About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX225-30
The AirTAC SAIJ80X225-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window down to 195-225 mm without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
This SUS304 stainless steel rod variant (code B) provides enhanced resistance to corrosion and external debris. The rear adjuster functions strictly as a travel stop for commissioning precision, not a lock, meaning live air is required to hold the load. It uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

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 SAIJ80BX225-30 Is Used
Machine Setup & Changeover
Dial in the 195-225 mm travel window during commissioning to perfectly set the end position for new product runs without swapping hardware.
Variable End-Stop Positioning
Use the rear adjuster to fine-tune the retract distance on the fly, accommodating different material thicknesses or tooling offsets.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod for reliable actuation in washdown or mildly corrosive manufacturing environments.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX225-30 the Right Cylinder?
Choose this 80 mm bore when you need significantly more force than the 63 mm class offers (1402 N pull at 0.5 MPa) but less than the 100 mm class. The 30 mm adjustment range is perfect for product changeovers, letting you dial in the exact end position without swapping cylinders. For load-holding without continuous air pressure, this cylinder will not suffice; you should explore the SAIL or BSAI series instead.
Because the 225 mm stroke exceeds 300 mm? No, but if you scale up to longer strokes, always support the load with an external guide to prevent excessive side-loading on the 25 mm rod. To replace an ISO 15552 cylinder, match the 80 mm bore, 225 mm stroke, 30 mm adjust, PT G3/8 port, and your desired mounting bracket.
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 SAIJ80BX225-30 FAQ
The operating speed range is 30-800 mm/s.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 225 mm nominal stroke by up to 30 mm, creating a 195-225 mm usable travel window. It is a stop, not a lock.
