About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-20S
The AirTAC SAIJ80X230-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the nominal 230 mm travel back by up to 20 mm, yielding a precise 210-230 mm usable window. It delivers robust thrust, pushing 4523 N and pulling 2268 N at 0.9 MPa. The stainless SUS304 rod material offers high corrosion resistance for harsh environments.
This unit includes a magnet for position sensing via CMSE reed or DMSE electronic switches. It uses a PT G3/8 port and M20x1.5 rod thread. The rear adjuster acts purely as a travel stop to fine-tune end positions without adding external stops. It supports the SAIJ mounting subset: 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 SAIJ80BX230-20S Is Used
Machine Setup Calibration
Dial in the exact 210-230 mm end-stop during commissioning to perfect positioning without machining external stop blocks.
Product Size Changeover
Quickly trim the retract distance up to 20 mm on packaging lines when switching to different box lengths.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-20S the Right Cylinder?
The 20 mm adjustment range is ideal for product changeovers, letting you dial in the exact end-of-stroke without swapping the cylinder. For load-holding without live air, this adjuster is not a lock; consider SAIL or BSAI types instead.
At 230 mm stroke, the M20x1.5 rod handles side loads well, but an external guide is recommended for heavy loads. This SAIJ variant is dimensionally interchangeable per ISO 15552. Exact specs: 80 mm bore, 230 mm stroke, 20 mm adjust, PT G3/8 port, SAIJ mounting set, -S magnet included.
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 SAIJ80BX230-20S FAQ
A rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective travel from 230 mm down to 210 mm. This stop only sets the end position; it does not lock the load without live air pressure.
