About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX15-10S
It features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE or DMSE sensors. With a nominal 15mm stroke and a 10mm adjustment range, it provides a highly precise 5-15mm usable travel window for exacting short-stroke tasks.
This adjustable-stroke design allows you to fine-tune the retract end position at commissioning without adding external stops. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for position holding without pressure, consider an external rod lock or the SAIL series. It uses a PT tapered port and supports mounting options including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ80BX15-10S Is Used
Short-Stroke Clamping
Ideal for high-force clamping where the exact material thickness varies slightly, using the 5-15mm adjustable window to dial in the perfect grip without retooling.
Commissioning End-Tuning
Allows engineers to fine-tune the retract end position during initial machine setup, accommodating mechanical tolerances without swapping out the cylinder.
Product Changeover
Enables rapid adjustment of the end-stop on automated lines when switching between product sizes, minimizing downtime and maximizing line flexibility.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX15-10S the Right Cylinder?
The adjustable 5-15mm travel window is ideal for applications requiring precise variable end-stops during machine setup or product changeover, replacing the need for fixed-stroke SAI cylinders when exact positioning is not yet finalized.
Because the stroke is under 300mm, side-load stress on the 25mm rod is minimal, though external guiding is still recommended for heavy lateral loads. To match this ISO 15552 interchangeable cylinder exactly, specify the 80mm bore, 15mm nominal stroke, 10mm adjustment, PT ports, SUS304 rod material, and the -S magnet option.
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 SAIJ80BX15-10S FAQ
The rear adjuster screw allows you to trim the effective stroke by up to 10mm. With the 15mm nominal stroke, this creates a usable travel window of 5-15mm, letting you set the exact end position without changing the cylinder.
