About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX240-100S
The AirTAC SAIJ80X240-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. Because this specific SKU carries a 100mm adjustment code, you can dial the effective travel back from its 240mm nominal length, creating a wide 140-240mm usable stroke window without swapping out the physical actuator.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a magnet (-S) for position sensing with AirTAC CMSE reed or DMSE electronic switches. The extruded aluminum barrel incorporates sensor grooves on both sides, and the rear stopper functions purely as a travel end-limit, not 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 SAIJ80BX240-100S Is Used
Variable End-Stop Positioning
Leverage the 140-240mm travel window to fine-tune retract positions dynamically during machine commissioning or when adapting to new material thicknesses.
Product Size Changeovers
Quickly adjust the stroke by up to 100mm on packaging lines to accommodate different carton sizes without physically replacing the actuator.
Corrosive Environment Actuation
Utilize the SUS304 stainless steel rod for pushing and clamping tasks in washdown or mildly corrosive manufacturing settings where carbon steel would fail.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX240-100S the Right Cylinder?
The 100mm adjustment range is exceptionally useful for machines processing multiple product sizes, allowing operators to set variable end-stops during changeovers rather than installing external stops or buying a fixed-stroke SAI cylinder. To replace an ISO 15552 cylinder, match the 80mm bore, 240mm stroke, PT port threads, and the desired mounting bracket from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Since the nominal stroke is 240mm, the 25mm rod handles moderate side loads, but any lengthy unsupported travel still necessitates an external guide rail to prevent binding. Remember that the rear adjuster and air cushions only decelerate the load; they cannot hold position without live air pressure. For true load-holding, consider an external rod lock or an AirTAC SAIL cylinder.
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 SAIJ80BX240-100S FAQ
At a maximum 1.0MPa pressure, it can deliver up to 513kgf.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke from the 240mm nominal length down to as little as 140mm. This creates a highly versatile 140-240mm travel window for precise end-position tuning without changing the cylinder.
