About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-30
The AirTAC SAIJ80X190-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 160 to 190 mm, allowing you to dial back the nominal 190 mm stroke by up to 30 mm during commissioning. Delivering a robust 2268 N pull force at 0.5 MPa, it handles heavy positioning tasks with precision.
This model is equipped with a SUS304 stainless steel rod for corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |

| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |

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 SAIJ80BX190-30 Is Used
Machine Changeover
Dial in the exact 160-190 mm end-stop during product size changes without physically swapping the cylinder or adding shims.
Assembly Positioning
Leverage the 2268 N pull force to seat heavy components, using the rear screw to fine-tune the final clamping position.
Diversion Gates
Adjust the retract stroke by up to 30 mm on the fly to perfectly time product diversion on variable-speed lines.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-30 the Right Cylinder?
Choose this 80 mm bore when a 63 mm bore (1402 N pull at 0.5 MPa) is insufficient but a 100 mm bore (3681 N pull) is oversized. The 30 mm adjustment range is ideal for product changeovers, letting you fine-tune the retract end position without swapping the cylinder or adding external stops. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For dead-air load holding, consider an AirTAC SAIL or BSAI cylinder. Because this 190 mm stroke is under 300 mm, side-load risks are moderate, but an external guide is still recommended for heavy lateral 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 SAIJ80BX190-30 FAQ
At the maximum operating pressure of 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster screw acts as a mechanical stop that shortens the effective travel. For this model, it creates a 160 to 190 mm usable stroke window, allowing precise end-position tuning at commissioning without affecting the standard ISO 15552 footprint.
