DEVELOPMENT OF GREASE-LUBRICATED TAPERED ROLLER BEARINGS FOR HIGH-SPEED RAIL TRANSPORTATION

An extensive development program has demonstrated that grease-lubricated self-contained tapered roller bearings are suitable for rail applications to speeds of 160 mph. Rubbing lip seals generate excessive heat at speeds above 100 mph and must be replaced with clearance seals. A highly stable soap-thickened grease with extreme pressure additives was found suitable for 200,000 miles of operation without relubrication. Overcharges of lubricant, either initially or at relubrication periods, produce excessive temperature that leads to grease deterioration and a reduced ability to lubricate.
