Timken U399U360L — Tapered Roller Bearing
Overview
Tapered roller bearing Timken U399U360L carries combined radial and thrust loads in automotive drivetrain assemblies, final drives, and wheel hubs. Bore diameter measures 39.688 mm, outer diameter is 73.025 mm, and total assembly width is 22.100 mm. Manufactured from case-hardened high-grade alloy steel, this assembly features a U399 inner cone with stamped steel cage and rollers, alongside a separable U360L outer cup. Precision-ground raceways lower operating friction, vibration, and operating heat under severe load conditions. The engineered tapered geometry distributes contact stress uniformly along the roller profiles, preventing localized stress concentrations and shaft deflection during operation.
This bearing assembly fits drive axle differentials, transfer cases, gearbox input shafts, and heavy-duty wheel hubs on commercial vehicles, pick-up trucks, off-road vehicles, and industrial machinery. Replacement is required when detecting persistent droning noise, wheel hub end-play, driveline vibration, or elevated temperature around the axle housing. Water contamination, loss of grease lubrication, and surface fatigue spalling create pitting on the inner and outer raceways, leading to rough rotation. Fitting a replacement Timken U399U360L bearing restores correct shaft preload, eliminates axial play, and protects internal differential gears from severe gear teeth misalignment.
