The 3386/3320 RICH is a top-tier single row tapered roller bearing designed to deliver outstanding strength, reliability, and precision in high-demand environments. With exacting dimensions of 39.688 mm inner diameter, 80.167 mm outer diameter, and a total width (T) of 29.37 mm, this bearing is tailored for assemblies exposed to intense radial and axial forces—making it indispensable in industrial transmissions, off-highway machinery, agricultural drivetrains, and automotive powertrains.
Its robust construction includes an outer ring width (C) of 23.812 mm and an inner ring width of 30.391 mm. The internal geometry is fine-tuned for durability and smooth operation under variable loads. Weighing only 0.644 kg, it offers the perfect balance of lightweight handling and heavy-duty capability.
Engineered by RICH and manufactured in China, this bearing's separable design—with independently mountable cone and cup—ensures streamlined installation and simplified servicing. Whether used in gearboxes, axles, or hubs, it provides enduring performance, reduced friction, and consistent power transfer in the most challenging operational settings.
