About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX185-75
The AirTAC SAIJ80X185-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 110-185 mm usable travel window. The SUS304 stainless steel rod provides high corrosion resistance, while the PT tapered port threads ensure a robust, leak-free pneumatic connection.
This adjustable model lets you fine-tune the retract end-position at commissioning without swapping the cylinder or adding external stops. It features variable air cushions at both ends to decelerate the load, but the adjuster is a travel stop, not a lock. For load-holding without live air pressure, consider an AirTAC SAIL or BSAI series cylinder.

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 SAIJ80BX185-75 Is Used
Product Changeover
Dial in the exact retract position within the 110-185 mm window when switching between product sizes on a packaging line, avoiding manual stop adjustments.
Machine Setup
Fine-tune the end-of-stroke position during commissioning to perfect a pressing or clamping operation without machining new spacer blocks.
Variable End Stops
Adjust the travel distance on the fly for a diverter arm or sorting gate that needs to accommodate boxes of varying dimensions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX185-75 the Right Cylinder?
Choose this 80 mm bore when you need substantial thrust (2513 N at 0.5 MPa) and the ability to dial in a specific travel distance within a 110-185 mm window. If your application requires less force and a shorter adjustment range, stepping down to a 63 mm bore yields 1559 N. The large 75 mm adjustment range is perfect for accommodating product size changes on a line. To replace an ISO 15552 cylinder, match the 80 mm bore, 185 mm stroke, 75 mm adjustment, PT port thread, and standard mounting options (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because this is a 185 mm stroke, ensure external guiding for any heavy side loads.
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 SAIJ80BX185-75 FAQ
At the maximum pressure of 1.0 MPa, it delivers up to 513 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from its 185 mm nominal length down to as little as 110 mm. This provides a 75 mm tuning window to set the exact end position without replacing the cylinder.
