About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX135-40
The AirTAC SAIJ80X135-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel anywhere within a 95 to 135 mm window.
This specific configuration incorporates a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting, and the mounting hardware covers a specific subset including 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 SAIJ80BX135-40 Is Used
Variable End-Stop Tuning
Dial in precise retract distances between 95 and 135 mm during machine commissioning to accommodate different material thicknesses without mechanical rework.
Product Size Changeovers
Quickly adjust the stroke window on packaging lines to handle varying package dimensions, reducing downtime between production runs.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX135-40 the Right Cylinder?
The 40 mm adjustment range is ideal for product changeovers, letting you dial in the exact end position without swapping cylinders or adding external stops. Remember that the rear adjuster functions strictly as a travel stop, not a lock; the SAIJ cannot hold a load without live air pressure. For load-holding requirements, consider an external rod lock or the AirTAC SAIL series. Since the nominal stroke is 135 mm, side-load risks are minimal, but external guides should still be used if operating under heavy lateral stress.
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 SAIJ80BX135-40 FAQ
At the maximum pressure of 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke from its nominal 135 mm down to 95 mm. This provides a 40 mm tuning window to set precise end positions during setup without needing a different cylinder.
