Timken JM511945 & 3920 Tapered Roller Bearing Set – High-Performance Cone & Cup Assembly for Axle, Hub, and Transmission Applications
The Timken JM511945 & 3920 is a matched tapered roller bearing set consisting of the JM511945 bearing cone and the 3920 bearing cup. With a 2.5591-inch inner diameter and 4.4375-inch outer diameter, this set is engineered to support heavy radial and axial loads in axle hubs, differentials, and powertrain components.
Designed for high-performance applications, this Timken set ensures optimal roller alignment, smooth operation, and extended bearing life. The tapered roller design promotes efficient load distribution and reliable performance under high-speed and high-load conditions.
Manufactured from premium-grade alloy steel, both the cone and cup are heat-treated and precision-ground to maximize durability, minimize wear, and resist heat and deformation in harsh operating environments.
This OEM-quality bearing set is ideal for use in heavy-duty trucks, trailers, off-road equipment, and other demanding industrial applications where long-term reliability is essential.
