Abstract
A ring spindle assembly and process for re-lubricating a ring spindle having a vertically arranged bearing housing with a closed bottom. A step bearing is arranged in an oil-bath of the bearing housing for a rotating shaft. In the bearing housing, at least two lubricating channels are provided above the desired oil level of the oil-bath. When the shaft remains in the bearing housing, oil is filled into one lubricating channel until oil comes out of the other lubricating channel. A certain amount of oil is subsequently sucked out through the lubricating channel, so that the oil reaches the desired level.
