Timken Tapered Roller Bearings Guide
Product description
The 33889 / 33821 Timken tapered roller bearing features a single-row design consisting of an inner ring assembly (cone), an outer ring (cup), and a single row of tapered rollers. This configuration provides reliable radial and axial load support, high rigidity, and stable performance under demanding operating conditions. The separable cone and cup design allows convenient mounting and adjustment, while the bearing can be set to the required endplay or preload during assembly to optimize operating performance.
The 33889 / 33821 bearing is widely used in automotive applications, transmission systems, machine tool spindles, pumps, agricultural machinery, construction equipment, and other industrial applications. It is particularly suitable for applications requiring controlled bearing clearance or preload, accurate shaft positioning, and reliable support for combined radial and axial loads.
