About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX475-10
The AirTAC SAIJ80X475-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 465-475 mm usable travel window, letting you fine-tune the retract end-position by up to 10 mm during commissioning. Using a 25 mm piston rod and G3/8 ports, it delivers substantial thrust, yielding 4523N of push force at 0.9 MPa.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance in humid or washdown environments. The extruded aluminum barrel incorporates sensor grooves on both sides for CMSE reed or DMSE solid-state switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX475-10 Is Used
Machine Changeover
Dial in the 465-475 mm retract position during product size changes without physically shimming the cylinder mount.
End-Stop Tuning
Fine-tune the final 10 mm of travel to perfect a pressing or clamping operation during initial commissioning.
Corrosive Environments
Leverage the SUS304 stainless steel rod for reliable actuation in food processing or humid manufacturing lines.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX475-10 the Right Cylinder?
Choose this 80 mm bore when an application requires more power than the 63 mm variant, which offers 2805N of push force at 0.9 MPa. The 10 mm rear adjuster acts as a mechanical stop to dial in the exact end position without swapping cylinders or adding external stops. Note that this adjuster and the air cushions do not hold the load without live air; for position holding, select a SAIL or BSAI cylinder. Because the 475 mm stroke is long, an external guide is recommended to prevent excessive side-loading on the SUS304 rod.
To match this ISO 15552 interchangeable cylinder, specify the 80 mm bore, 475 mm nominal stroke, 10 mm adjustment, PT tapered G3/8 ports, and the SUS304 (B) rod material.
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 SAIJ80BX475-10 FAQ
At 0.9 MPa operating pressure, this 80 mm bore cylinder provides 4523N of push force and 4071N of pull force. It operates efficiently at speeds between 30 and 800 mm/s.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 475 mm nominal stroke down to a 465 mm minimum. This creates a 465-475 mm travel window for end-position tuning without changing the cylinder.
