About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX155-10
The AirTAC SAIJ80X155-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 145 to 155 mm, allowing you to dial back the nominal 155 mm stroke by up to 10 mm during commissioning.
Built for demanding environments, this variant uses a SUS304 stainless steel rod for superior corrosion resistance. It features PT tapered ports and dual sensor grooves on the extruded aluminum barrel. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without adding external stops.

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 SAIJ80BX155-10 Is Used
Machine Setup & Commissioning
Fine-tune the end position during initial setup using the 10 mm rear adjuster, achieving exact 145-155 mm travel without external stopper hardware.
Product Size Changeovers
Quickly adapt the cylinder stroke on packaging lines when product dimensions change, dialing back the stroke to accommodate varying package sizes.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX155-10 the Right Cylinder?
Choose this 80 mm bore when an application requires substantial thrust, such as 2513 N at 0.5 MPa, but needs less travel than the larger 100 mm bore which yields 3927 N. The 10 mm adjustment range is ideal for product changeovers, letting operators trim the end position by up to 10 mm without swapping cylinders. For fixed travel needs without commissioning tweaks, the standard SAI cylinder is a simpler alternative.
This model uses PT ports and a SUS304 rod. It supports mounting sets Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the stroke is under 300 mm, side-load risks are moderate, but the 25 mm rod and M20x1.5 thread handle standard loads well. Remember, the rear adjuster is a travel stop, not a lock; for load-holding without live air pressure, use an SAIL or BSAI cylinder.
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 SAIJ80BX155-10 FAQ
At the maximum 1.0 MPa pressure, it delivers up to 513 kgf.
The rear adjuster screw lets you mechanically shorten the effective stroke from 155 mm down to 145 mm. This creates a 10 mm adjustable window for fine-tuning end positions at commissioning without replacing the cylinder.
