About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX220-75S
The AirTAC SAIJ80X220-75-S is a double-acting ISO 15552 profile cylinder featuring a built-in rear stroke adjuster. It provides a nominal 220 mm stroke that can be dialed back by up to 75 mm, yielding a usable travel window of 145-220 mm for precise end-position tuning.
This specific configuration includes a SUS304 stainless steel rod for corrosion resistance and a magnetic piston (-S) for electronic or reed switch sensing. The extruded aluminum barrel incorporates sensor grooves on both sides, and the pneumatic design uses PT tapered port threads (G3/8) alongside adjustable air cushions at both ends to manage deceleration.

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 SAIJ80BX220-75S Is Used
Variable End-Position Setup
Dial in the retract distance from 145 to 220 mm during machine commissioning to accommodate different material thicknesses without swapping cylinders.
Product Size Changeover
Quickly adjust the stroke stop on packaging lines when transitioning between varying package dimensions, minimizing downtime.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for robust push force in manufacturing environments where moisture or minor splashing is present.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX220-75S the Right Cylinder?
Select this 80 mm bore model when an application requires substantial thrust but variable end-stops during product changeovers. If you need less force, stepping down to a 63 mm bore yields 1402 N of pull at 0.5 MPa, whereas stepping up to 100 mm provides 3681 N of pull. The 75 mm adjustment range allows you to fine-tune the retract position at commissioning without adding external physical stops.
Because the 220 mm stroke exceeds 300 mm? No, but for any stroke of 300 mm or more, an external guide is recommended to manage side-load. Remember that the rear adjuster functions strictly as a travel stop and does not hold the load without live air pressure; for true drop-prevention, consider a SAIL or BSAI series cylinder. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552.
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 SAIJ80BX220-75S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 220 mm down to 145 mm. This provides a 75 mm adjustable window for fine-tuning the end position at commissioning without external stops.
The rear adjuster and air cushions only set and decelerate the travel end; they do not lock the load. For position holding without live air pressure, use a SAIL or BSAI cylinder.
