The Meritor 31520 is a tapered roller bearing cup designed for use in Meritor differential assemblies. Tapered bearing cups work in matched sets with a tapered bearing cone, together handling both radial and axial thrust loads inside the differential housing. This cup is a genuine Meritor differential component, suited for rebuild and repair work on Meritor-built axle differentials. If you are sourcing parts to overhaul a Meritor differential and need to confirm this cup matches your specific bearing cone or axle model, call Pro Gear and Transmission and we can help verify the correct fit before you order.FeaturesGenuine Meritor part number 31520Tapered roller bearing cup for Meritor differential assembliesDesigned for use with a matched tapered bearing coneHandles combined radial and axial thrust loads in differential housingSuitable for differential rebuild and repair workSold by Pro Gear and Transmission – call to confirm proper fit for your application
