About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX45-30S
The AirTAC SAIJ100X45-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. This model includes a SUS304 stainless steel rod and a built-in magnet for position sensing.
The rear adjuster acts purely as a mechanical stop to set the exact end position, meaning it does not hold the load without live air pressure. For load-holding without continuous air, consider an external rod lock or the SAIL and BSAI series. This cylinder uses a PT G1/2 port and includes adjustable air cushions at both ends to manage deceleration. It is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

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 SAIJ100BX45-30S Is Used
Variable End-Stop Machining
Dial in the exact clamping depth on machining fixtures without machining custom spacers, trimming up to 30 mm off the 45 mm stroke during part changeovers.
Product Size Changeover
Quickly adapt assembly line stops to new product dimensions by adjusting the rear screw, utilizing the 15-45 mm travel window for flexible line setup.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX45-30S the Right Cylinder?
The adjustable stroke is ideal for product changeovers where the exact end-of-stroke varies by up to 30 mm. The integrated magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors for precise positioning feedback.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 45 mm stroke, 30 mm adjustment, PT G1/2 port, and the required mounting subset. The SUS304 stainless steel rod offers superior corrosion resistance compared to standard carbon steel. Because the stroke is short at 45 mm, side-load stress is minimal, but always ensure the load is guided to prevent rod 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 SAIJ100BX45-30S FAQ
The 45 mm nominal stroke can be adjusted backward by up to 30 mm, providing an effective usable travel window of 15 to 45 mm.
No, the rear adjuster functions only as a travel stop to set the end position and does not act as a lock or brake. The cylinder cannot hold a load without live air pressure. For fail-safe load holding, use an external rod lock, a pilot-operated check valve, or AirTAC SAIL and BSAI series cylinders.
