NTN Bearings Corporation manufactures and supplies a comprehensive range of bearings, constant velocity joints, and other industrial and automotive precision parts for a wide variety of applications, and across an array of various industries. 75 plants across the globe and more than 100 years of premium manufacturing renders NTN the third largest bearing manufacturer in the world.
In addition to a full line of bearing products, NTN produces tapered roller bearings that are designed for the most demanding applications in the toughest of industries– such as mining, steel manufacturing, and forestry. With almost 100 million tapered roller bearings manufactured each year by the NTN and Bower brands, it’s no surprise that NTN rivals all major competitors on the market. NTN tapered roller bearings feature conical rollers and raceways are arranged so that the rollers and raceways meet at a common apex, and rollers are guided by contact between the large end of the roller. They provide high capacity for radial and single thrust loads.
Why Choose NTN Tapered Roller Bearings?
NTN’s tapered roller bearings are industry best for many reasons, and here are a few…
Case Carburization– A process called case carburization creates a hardened steel casing around the outside of the roller bearing while leaving a softer core. This combo of hard surface layer and softer inner core provides next-level shock-load capabilities. Case carburization also increases the bearing’s life by up to 40%, resulting in less downtime, and increased maintenance intervals as well.
Premium Materials– Most of the line of NTN and all Bower® tapered roller bearings features case-carburized components. That means cups, cones, and rollers are fashioned from case-hardened alloy steel to provide reliability and superior fatigue life. Also, precise control of heat treatment, dimensions, and surface finish of the components even further contribute to superior bearing performance.
Local Manufacturing– NTN is proud to sell locally-manufactured tapered roller bearings to various markets. There are NTN-Bower facilities in Macomb, Illinois and Hamilton, Alabama, and NTN has been producing tapered roller bearings in the United States for more than half a century. On top of that, more than 10 million tapered roller bearings sold by NTN in the last year were created using domestic materials and some foreign components.
A Comprehensive Product Line– NTN also offers a full line of tapered roller bearings in ISO/metric, inch, and J-metric series with single row, two-row, double-row, and four-row assembly options available. Between NTN and Bower offerings, customers can optimize their selection by customizing surfaces and geometry to best suit their applications.
Roller Crowning– NTN’s pioneered the development of crowned rollers, which have resulted in greater load-carrying capability and longer life for these roller bearings. Crowned rollers under load distribute stress equally along the full length of contact made with raceways, thereby eliminating stress concentration at the roller ends. This clever design concept also compensates for minor misalignment between shaft and housing bore.
