Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-75
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 900mm stroke, G1/8 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 Adjustable Cylinder SAIJ32 SAIJ32BX900-75
The AirTAC SAIJ32X900-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 900 mm nominal stroke that can be dialed back by up to 75 mm, yielding an effective 825-900 mm travel window for precise end-position tuning during commissioning. The extruded aluminum barrel includes sensor grooves on both sides, though this specific configuration omits the magnet, meaning electronic position sensing is not supported out of the box.
Configured with a SUS304 stainless steel rod (code B) and PT tapered port threads, this 32 mm bore unit delivers 402 N of push force at 0.5 MPa. The 12 mm rod and M10x1.25 thread provide a compact interface, but at 900 mm of travel, the unsupported length is substantial. The rear adjuster acts strictly as a travel stop to set deceleration and end limits, not as a lock to hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-75 Is Used
Machine Changeover
Dial in the exact end-stop from 825 to 900 mm during product size changes on a packaging line without replacing the cylinder.
Long-Stroke Assembly
Use the 900 mm travel for extended reach operations, fine-tuning the final position to account for mechanical tolerances.
Sensor Groove Integration
Leverage the dual-side sensor grooves for future upgrades, though this specific B-rod configuration ships without a magnet.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-75 the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your application requires exact end-position tuning without swapping physical components or adding external stops. If your process demands higher thrust, stepping up to the 40 mm bore increases push force to 628 N at 0.5 MPa. Because the 900 mm stroke is long, an external guide is highly recommended to manage side loads and prevent rod binding, as the 12 mm rod cannot support heavy lateral forces alone.
This model matches the ISO 15552 mounting interface dimensions and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits FB, CA, CB, and CR options. If your setup requires true load holding without continuous air pressure, consider the SAIL or BSAI series, as the SAIJ rear adjuster and air cushions only regulate travel endpoints. Speed ranges from 30-800 mm/s.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32BX900-75 FAQ
The 32 mm bore generates 402 N of push force and 345 N of pull force at 0.5 MPa. At the maximum operating pressure of 1.0 MPa, it delivers up to 82 kgf.
A rear adjuster screw shortens the effective stroke by up to 75 mm, creating a usable travel window of 825-900 mm. It functions as a mechanical stop to fine-tune end positions and does not lock the load.
