About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX500-100S
The AirTAC SAIJ100X500-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 400-500 mm usable travel window, allowing you to dial back the 500 mm nominal stroke by up to 100 mm during commissioning without swapping the barrel or adding external stops.
This variant is equipped with a SUS304 stainless steel rod for corrosion resistance and includes a magnet (-S) for use with CMSE reed and DMSE electronic sensors housed in the dual-side sensor grooves. Fluid supply connects via PT tapered G1/2 ports, and the extruded aluminum barrel integrates adjustable air cushions at both ends to manage deceleration.

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 SAIJ100BX500-100S Is Used
Variable End-Stop Forming
Dial in the exact 400-500 mm travel window during machine setup to accommodate different material thicknesses without mechanical rebuilds.
Product Changeover Diverters
Quickly adjust the retract position on packaging lines when switching box sizes, relying on the 100 mm trim range to set new reject points.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX500-100S the Right Cylinder?
Choose this 100 mm bore when a 63 mm bore (1402 N pull at 0.5 MPa) is insufficient for your tooling payload, but a 125 mm bore is oversized. The 100 mm adjustment window is ideal for product changeovers on automated lines where the exact end-of-stroke position varies by part size. Because the 500 mm stroke is substantial, an external guide rail is strongly recommended to prevent excessive side-loading on the 25 mm rod and M20x1.5 rod thread.
Remember that the rear adjuster is a travel stop, not a locking device; it cannot hold a load without live air pressure. For true fail-safe load holding, select a SAIL pneumatic lock or BSAI clamp-lock cylinder instead. To match this ISO 15552 interchangeable profile, specify: 100 mm bore, 500 mm stroke, 100 mm adjustment, PT G1/2 ports, SUS304 (B) rod, -S magnet, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, 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 SAIJ100BX500-100S FAQ
At the maximum 1.0 MPa pressure, it delivers up to 801 kgf.
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke from 500 mm down to 400 mm. It only sets the travel end and decelerates the load via air cushions; it does not lock the cylinder position without live air.
