- Genuine Husqvarna Part — sourced directly from Husqvarna's OEM supply chain, so you receive the same component installed at the factory.
A spacer is a precision-machined component that maintains a fixed gap or positional relationship between two adjacent parts within an assembly. In a core drill motor, spacers ensure that rotating and stationary components are held at the correct axial or radial distance, preventing metal-to-metal contact, uneven bearing loads, and vibration that can accelerate wear. When a spacer is damaged, deformed, or missing, surrounding components can shift out of alignment, leading to increased stress on bearings, shafts, and housings — and ultimately compromising the accuracy and reliability of the drill.
