About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-30S
The AirTAC SAIJ80X190-30-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 160-190 mm, allowing you to dial back the nominal 190 mm stroke by up to 30 mm during commissioning.
This extruded aluminum barrel design omits tie-rods and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) compared to standard ISO cylinders. The rear adjuster acts strictly as a mechanical stop for end-position tuning; it does not lock the load without 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 SAIJ80BX190-30S Is Used
Product Changeover Setup
Quickly fine-tune the 160-190 mm end-stop during format size changes on packaging lines without replacing the cylinder.
Variable End-Stop Positioning
Dial in the exact retract distance for multi-stage tooling operations where the effective stroke must adapt to different part depths.
Automated Clamping Stations
Use the 2513 N pull force at 0.5 MPa to secure workpieces, relying on the rear stop to prevent over-travel during the clamp cycle.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-30S the Right Cylinder?
Choose this 80 mm bore when you need higher thrust than a 63 mm bore (which provides 2182 N at 0.7 MPa) but want to avoid the bulk of a 100 mm unit. The adjustable stroke is ideal for machine changeovers where exact end-of-stroke positioning varies slightly, saving you from swapping cylinders or adding external stops. For applications requiring the cylinder to hold a load safely without continuous air pressure, select the SAIL or BSAI series instead, as the SAIJ adjuster is not a locking device.
This configuration includes a PT tapered port thread, an M20x1.5 rod thread, and 36 mm cushions at both ends. Operating speed ranges from 30-800 mm/s. Although the 190 mm stroke is standard, always ensure proper guiding for any long unsupported loads to prevent side-load damage to the rod.
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 SAIJ80BX190-30S FAQ
The rear adjuster screw allows you to shorten the effective travel from the 190 mm nominal stroke down to 160 mm. This creates a 30 mm tuning window for precise end-position setup without needing external stops.
The maximum thrust is 513 kgf at 1.0 MPa.
