It consists of a cone (inner race with rollers, part number 47679) and a cup (outer race, part number 47620). This set is typically used as the outer wheel bearing on the rear axle of Mack heavy-duty trucks, and it fits many other commercial truck wheel ends that require a bearing with a 3.000-inch bore and 5.250-inch outer diameter. Bearings are replaced when they show signs of wear, pitting, or noise to prevent wheel end failure and ensure safe operation.
