Timken Tapered Roller Bearings Guide
Product Description
The 28159 / 28318D TDO tapered roller bearing features a double outer ring design with a single inner ring and two rows of tapered rollers. This configuration provides high radial load capacity, bidirectional axial load support, and excellent rigidity for demanding operating conditions. The double outer ring structure improves roller guidance and load distribution, helping maintain stable operation under heavy loads, shock conditions, and continuous running requirements.
The 28159 / 28318D TDO bearing is widely used in industrial gearboxes, heavy-duty transmission systems, rolling mills, mining equipment, and construction machinery where reliable load support, accurate positioning, and long service life are required.
