Tapered roller bearings are a type of rolling element bearing that feature inner and outer raceways with a segmented cone shape, as well as tapered rollers. They can support both radial and axial loads, as well as thrust loads, making them suitable for strenuous and challenging operating conditions. These bearings
commonly feature reduced temperature spikes during the running-in period, as long as they are properly lubricated and mounted. Other advantages include reduced friction, minimal heat generation, even load transfer while rolling, reduced wear, and extremely low maintenance requirements. The complete machinery
features a cone assembly and a cup, which is the outer ring of the bearing; the cup can be separated from the rest of the assembly to facilitate mounting and allowing for interchangeability. Common applications for tapered roller bearings include car wheels, gearboxes, propellers, railroad axles, engines and reducers, mining, and construction industries. They are available as single row, double row, four row, or complete assemblies for specific applications. As with all bearings, they can be made in a variety of materials, such as sheet steel, polyamide, brass, or machined steel, to impact bearing performance. Steel and brass typically provide more durability and load capacity, while plastic composites can provide higher speed capabilities, but may not be suitable for high temperature applications. Additionally, a variety of contact angles are available, which impacts the load capacity of the bearing; larger contact angles result in higher load capacities. MRO Supply carries a formidable range of tapered roller bearings, of varying materials, designs, sizes, and manufacturers, to suit any application.
