This differential bearing cup measures 5.5 inches in outer diameter and 1 inch in width, fitting differential carriers across Mack, Volvo, Navistar, Caterpillar, Kenworth, GMC, and Dana axle applications. Made by PAI, it pairs with its mating cone to form the outer race that lets the pinion or side bearing rotate smoothly under axle and gear loads. Matching the cup and cone correctly helps maintain proper bearing preload.
