Airtac SAIJ100 Adjustable Cylinder SAIJ100BX900-10S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100BX900-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 900mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX900-10S
The AirTAC SAIJ100X900-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 3927N of push force at 0.5MPa and features a 900mm stroke that can be fine-tuned down by 10mm, providing a usable travel window of 890-900mm. This adjuster acts purely as a travel stop to set deceleration, not as a lock to hold loads without live air. Built with a SUS304 stainless steel rod and a PT tapered port thread, it is designed for demanding environments.
This model includes a magnet for CMSE and DMSE sensors, which mount cleanly into the extruded aluminum barrel's dual sensor grooves. The generous 900mm stroke requires careful external guiding to prevent excessive side-loading on the 25mm rod. It uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX900-10S Is Used
Machine Changeover
Dial in the 890-900mm end stop during product size changes without physically swapping out the entire actuator.
End-Position Tuning
Fine-tune the retract position at commissioning to hit exact indexing marks using the 10mm rear adjustment screw.
Long-Stroke Assembly
Drive heavy 3927N push loads over a 900mm travel distance while keeping the ISO 15552 mounting interface standard.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX900-10S the Right Cylinder?
Choose this 100mm bore when an 80mm bore (2513N push at 0.5MPa) is insufficient but a 125mm bore (6136N push) would be overkill. The adjustable stroke is ideal for machine setup and product changeover, letting you dial in the exact end position without swapping cylinders or adding external stops. To replace an ISO 15552 cylinder, match the 100mm bore, 900mm stroke, 10mm adjustment, PT G1/2 port, mounting style, and the -S magnet requirement.
Because the 900mm stroke creates a long lever arm, you must use an external guide to support the load and protect the rod from side-load wear. Remember that the rear screw stopper and the variable air cushions only manage travel ends; for true load-holding without live air pressure, select an AirTAC SAIL or BSAI cylinder 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 SAIJ100BX900-10S FAQ
At a 0.5MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7MPa, the push force increases to 5497N.
The rear adjuster screw lets you shorten the 900mm nominal stroke by up to 10mm, creating an 890-900mm usable travel window. This stopper only sets the travel end and deceleration; it does not lock or hold the load without live air pressure.
