About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX500-10
The AirTAC SAIJ80X500-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the nominal 500 mm stroke down by up to 10 mm. This creates a precise 490-500 mm usable travel window, enabling exact end-position calibration during commissioning without swapping hardware.
Because the adjustment mechanism acts purely as a retract-end stopper to set the travel limit, it does not lock or hold the load without live air pressure. The extruded aluminum barrel incorporates sensor grooves on both sides, ready for AirTAC CMSE reed and DMSE electronic switches if position feedback is required later. It supports standard variable air cushions at both ends to decelerate the motion smoothly.

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 SAIJ80BX500-10 Is Used
Variable End-Stop Tuning
Dial in the exact 490-500 mm retract position during machine setup to accommodate new product dimensions without changing the cylinder.
Product Changeover Systems
Quickly adjust the stroke end on packaging lines to handle different package lengths on the fly, minimizing downtime.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX500-10 the Right Cylinder?
The adjustable stroke is ideal for production lines handling slight product size variations, letting you dial in the exact end-stop on the fly instead of machining external spacers. For any application using a 500 mm stroke, ensure you use an external guide rail to prevent excessive side-loading on the 25 mm rod.
When specifying an ISO 15552 replacement match, confirm the 80 mm bore, 500 mm stroke, 10 mm adjustment range, PT G3/8 port, and SUS304 rod material. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. If your process requires true fail-safe load holding without live air, this cylinder is not a lock; you should pivot to the SAIL or BSAI series instead.

- ✓ 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 SAIJ80BX500-10 FAQ
It can deliver a maximum of 513 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that trims the effective travel, providing a 490-500 mm usable window. It sets the end position but does not hold the load without continuous air pressure.
