    摘要: A dental handpiece has a rotor assembly (10) with a rotor (15a) and two ball bearing assemblies (13, 14) supporting a rotor (15a). At least one of the ball bearing assemblies (13, 14) has a ball (20) and a retainer (21). The retainer (21) has at least one grease retaining groove (30, 50) or void (51) therein.

    摘要: Improvements in material-to-material connections are provided. For example, metal-to-metal connections are improved, such as the interface connection between a dental handpiece bur tube (10) and a component such as a bearing (12). At least one marking, such as a laser marking (20) is provided such that an amount of excavate material (21) is excavated from the marking (20). When a component such as a bearing (12) is positioned upon the bur tube (10), a portion of the excavate material (21) is physically impinged between the two components (10, 12) filling any spaces or gaps therebetween.
