Product Introduction
The 104949/104911 is a widely specified inch-series tapered roller bearing engineered around a standard 50.8 mm (2-inch) inner bore. Sized precisely at 50.8 x 82.55 x 21.59 mm, this cup and cone set provides high load density and structural rigidity under intense combined radial and axial dynamic stresses. Forged from vacuum-degassed GCr15 high-carbon chromium steel, it undergoes state-of-the-art heat treatment to resist raceway fatigue and surface wear. It is a fundamental replacement component for global B2B clients operating in light commercial automotive, trailer axle, and power transmission markets.
Applications
Commercial truck and utility trailer wheel hubs.
Automotive differentials and transfer cases.
Agricultural gearboxes and industrial drive shafts.
