A plastic cage consists of two side rings that have a common axis of rotation and are axially spaced apart from one another, and a plurality of cage webs that connect the side rings to one another and between which pockets are formed for receiving rolling elements, wherein the plastic cage is axially slotted at at least one peripheral location by a parting line which defines a first cage end and a second cage end and at the boundary surfaces of which mutually corresponding closure elements are located, by means of which the first and second cage ends can be fixed relative to one another both in the axial and radial direction and in the peripheral direction.

A planetary gearbox includes a shaft, a planetary carrier, first and second planetary pins arranged on the planetary carrier, first and second planetary gears mounted on the planetary pins via respective bearings, and a lubricant collecting tray. The shaft has a shaft channel for radially conducting a lubricant to an outer face of the shaft and the planetary pins have respective pin channels for conducting the lubricant to the respective bearings. The lubricant-collecting tray has a collection space for collecting the lubricant supplied via the shaft channel and hollow feed ports that open into respective pin channels. The hollow feed port closest to the shaft channel, when viewed in a circumferential direction, has an opening cross-section that is less than an opening cross-section of the other hollow feed port.
