About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX900-10
The AirTAC SAIJ100X900-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 900 mm travel that can be fine-tuned backward by up to 10 mm, yielding a usable end-position window of 890 to 900 mm. Delivering 3927 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod and PT tapered port threads for robust, high-capacity performance.
This adjustable model omits the FB, CA, CB, and CR mounting options, utilizing a focused set of ISO 15552 interfaces (Basic, FA, LB, TC, FTC, TCM1, TCM2). The rear adjuster acts purely as a mechanical stop to dial in the retract end position during commissioning; it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX900-10 Is Used
Machine Setup Calibration
Dial in the exact 890-900 mm retract position during initial commissioning to perfectly align heavy tooling without machining custom spacer blocks.
Product Changeover
Quickly adapt the end-stop for different product lengths on a high-thrust handling line, shifting the travel limit by up to 10 mm in seconds.
Long-Stroke Assembly Press
Leverage the 3927 N push force and 900 mm travel to drive long-stroke pressing operations, fine-tuning the final clamping position on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX900-10 the Right Cylinder?
Select this 100 mm bore cylinder when an application requires substantial thrust (3927 N push at 0.5 MPa) but demands precise end-position tuning without adding external stops. If your process requires less force, stepping down to an 80 mm bore yields 2513 N push force at 0.5 MPa. Because the 900 mm stroke is long, an external guide is recommended to prevent excessive side-loading on the 25 mm rod.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 900 mm stroke, PT tapered port threads, and the appropriate mounting accessory. Note that the rear adjuster is a travel stop, not a locking mechanism; for load-holding without live air, consider the AirTAC SAIL or BSAI series 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 SAIJ100BX900-10 FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
A rear adjusting screw acts as a mechanical stop, allowing you to shorten the 900 mm nominal stroke by up to 10 mm. This creates an adjustable 890-900 mm travel window for fine-tuning the end position without replacing the cylinder.
