About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX50-50
The AirTAC SAIJ100X50-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 50 mm nominal travel to anywhere in a 0-50 mm usable window.
This configuration features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic switches if a magnet is added later.

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 SAIJ100BX50-50 Is Used
Product Changeovers
Dial in the exact end-of-stroke position for varying part sizes on a packaging line using the 0-50 mm rear adjustment screw.
Variable End Stops
Replace fixed mechanical stops with this adjustable cylinder to quickly reconfigure actuation depth without adding external hardware.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX50-50 the Right Cylinder?
The 50 mm adjustment range is ideal for product-size changeovers, letting you fine-tune the end position without swapping hardware. The rear screw acts purely as a travel stop for deceleration; it does not hold the load without live air, so use a SAIL or BSAI lock cylinder for pneumatic load-holding.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 50 mm stroke, PT ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the nominal stroke is short, side-loading is minimal, but always ensure the M20x1.5 rod thread is aligned to avoid binding.
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 SAIJ100BX50-50 FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster allows you to shorten the effective travel by up to 50 mm. Since the nominal stroke is 50 mm, you can set the usable travel anywhere in a 0-50 mm window to perfectly tune the end position.
