The latest addition of the HP-1 coating lowers friction to 1/3 of the original value, thus preventing abrasive wear. Despite there being several systems in place today to prevent engines from experiencing low or no oil pressure, these conditions still do exist. The extreme weight of a crankshaft resting on a non-lubricated bearing can have devastating effects on the life of the bearings. PAI's High Performance Bearings provide a source of much needed lubrication in such conditions. PAI High Performance Bearings
