A Hub used in hydraulic pump coupling is responsible for connecting the pump's input shaft to the power source. The hub has a cylindrical shape with a central bore that matches the diameter of the pump's input shaft. The bore may have a keyway or other features to ensure a secure fit with the shaft.

Attributes:
• Reducing wear and tear on the pump and other components
• Ensures precise alignment between the power source and the hydraulic pump

Applications:
A Hub used in hydraulic pump coupling prevents unexpected disengagement or separation between the power source and the pump, enhancing the safety of the hydraulic system.
