About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-75
The AirTAC SAIJ32X650-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 650 mm travel by up to 75 mm for a precise 575 to 650 mm usable window. It delivers 402 N of push force at 0.5 MPa, utilizing a PT tapered port and a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance.
Because the stroke is 650 mm on a 32 mm bore, the 12 mm rod and M10x1.25 thread require careful alignment; an external guide is strongly recommended to prevent excessive side loading on the long unsupported travel. The rear adjuster acts purely as a travel stop to fine-tune the end position during commissioning without swapping cylinders, and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-75 Is Used
Machine Changeover
Quickly fine-tune the 575-650 mm retract end-stop during product size changeovers without physically swapping out the entire cylinder.
Variable End Stops
Ideal for diverter gates on long conveyors where the exact 650 mm stroke position needs minor 75 mm rear adjustments at commissioning.
Long-Reach Positioning
Handles long-trroke pushing tasks using its 402 N force at 0.5 MPa, relying on external guides to support the extended 12 mm rod.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-75 the Right Cylinder?
Choose this 32 mm bore when an application requires a long reach with the flexibility to adjust the retract end-stop on the fly. If you need higher thrust, stepping up to the 40 mm bore increases push force to 628 N at 0.5 MPa, but this SAIJ32X650-75 provides a compact ISO 15552 footprint with a 575-650 mm adjustable travel window. The PT port thread and SUS420J2 rod material are fixed configurations for this specific SKU.
For any stroke of 650 mm, managing side load is critical; ensure external guides support the load to protect the piston rod. Remember that the rear adjuster is a stop, not a lock, so if the machine loses air pressure, the cylinder will not hold its position. For load-holding requirements without live pressure, consider an AirTAC SAIL or BSAI cylinder instead. Mounting options are limited to 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 SAIJ32AX650-75 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm, creating a usable travel window between 575 mm and 650 mm. This lets you fine-tune the end position at commissioning without adding external stops.
At a standard operating pressure of 0.5 MPa, the SAIJ32X650-75 provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
