About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX900-30
The AirTAC SAIJ100X900-30 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 900 mm nominal stroke that can be fine-tuned down by up to 30 mm, providing an exact 870-900 mm usable travel window.
This unit is configured with a SUS304 stainless steel rod (code B) for superior corrosion resistance and ships with PT tapered port threads. Because it lacks the -S magnet option, it operates without position sensing. The rear adjuster functions strictly as a mechanical stop to dial in the retract end position during commissioning; it does not lock or hold the load without continuous live air pressure.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ100BX900-30 Is Used
Product Changeover
Dial in the 870-900 mm travel window during format size changes on a packaging line without physically replacing the actuator.
Commissioning Calibration
Trim the retract stroke by up to 30 mm during machine setup to perfectly align tooling without adding external mechanical stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX900-30 the Right Cylinder?
The adjustable 870-900 mm window is ideal for applications requiring precise end-position tuning during product changeovers, eliminating the need to swap out a fixed-stroke SAI cylinder or bolt on external stops. To match this ISO 15552 footprint for a direct replacement, verify the 900 mm stroke, 30 mm adjustment range, PT port, and mounting style.
With a 900 mm stroke, the 25 mm diameter rod and M20x1.5 thread provide substantial rigidity, but an external guide is highly recommended to prevent excessive side-loading on the unsupported piston. Remember that the rear adjuster only sets the travel end and relies on the air cushion for deceleration; for true load-holding without live air, select a SAIL pneumatic lock or BSAI clamp-lock cylinder instead. Mounting options are limited to 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 SAIJ100BX900-30 FAQ
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the 900 mm nominal stroke by up to 30 mm. This creates an 870-900 mm adjustable travel window for fine-tuning the end position at commissioning, though it does not lock the load without live air.
