About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX900-75
The AirTAC SAIJ100X900-75 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 825 to 900 mm usable travel window, allowing you to dial back the stroke by up to 75 mm during commissioning without adding external stops. The rod is constructed from SUS304 stainless steel, and the PT tapered port threads seal securely against system pressure.
This 100 mm bore unit omits the FB, CA, CB, and CR mounts, retaining the standard Basic, FA, LB, TC, FTC, TCM1, and TCM2 interface subset. The rear adjuster acts strictly as a travel stop to set deceleration endpoints, not as a lock. For load-holding without live air pressure, a SAIL or BSAI cylinder is required. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches.

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 SAIJ100BX900-75 Is Used
Variable End-Stop Machining
Fine-tune the 825-900 mm travel window during machine setup to accommodate different part lengths without physically swapping the actuator.
Product Changeover Diverter
Adjust the rear stopper on the fly when a packaging line switches to a new box size, ensuring precise positioning for heavier loads.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX900-75 the Right Cylinder?
The adjustable 825-900 mm window is ideal for product changeovers where exact end positions vary slightly. Because the stroke is 900 mm, the 25 mm rod and M20x1.5 thread face significant leverage; an external guide is strongly recommended to prevent side-load damage.
To match this ISO 15552 footprint for a replacement, verify the 100 mm bore, 900 mm stroke, 75 mm adjustment range, PT port threads, SUS304 rod material, and the specific mounting accessory. Remember that the rear adjuster only trims the travel distance and does not hold the load pneumatically.
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 SAIJ100BX900-75 FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw lets you mechanically shorten the effective travel from the 900 mm nominal stroke down to 825 mm. This stopper only sets the end position and deceleration; it does not lock the load without continuous air pressure.
