    \ud83d\udccb Frequently Asked Questions (FAQ)<\/h3>\n

    <\/p>\n

    \n
    Q1: What is the advantage of the dual-locking (Keyway + Set Screw) design?<\/div>\n
    The standard mechanical keyway handles the bulk of the high-torque transmission and prevents rotational slippage under heavy loads or sudden reversals. The M6 set screw provides axial positioning and extra locking security, ensuring zero-backlash and maximum stability for advanced robotics.<\/div>\n<\/div>\n

    <\/p>\n

    \n
    Q2: Is this flange coupling fully compatible with RoboMaster wheels?<\/div>\n
    Yes. The flange features two different bolt circles. The inner \u00d845mm pitch circle<\/strong> with 3 \u00d7 \u00d85mm through-holes is perfectly spaced and explicitly engineered to match standard RoboMaster 152mm Mecanum wheels.<\/div>\n<\/div>\n

    <\/p>\n

    \n
    Q3: What wheels can be mounted using the \u00d847.5mm bolt circle?<\/div>\n
    The \u00d847.5mm pitch circle<\/strong> (3 \u00d7 \u00d85mm through-holes) is universally compatible with standard 100mm and larger omnidirectional wheels, Mecanum wheels, heavy-duty pneumatic tires, and honeycomb wheels commonly used in ROS research platforms and AGVs.<\/div>\n<\/div>\n

    <\/p>\n

    \n
    Q4: Does the package include the drive key and set screws?<\/div>\n
    Each coupling comes with the corresponding M6 tightening set screw<\/strong> included. Please note that the square drive shaft key (parallel key) is not included and needs to be matched according to your motor shaft’s specifications.<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
