HK4020

HK4020 The HK4020 is a drawn cup needle roller bearing without an inner ring, designed for applications where the shaft serves as the raceway. This compact bearing features a thin-walled outer ring and small-diameter needle rollers that provide high radial load capacity in minimal radial space. Typical applications include small electric motors, automotive components, power tools, and office equipment where space is limited but high radial load support is required. The bearing requires a hardened and ground shaft surface for proper operation.
