47620/47690 Tapered Roller Bearing Set | 1.625" Bore, 3.543" OD | High Load Capacity CR Standard
The 47620/47690 is a single-row tapered roller bearing set engineered for demanding industrial and automotive applications. This standardized inch series bearing (CR/Timken interchange) is specifically designed to handle simultaneous high radial and high axial loads by orienting the rollers and raceways so that loads are distributed uniformly across the components. Key specifications include a bore (d) of 1.625 inches (41.275 mm) and an outer diameter (D) of 3.5433 inches (90.000 mm), providing robust performance in gearboxes, differential assemblies, and heavy-duty wheel ends. Constructed from high-quality case-hardened steel, the 47620 cone (inner ring) and the 47690 cup (outer ring) offer exceptional wear resistance and extended service life even under sustained shock loads or misalignment.
This bearing set is the definitive choice for maintenance professionals seeking reliable durability and precise dimensional stability. The separable nature of the components simplifies installation and allows for easier inspection and maintenance procedures. Our 47620/47690 units adhere to stringent quality control standards, ensuring predictable performance and minimizing unplanned downtime. By choosing this industrial-grade component, customers benefit from superior operational efficiency, reduced friction, and long-term cost savings associated with less frequent replacement cycles. Ideal for replacement or original equipment manufacturing (OEM) integration in pumps, crushers, and material handling systems.
