This transmission bearing is a replacement sold individually and fits Mack transmission platforms, along with equivalent applications from Caterpillar, Navistar, Kenworth, Dana, and GMC Truck. It supports smooth shaft rotation under load within the transmission housing, helping cut friction between moving components. Being sold as a single unit, it can be swapped in without ordering a matched set.Interchanges:Caterpillar 1T0441Dana 550594GMC Truck 954295Kenworth K1594Mack 25096423Mack 46AX533Navistar 921822C1GBG-7322FeaturesTransmission bearingTech SpecsSell pack: 1 EachProduct group: TransmissionUsed in these Mack modelsCRD 150 DifferentialCRDPC 92 / CRDPC 112 Differential
