摘要
The invention relates to a motor-driven machine tool unit such as a multi-axis rotary head, a motor spindle, a rotary table, or the like, comprising a rolling bearing (3), which is designed in the form of a floating bearing (3) in particular. The rolling bearing (3) has multiple rolling elements (6), in particular rollers (6), cylinders, or needles, which rotate about a common rotational axis (2); a first rolling bearing element (5), in particular an outer ring (5), which is arranged on the outside of the rolling elements (6) in a radial direction; and a second rolling bearing element (4), in particular an inner ring (4), which is arranged on the inside of the rolling elements (6) in the radial direction, wherein at least one of the rolling bearing elements (4, 5) comprises at least one lubricant channel for conducting lubricant. According to the invention, a more efficient lubrication is carried out and the increasing requirements of modern machine tools or machine tool units are better met. This is achieved in that the lubricant channel is designed as a discharge channel (9, 10) for discharging lubricant, the flow direction (14) of the lubricant being oriented away from the rolling elements (6) in the discharge channel (9, 10).
