Airtac SAIJ80 Adjustable Cylinder SAIJ80BX145-10S
The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX145-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 145mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX145-10S
By turning the external stopper screw, you can fine-tune the effective travel down by up to 10mm, creating a precise 135-145mm usable stroke window for exact end-position calibration during commissioning. This configuration features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for position sensing.
The extruded aluminum barrel integrates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. Fluid supply connects via PT tapered G3/8 ports, and the unit omits heavy tie-rod construction in favor of an ISO 15552 profile design. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, 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 | — |
| 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 SAIJ80BX145-10S Is Used
Machine Changeover Calibration
Dial in the 135-145mm travel window during product size transitions without physically swapping out the entire cylinder assembly.
End-Stop Trimming
Use the 10mm rear adjuster to fine-tune the final retracted position, compensating for mechanical wear or slight fixture misalignment.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX145-10S the Right Cylinder?
If you need less force, stepping down to a 63mm bore yields 1559N at 0.5MPa; stepping up to a 100mm bore provides 3927N. The adjustable stroke is ideal for product changeovers on a line, allowing you to dial in the 135-145mm travel window on the fly rather than swapping a fixed-stroke SAI cylinder.
Remember that the rear adjuster acts purely as a travel stop to set deceleration endpoints, not as a locking device. A plain SAIJ cylinder cannot hold a load without live air pressure. For true fail-safe load holding, select an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder. To match this ISO 15552 replacement, specify: 80mm bore, 145mm stroke, 10mm adjustment, PT G3/8 ports, SUS304 rod, -S magnet, and standard mounting accessories.
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 SAIJ80BX145-10S FAQ
The rear external stopper screw allows you to shorten the nominal 145mm stroke by up to 10mm, providing an adjustable 135-145mm travel window. It functions as a mechanical stop to set the end position, but it is not a lock and will not hold the load without continuous air pressure.
