The Timken HM89443 is a single-row tapered roller bearing cone with a 1.3125 inch bore, 3 inch cup outer diameter, and a cone width of 1.1563 inches. It belongs to the HM89400 series and is designed for use in demanding radial and axial load applications including gearboxes, hoisting equipment, rolling mills, drive axles, steer axles, and similar industrial and heavy-duty machinery. The cone assembly consists of the inner ring, tapered rollers, and cage. The tapered roller geometry allows simultaneous radial and thrust load handling, making this series well suited to applications with combined loading requirements. This cone is compatible with the Timken HM89410 cup (outer ring) as part of the matched set identified as HM89443/HM89410. Published bore dimensions are 33.37 mm (1.3125 inches), outer cup diameter 76.2 mm (3 inches), and assembly width 29.37 mm (1.1563 inches). The item is presented in original Timken orange packaging with the part number HM89443 printed on the label. Maximum shaft fillet radius is 0.030 inches. Timken is a US-headquartered manufacturer with over a century of history in tapered roller bearing design and production. The HM89443 cone is cross-referenced as a differential pinion bearing in automotive applications and as an industrial bearing cone in machinery and powertrain contexts.
