NTN Cup and Cone Tapered Roller Set - SET415

If you're looking for roller bearings, cups, cones and other components that perform for you mile after mile, look no further than NTN. Tapered roller bearings from NTN use conical rollers and raceways that are designed so that the rollers and raceways meet at a common apex. The large end of the roller and a rib on the inner ring guides the rollers. This results in high capacity for radial and single thrust loads. Precise control of heat treatment, dimensions, and surface finish of the components also contribute to industry-leading bearing performance. So whether you're looking for an American-made, case-carburized inch series taper or a metric series variety, NTN has you covered with a proper fit for your application's specific needs. Premium steel types and heat treatments are also available for applications that require extended life and high reliability.

NTN/Bower products are warrantied for 1 year from the date of purchase, though exceptions for some products may apply.

NTN began in 1918 when investor Noboru Niwa, his company Tomoe Trading Co., and engineer Jiro Nishizono came together to design and manufacture the first NTN ball bearings. NTN Bearing Corporation of America was established in 1963 to support the sales of NTN bearings in the American market. By this time, NTN had the capacity to manufacture ball bearings, spherical, tapered, cylindrical, and needle roller bearings and automotive constant velocity joints. By the middle of the 1980s, NTN acquired the Bower brand and expanded the company's catalogue of tapered and cylindrical roller bearings. Ten years later, NTN acquired the BCA brand to round out its product line with automotive clutch release bearings and specialty agricultural bearing assemblies.
