Abstract: A dental handpiece (1) having a drive (3) of a tool (4), which drive is located in a head housing (2), has at least one media-conducting line arranged in the head housing, which media-conducting line has an outlet opening to the tool, and a tool receptacle (16) arranged in a drive chamber, which tool receptacle is rotatably supported by means of a rolling bearing (11) in a support (14) of the head housing (2) on a side of the drive chamber facing the tool. The rolling bearing has an outer race (13), which is supported against the head housing (2) radially in the support (14) in the area of a raceway (22) and which has a sub-area (21), the outside diameter D2 of which is reduced compared to the outside diameter D1 in the area of the raceway (22). The head housing has a housing projection (23), which extends into the area of the reduced outside diameter D2, and the media-conducting line (17) runs at least partially through said housing projection (23).

Abstract: An object is to provide a motor-incorporation-spindle ball bearing capable of allowing cooling air which enters inside the bearing of the motor-incorporation-spindle to be discharged smoothly out of the bearing without causing turbulent flow inside the bearing, does not cause a retainer easily to be vibrated, and provides a high level of silent operation. A seal plate has a length to allow air to pass through the bearing from an entrance side toward an exit side substantially straightly without resistance. Therefore, the seal plate is less likely to be exposed to unnecessary force when the air passes through the bearing; the seal plate is prevented from wobble and deformation; stable sealing is ensured; the air is discharged smoothly without causing turbulent flow inside the bearing; a retainer is not easily vibrated, and silent operation is maintained.
