About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX220-30
The AirTAC SAIJ80X220-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end position. It provides a usable travel window of 190 to 220 mm, letting you dial back the nominal 220 mm stroke by up to 30 mm during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This unit is built with a SUS304 stainless steel rod for corrosion resistance and uses a PT tapered G3/8 port. It supports speeds of 30-800 mm/s and relies on variable air cushions at both ends to decelerate the load.

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 SAIJ80BX220-30 Is Used
Machine Setup & Changeover
Fine-tune the 190-220 mm travel window during product size changes without physically swapping cylinders or bolting on external mechanical stops.
Variable End-Stop Positioning
Dial in the exact retract position on packaging lines, allowing up to 30 mm of precise adjustment to accommodate varying package dimensions on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX220-30 the Right Cylinder?
Choose this 80 mm bore when 50 mm (982 N at 0.5 MPa) is too weak but 100 mm (3927 N at 0.5 MPa) is oversized. The adjustable stroke is ideal for product changeovers on a line, letting you shift the end stop by up to 30 mm rather than swapping a fixed-stroke SAI cylinder. To match this ISO 15552 replacement, specify the 220 mm stroke, 30 mm adjustment, PT G3/8 port, and SUS304 rod material.
Because the nominal stroke is 220 mm, you should ensure adequate external guidance for long unsupported loads to prevent side-loading damage. Remember that the rear adjuster is a travel stop, not a lock; the SAIJ80X220-30 will not hold its position without live air pressure. For true load-holding, select a SAIL or BSAI series cylinder instead.
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 SAIJ80BX220-30 FAQ
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back from the 220 mm nominal stroke by up to 30 mm, creating a 190-220 mm usable window. It only sets the end position; it does not lock the load without continuous air pressure.
