About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX300-40
The AirTAC SAIJ100X300-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end-of-travel position. It provides a usable stroke window of 260 to 300 mm, enabling precise positioning changes during commissioning or product changeovers without adding external stops.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches.

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 SAIJ100BX300-40 Is Used
Variable End-Stop Positioning
Dial in the exact 260-300mm retraction point during machine setup to accommodate different material thicknesses without swapping out the entire actuator.
Product Changeover Diverter
Quickly adjust the stroke by up to 40mm on a packaging line to handle varying box sizes on the fly, ensuring precise diverting forces.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX300-40 the Right Cylinder?
The adjustable 260-300mm travel window is ideal for machines requiring variable end-stops between product sizes. When specifying your replacement, match the 100mm bore, 300mm nominal stroke, 40mm adjustment, PT port thread, SUS304 (B) rod material, and standard mounting (no -S magnet). Because the stroke is 300mm, an external guide is recommended to prevent rod side-loading and premature wear. Remember that the rear adjuster acts only as a travel stop; for load-holding without live air pressure, select an AirTAC SAIL or BSAI cylinder. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.
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 SAIJ100BX300-40 FAQ
A rear external adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke from its 300mm nominal length by up to 40mm. This provides a usable travel window of 260-300mm. The adjuster only sets the travel end and does not lock or hold the load without continuous air pressure.
