About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX20-10S
The AirTAC SAIJ80X20-10-S is a double-acting ISO 15552 profile cylinder featuring a rear mechanical adjuster that allows you to shorten the nominal 20 mm stroke by up to 10 mm. This creates a highly specific 10 to 20 mm usable travel window, enabling precise end-position tuning at commissioning without swapping out the unit. Equipped with a SUS304 stainless steel rod and a -S magnet, it integrates seamlessly with AirTAC CMSE reed and DMSE electronic sensors for exact position feedback.
Delivering robust performance, this 80 mm bore model generates 2268 N of pull force at 0.5 MPa and operates at speeds between 30 and 800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, and fluid supply is routed through PT tapered G3/8 ports. It is important to note that the rear adjuster functions strictly as a travel stop for deceleration, not as a lock; the cylinder cannot hold loads without live air pressure.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |

| 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 SAIJ80BX20-10S Is Used
Precision End-Stop Tuning
Dial in the exact 10 to 20 mm travel window during machine commissioning to accommodate varying material thicknesses without physically replacing the cylinder.
Rapid Product Changeover
Quickly adjust the rear stopper screw on the production line when switching between different product sizes, minimizing downtime and avoiding external stop hardware.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX20-10S the Right Cylinder?
Choose this 80 mm bore adjustable-stroke cylinder when your application requires heavy force but variable end-stops for product changeovers. If your setup needs less force, stepping down to a 63 mm bore yields 1402 N of pull force at 0.5 MPa, whereas moving up to a 100 mm bore provides 3681 N. The SAIJ80X20-10-S is selected over a fixed-stroke SAI model specifically to fine-tune the travel end during machine setup without adding external stops.
For dimensionally interchangeable ISO 15552 replacements, match the 80 mm bore, 20 mm nominal stroke, 10 mm adjustment range, PT G3/8 ports, SUS304 rod, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Since the stroke is under 300 mm, side-load concerns are minimal, but always ensure the load is guided to prevent rod binding. For applications requiring true load-holding without live air, consider the SAIL or BSAI series instead.

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 SAIJ80BX20-10S FAQ
The rear adjuster acts as a mechanical stopper that lets you shorten the 20 mm nominal stroke by up to 10 mm, creating a usable travel window of 10 to 20 mm. It only sets the travel end and deceleration; it does not lock the load without live air pressure.
It operates at speeds ranging from 30 to 800 mm/s.
