About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX900-10S
The AirTAC SAIJ80X900-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 2513N of push force at 0.5 MPa. It features a SUS304 stainless steel rod and a PT tapered port. The integrated -S magnet enables precise position detection using AirTAC CMSE reed or DMSE electronic solid-state sensors housed within the dual-side barrel grooves.
With a nominal 900mm stroke and a 10mm adjustment range, this SKU provides an exact 890-900mm usable travel window. This fine-tuning capability allows you to dial in the retract end-position during commissioning without adding external stops. The adjuster acts purely as a travel stop for deceleration alongside the standard air cushions, meaning it will not hold a load without continuous live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX900-10S Is Used
Long-Stroke Machining
Provides the 890-900mm travel window needed to fine-tune the retract position on large machining centers without external stopper blocks.
Conveyor Changeover
Allows operators to quickly adjust the end-stop position by up to 10mm during product size changeovers on automated material handling lines.
Automated Assembly
Delivers 2513N of push force at 0.5 MPa for pressing or lifting tasks, with the rear screw enabling precise calibration during initial machine commissioning.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX900-10S the Right Cylinder?
Choose this 80mm bore when an application requires more thrust than a 63mm cylinder (which provides 1559N push at 0.5 MPa) but less bulk than a 100mm unit. The adjustable 890-900mm travel window is ideal for machine setups requiring exact end-position tuning without swapping cylinders. For a fixed end-stop, a standard SAI cylinder would suffice, but this SAIJ model saves time during product changeovers. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the stroke is 900mm, the 25mm rod and M20x1.5 thread still require an external guide to prevent excessive side-loading on the piston. Remember that the rear adjuster is a stop, not a lock; for load-holding without live air, consider an external rod lock or the SAIL series. To match this ISO 15552 cylinder, specify the 80mm bore, 900mm stroke, 10mm adjustment, PT ports, and -S magnet.

- ✓ 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 SAIJ80BX900-10S FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw allows you to shorten the effective stroke by up to 10mm, creating a usable travel window of 890-900mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
