The TIMKEN 47620 (Cone) and 47686 (Cup) set constitutes a single-row Tapered Roller Bearing engineered for exceptional performance under combined radial and thrust (axial) loading. Featuring a 76.200 mm inner diameter and a 171.450 mm outer diameter, this bearing is crucial for high-stress applications in heavy industry, including primary reduction units, differential assemblies, wheel ends, and machine tool spindles. The geometry of the tapered rollers and raceways ensures true rolling motion and minimizes friction, providing optimal power transmission efficiency. Manufactured using high-grade, case-carburized steel, this assembly meets TIMKEN's stringent quality standards, offering superior fatigue life and reliability in demanding operational environments.
As a Senior Product Manager, I highly recommend this bearing set for MRO (Maintenance, Repair, and Operations) inventory where longevity and minimized downtime are paramount. The precise component matching between the 47620 cone and the 47686 cup guarantees accurate internal clearance and optimal load distribution when mounted correctly. Choosing genuine TIMKEN components ensures standardized performance characteristics, simplified installation procedures, and predictable service intervals, ultimately reducing the total cost of ownership compared to lesser quality alternatives. This bearing configuration is designed to deliver maximum operational uptime and robustness in continuous duty cycles.
