A coupler serves as the mechanical link between two rotating or hydraulic components, transmitting power or fluid drive from one assembly to the next. When a coupler wears, cracks, or fails, the connection between those components is compromised — resulting in lost output, vibration, or complete disengagement of the drive system. On demolition robots and power packs like those in the DXR and PP325E families, maintaining a sound coupling interface is essential for consistent hydraulic and mechanical performance across demanding job conditions.
