About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-75
The AirTAC SAIJ100X350-75 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 275 to 350 mm, enabling precise end-position tuning at commissioning without adding external stops.
This unit is configured with a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting. The rear adjuster acts purely as a travel stop to set deceleration, meaning it will not hold the load without live air pressure.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 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 SAIJ100 Adjustable Cylinder SAIJ100BX350-75 Is Used
Product Changeover Setup
Dial in the 275-350 mm travel window instantly during format changeovers on packaging lines, avoiding the need to physically swap out cylinders for different carton sizes.
Variable End-Stop Actuation
Implement multiple effective stroke lengths from a single cylinder on automated assembly machines, using the 75 mm adjustment range to accommodate varied part heights.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-75 the Right Cylinder?
The 75 mm adjustment range is ideal for product-size changeovers on a line, letting you dial in the exact 275-350 mm travel without swapping the cylinder. To match this ISO 15552 replacement, specify the 100 mm bore, 350 mm stroke, PT ports, and the SUS304 (B) rod material.
With a 350 mm stroke, the 25 mm rod diameter should be guided externally to prevent excessive side-loading and premature seal wear. Remember that the rear screw adjuster is a stop, not a lock; for load-holding without live air, consider the SAIL or BSAI series. 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 SAIJ100 Adjustable Cylinder SAIJ100BX350-75 FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the effective stroke by up to 75 mm. This creates a usable travel window of 275 to 350 mm, which can be fine-tuned during commissioning without changing the cylinder.
The maximum theoretical push force at 1.0 MPa is 801 kgf.
