    ● Reinforced welded joint – provides stable torque transfer and higher reliability during continuous operation.

    ● Axial length compensation – absorbs minor misalignment and reduces vibration, protecting connected machinery.

    ● Wide working range – delivers 150–22000 N·m torque and 58–225 mm flange diameter, with flexible shaft lengths tailored to your equipment.

    ● Customizable from 1 piece – one-piece MOQ available, with tailored length and configuration to fit your equipment.

    ● Configurable flange connections – four adapter options: bolt hole, face key, integral face pad, or hirth section, all available for customization.
