A wind turbine planet gear shaft has a shaft body with an outer surface, a segment of the outer surface being a slide bearing surface configured to form a radial slide bearing with an inner opening of a planet gear. The slide bearing surface has a first portion configured as a non-load-bearing zone and a second portion configured as a load-bearing zone and exactly one axially elongate oil pocket in the slide bearing surface, that oil pocket being located in the non-load-bearing zone. An oil supply channel in the shaft body has a first end in communication with the oil pocket, and first and second oil return channels in the slide bearing surface each have a first end at a longitudinal end of the oil pocket and a second end open to ambient air.
