About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-50
The AirTAC SAIJ80X260-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 260 mm stroke that can be fine-tuned backward by up to 50 mm, yielding a usable travel window of 210-260 mm. The extruded aluminum barrel includes sensor grooves on both sides for straightforward switch integration.
This unit is configured with a SUS304 stainless steel piston rod for superior corrosion resistance and uses PT tapered port threads with a G3/8 connection. The 25 mm rod and M20x1.5 thread provide a robust interface that handles side loads well, though the 260 mm length still benefits from an external guide. The rear stopper allows precise end-position tuning during commissioning without adding external stops, acting purely as a travel limit rather than a load-holding lock.

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 SAIJ80BX260-50 Is Used
Product Changeovers
Dial in the 210-260 mm retract distance on the fly when switching between product sizes on a packaging line, avoiding mechanical rebuilds.
Machine Setup
Fine-tune the end-of-stroke position during commissioning to achieve precise mechanical alignment without adding external stopper blocks.
Corrosive Environments
Leverage the SUS304 stainless steel rod for pushing and pulling tasks in washdown or mildly corrosive industrial settings.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-50 the Right Cylinder?
The adjustable 210-260 mm window is ideal for product changeovers on a line, letting you dial in the exact retract distance without swapping the cylinder. For an exact ISO 15552 replacement, match the 80 mm bore, 260 mm stroke, 50 mm adjustment, PT G3/8 port, and standard mounting.
Because the stroke is 260 mm, ensure an external guide supports the load to prevent excessive rod bending. Remember that the rear adjuster and air cushions only set the travel end and decelerate the load; they do not hold position without live air. For load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80BX260-50 FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw acts as a stopper that lets you shorten the effective stroke from its nominal 260 mm down to 210 mm. It only sets the travel end and does not lock the load without continuous air pressure.
