About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX155-30
The AirTAC SAIJ80X155-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 125 to 155 mm, allowing you to dial in the exact retract end-position during commissioning without adding external stops.
This specific configuration uses a SUS304 stainless steel piston rod for superior corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible mounting of CMSE reed or DMSE solid-state switches. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR styles.

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 SAIJ80BX155-30 Is Used
Machine Setup Calibration
Dial in the exact 125 to 155 mm travel window during initial commissioning to perfect the end-position without swapping cylinders or adding external stopper blocks.
Product Changeover
Quickly adjust the retract stop on packaging lines when handling slightly different carton sizes, using the 30 mm trim range to adapt the stroke on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX155-30 the Right Cylinder?
The 30 mm adjustment range is ideal for product changeovers where the exact end-of-stroke varies slightly, replacing the need to swap out a fixed-stroke SAI cylinder. Remember that the rear adjuster acts only as a mechanical stop to decelerate the travel end and does not hold the load without live air pressure. For load-holding requirements, consider an AirTAC SAIL or BSAI cylinder. To match this ISO 15552 replacement exactly, specify the 80 mm bore, 155 mm stroke, 30 mm adjustment, PT G3/8 port, and your required mounting style.
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 SAIJ80BX155-30 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 30 mm from the 155 mm nominal length, creating a 125 to 155 mm travel window. It acts as a mechanical stop to tune the end-position and is not a lock, meaning the cylinder will not hold a load without continuous air pressure.
