About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX115-100
The AirTAC SAIJ80X115-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 115 mm travel by up to 100 mm. This creates a highly versatile 15 to 115 mm usable stroke window, perfect for adapting end positions on the fly without swapping out the barrel.
Unlike fixed-stroke actuators, the rear stopper screw lets you fine-tune the retract end during commissioning. The adjuster functions purely as a travel stop and works alongside the standard variable air cushions to decelerate the load; it does not lock the payload in place without live air pressure. For load-holding without continuous air, an external pilot-operated check valve or a related AirTAC BSAI clamp-lock cylinder is required.

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 SAIJ80BX115-100 Is Used
Product Changeover
Quickly modify the extended stop position on a packaging line when switching to a different box size, utilizing the 100 mm adjustment window to avoid changing cylinders.
Prototype Positioning
Dial in the exact end-of-stroke location during machine commissioning, allowing precise mechanical tuning without needing custom spacers or external stops.
Variable End Stops
Accommodate multiple stroke lengths on a single fixture by setting the rear stopper screw anywhere within the 15 to 115 mm travel window for flexible manufacturing.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX115-100 the Right Cylinder?
Choose this 80 mm bore actuator when an application demands high force (up to 4523 N at 0.9 MPa) alongside extreme stroke flexibility. If your setup only requires a fixed travel distance and lower thrust, stepping down to a 63 mm bore yields 2805 N at 0.9 MPa, whereas heavier payloads might necessitate a 100 mm bore providing 7068 N. The massive 100 mm adjustment range on this SKU is ideal for prototyping or production lines running multiple product sizes, replacing the need to stock numerous fixed-length SAI cylinders.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 115 mm nominal stroke, 100 mm adjustment code, PT tapered port thread, and standard mounting interface. This actuator supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the usable travel can be dialed down to 15 mm, ensure your external guide rails accommodate the specific adjusted length to prevent rod side-loading.
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 SAIJ80BX115-100 FAQ
The pull force is 2268 N at 0.5 MPa and 4523 N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that shortens the 115 mm nominal stroke by up to 100 mm, creating a usable travel window of 15 to 115 mm. It sets the end position but does not hold the load without live air pressure.
