About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX300-100S
The AirTAC SAIJ80X300-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated -S magnet enables precise position detection using AirTAC CMSE reed or DMSE solid-state sensors. Built with a SUS304 stainless steel rod and PT tapered ports, it handles demanding environments.
This model provides a 200-300mm usable travel window, allowing you to dial back the nominal 300mm stroke by up to 100mm. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning. It is not a locking mechanism, so you must maintain live air to hold a load. For applications requiring true load-holding without pressure, consider an external rod lock or the AirTAC BSAI clamp-lock series.

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 SAIJ80BX300-100S Is Used
Machine Setup & Changeover
Dial in the exact retract distance from 200 to 300mm during product line changeovers without replacing the cylinder or adding external mechanical stops.
Variable End-Stop Positioning
Provides an adjustable physical stop for diverter arms or pushers on conveyors, allowing operators to fine-tune the stroke end-position on the fly.
Assembly Line Calibration
Offers a 100mm travel window to perfectly tune press fits or clamping positions during initial equipment commissioning and fixture setup.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX300-100S the Right Cylinder?
The 100mm adjustment range is perfect for product-size changeovers on a line, eliminating the need to physically swap cylinders or bolt on external stops.
Because this unit features a 300mm stroke, the 25mm rod diameter should be paired with an external guide to prevent excessive side-loading on long unsupported travels. This SAIJ variant uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552 standards, featuring a PT port thread and an -S magnet for CMSE/DMSE sensors.
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 SAIJ80BX300-100S FAQ
The rear adjuster screw lets you shorten the effective stroke from its nominal 300mm down to 200mm, creating a 200-300mm travel window. This stopper only sets the end position and deceleration; it does not lock the load without live air pressure.
