807049/807010 Tapered Roller Bearing 53.975x104.775x36.513mm

Extra-Wide Contact Profile: The 36.513mm width permits larger rollers to distribute extreme radial and thrust loads safely.
Impact Resilience: Formulated to absorb severe shock loads common in off-highway and heavy transport applications.
Micro-Honed Raceways: Super-finished contact zones reduce operational friction, keeping operating temperatures low under continuous torque.
Exact ABMA Compliance: Manufactured to strict imperial tolerance standards for universal global replacement fitment.

Product Introduction

The 807049/807010 is an exceptionally robust inch-series tapered roller bearing engineered for severe-duty applications requiring maximum radial support and heavy axial thrust capacity. With a 53.975 mm (2.125 in) inner bore, 104.775 mm (4.125 in) outer diameter, and a wide 36.513 mm (1.4375 in) profile, this set (Cone: 807049, Cup: 807010) accommodates oversized rolling elements to handle intense operational torque. Built from vacuum-degassed GCr15 chromium steel, it delivers high fatigue resistance and structural rigidity, making it a critical component for heavy commercial truck differentials, drive axles, and industrial gear units.

Applications

Heavy commercial vehicle differential pinions and rear axle assemblies.
Off-highway mining trucks, construction machinery, and planetary drives.
Industrial heavy reduction gearboxes and winches.
