About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX55-30
The AirTAC SAIJ100X55-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 55 mm nominal stroke by up to 30 mm. This creates a highly flexible 25-55 mm usable travel window, perfect for fine-tuning end positions at commissioning without swapping the cylinder or adding external stops.
This specific SKU features a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsh environments. It uses PT tapered port threads and lacks a magnet, meaning position sensing is handled externally rather than with internal CMSE or DMSE switches. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock, so live air pressure is required to hold the load.

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 SAIJ100BX55-30 Is Used
Variable End-Stop Forming
Dial in the exact 25-55 mm travel distance for pressing or forming different material thicknesses without changing out the cylinder.
Machine Setup Commissioning
Fine-tune the retract position during initial machine build to perfectly align tooling, absorbing mechanical tolerances on the fly.
Product Size Changeover
Quickly adjust the stroke stop when a production line switches to a new product size, minimizing downtime for mechanical reconfiguration.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX55-30 the Right Cylinder?
The SAIJ is chosen over a fixed SAI cylinder when product sizes change on a line and the exact end-of-stroke needs on-the-fly mechanical tuning. For exact ISO 15552 interchangeability, match the 100 mm bore, 55 mm stroke, 30 mm adjustment, PT port threads, and no-magnet configuration. Note that the rear adjuster and air cushions only manage travel ends; for true load-holding without live air, select an AirTAC SAIL or BSAI cylinder instead.
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 SAIJ100BX55-30 FAQ
The rear adjuster screw lets you mechanically shorten the 55 mm nominal stroke by up to 30 mm, providing a usable travel window of 25-55 mm. It acts as a physical stop to tune the end position without needing external stops.
At the maximum 1.0 MPa pressure, the push force reaches 801 kgf.
