The planetary transmission further includes a pilot bearing, and a double-walled pipe received in the pilot bearing and having a central portion designed to have an outlet point for dispensing lubricant into the transmission component. A bushing is disposed in a region of the outlet point such that a gap is formed between the bushing and the transmission component.
