fine-tune the exact retract end-position during machine setup to align tooling perfectly, preventing the need for external mechanical stops.
Variable Diverting
Adjust the stroke on the fly for sorting or diverting applications on conveyors where product lengths vary and require different extension depths.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX150-50 the Right Cylinder?
If you need less force, stepping down to a 63mm bore yields 1559N at 0.5 MPa. The 50mm adjustment window is particularly useful for machinery processing varying product sizes, replacing the need to swap out a fixed-stroke SAI cylinder during format changes.
When ordering, confirm the configuration: 80mm bore, 150mm nominal stroke, 50mm adjustment range, PT tapered port (G3/8), and SUS304 stainless steel rod (code B). Because the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) omits FB, CA, CB, and CR options, verify your mounting interface. As this cylinder lacks a magnet (-S), it cannot use AirTAC CMSE or DMSE 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 SAIJ80BX150-50 FAQ
The pull force is 2268N at 0.5 MPa.
The rear adjuster screw allows you to reduce the nominal 150mm stroke by up to 50mm, providing a usable travel window of 100-150mm. This stopper sets the end position but does not lock or hold the load without live air pressure.
