About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX45-10S
The AirTAC SAIJ100X45-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 35 to 45 mm, allowing you to dial back the 45 mm nominal stroke by up to 10 mm during commissioning without adding external stops.
This unit is configured with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel utilizes PT tapered ports (G1/2), and the adjustable rear stopper acts purely as a travel end-deceleration device, not a load-holding lock.

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 SAIJ100BX45-10S Is Used
Machine Changeover
Fine-tune the 35-45 mm end position during product size transitions without swapping cylinders or adding physical shims.
Variable End-Stop Setup
Dial in the exact retract distance at commissioning using the rear screw, perfect for delicate pressing or clamping tasks.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX45-10S the Right Cylinder?
The adjustable stroke is ideal for applications requiring variable end-stops or fine position tuning during machine changeover, whereas a fixed SAI cylinder locks you into a single dimension.
For direct replacements, match the 100 mm bore, 45 mm stroke, 10 mm adjustment, PT port thread, and the -S magnet option. Because the stroke is under 300 mm, side-load stress is minimal, but always guide external loads. If you need to hold a load without live air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster cannot lock the position.
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 SAIJ100BX45-10S FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw lets you shorten the 45 mm nominal stroke by up to 10 mm, creating a 35 to 45 mm usable travel window. This stopper only sets the end position; it does not hold the load without live air.
