OTR Wheel Bearing Kit SET413 HM212049/HM212011 Cup & Cone. This matched cup-and-cone bearing kit is engineered to restore wheel-end geometry and rolling performance for heavy-duty truck and trailer axles that use the HM212049 cone and HM212011 cup combination. The kit contains a tapered roller cone and a corresponding cup manufactured to the same dimensional envelope as widely used OEM sets: bore diameter 2.625", cup outside diameter 4.8125" and set width 1.500" (66.675 mm × 122.238 mm × 38.1 mm). Those dimensional references make the kit suitable for direct replacement where SET413 family bearings are specified. In operation, worn or failed wheel bearings are a primary cause of increased rolling resistance, elevated hub temperatures, uneven wear on seals and races, and unpredictable roadside failures. Replacing the full matched set addresses preload and roller alignment simultaneously, eliminating the need to pair used cones with new cups and ensuring expected life and predictable re-torque intervals. For fleet maintenance programs, using a matched bearing kit reduces vehicle off-road time by restoring designed bearing preload and heat dissipation characteristics in a single service event. The kit supports standard service procedures for inspection, cleanup, repacking or resealing of hub assemblies and returns the wheel end to repeatable measurement points used for endplay and torque specifications. Because the cones and cups are supplied as a matched pair, shops save time on parts selection and avoid delays caused by sourcing individual components. The product is presented as a direct-replacement wheel bearing kit for fleet and service center inventories where SET413 cross-references apply, enabling faster turnarounds and consistent parts stocking for known axle types.
