Abstract
A 'pancake-like' thrust bearing arrangement with gravity-fed lubrication is angular to a horizontal plane and has a top edge above such plane. A load-support structure oscillates on the bearing. Such bearing has a lubricant feed aperture at the top edge and plural lubrication grooves formed in the flat bearing face and connected to such aperture by feed passages. The grooves are oriented so that they 'run downhill,' i.e., so that they intersect a circle concentric with the bearing center. Grease moves by gravity along the grooves which are 'closed-ended' to help prevent premature expulsion of grease from the bearing face.
