Abstract

An Electrical Discharge Machined (EDM) bearing (120) is provided. The EDM bearing (120) comprises a housing (122) extending around a rotational axis (100X), the housing defining at least one lubricant port (130) connected to an outer circumference of the housing and extending radially to the rotational axis. An EDM flexing pivot pad (128) is machined from the housing (122), the EDM flexing pivot pad configured to provide support to a rotating shaft (110) rotating around the rotational axis (100X) in a first direction. The EDM flexing pivot pad (128) has a lubricant channel (134) aligned with the lubricant port (130). A leading-edge groove (140) is machined on an inner circumference (116) of the EDM flexing pivot pad (128) and in fluid communication with the lubricant channel (134), the leading-edge groove configured to deliver lubricant to the rotating shaft (110). A compressor system including the EDM bearing is also provided.
