Each Mack bearing half has a different stamped number (for Mack internal engineering purposes). The actual part number for both halves sold together is different. Your Mack dealer can supercede the number stamped on either one of the bearing halves, to arrive at the actual part number you can buy.....2 halves in a box. Understand? Those stamped numbers do tell you, the "P1", that you have standard size bearings. Quote Link to comment Share on other sites More sharing options...
