About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX20-10
The AirTAC SAIJ32X20-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position. With a 20mm nominal stroke and a 10mm adjustment range, it provides a usable travel window of 10-20mm. This adjustment is ideal for dialing in exact sensor or clamping locations during machine commissioning without adding external stops. In the 32mm bore class, it delivers 402N of push force and 345N of pull force at 0.5MPa.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threading. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. Note that the rear adjuster acts strictly as a mechanical stop for deceleration and positioning; it does not hold the load without continuous air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX20-10 Is Used
Sensor Calibration
Dial in the exact 10-20mm travel distance during machine commissioning to trigger proximity sensors perfectly without remachining hard stops.
Light Clamping
Apply 402N of precise clamping force to delicate workpieces, adjusting the final position by up to 10mm to accommodate varying part tolerances.
Product Changeover
Quickly adapt a packaging or assembly station for a new product size by turning the rear stopper screw rather than swapping the entire cylinder.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX20-10 the Right Cylinder?
Choose this 32mm bore model when your application requires 402N push force at 0.5MPa and highly precise, short-stroke positioning. The 10mm adjustment window is perfect for product changeovers where end-of-stroke positions vary slightly. If your process demands more clamping force, stepping up to the 40mm bore yields 628N of push force at 0.5MPa. Conversely, if your force requirements are lower, a smaller bore might be more efficient.
Because the SAIJ32X20-10 is dimensionally interchangeable per ISO 15552, it replaces any equivalent ISO 15552 cylinder with matching 32mm bore, 20mm stroke, PT port, and basic mounting dimensions. For load-holding without live air pressure, this standard cylinder is insufficient; you should consider the SAIL (air-released lock) or BSAI (clamp-lock) variants instead. This model omits the FB, CA, CB, and CR mounting styles, offering a focused set of mounts: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ32BX20-10 FAQ
At a 0.5MPa operating pressure, this 32mm bore cylinder generates 402N of push force and 345N of pull force. It can reach up to 724N of push force at 0.9MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 20mm down to 10mm. This creates a 10-20mm usable travel window for fine-tuning end positions without replacing the cylinder.
