The HM 89448/89410 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 36.512 mm inner diameter, 76.2 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 23.02 mm and an inner ring width of 28.575 mm. The internal geometry is fine-tuned for durability, featuring R1 radius of 0.8 mm and R2 radius of 3.3 mm for optimal roller contact and smooth operation under variable loads. Weighing only 0.646 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.
