ABSTRACT:
A portable pressure regulated lubrication system for all bearings derived from using a specially designed thrust bearing. The thrust bearing carries a lubricant from a lubrication fitting on the outside of the thrust bearing to the outer race or races in a bearing hub, which in turn feed the internal bearing rollers or balls and rotating surfaces. The lubricant from the fitting coming in travels without any loss sealed within static seals thus assuring full and positive lubrication of the bearings. The pressure within the system is maintained and protected against excess pressure by a relief fitting with a set rating. The pressure assures improved lubrication and particularly with a grease lubricant improves lubrication and system life, and maintains the system free of voids and contaminants. Seals within the system maintain pressure and prevent lubricant outflow while functioning with static and/or moving parts. Round or square cross-sectioned O-Rings preferably act as seals. A special O-Ring having separable end segments may be used in the systems with the thrust bearings to seal against pressure and lubricant outflow.
