Tapered roller bearings are used in a variety of industrial applications. The tapered rollers allow the bearings to accommodate heavy radial, axial and combination loads. This loading flexibility combined with a variety of configurations can be designed from single cups, double cups, and cones. This is why tapered roller bearings are designed into almost every industry, particularly large diameter tapered roller bearings.
Tapered roller bearings are uniquely designed to manage both thrust and radial loads. Consisting of a "tapered cup" and a "tapered cone", this design is one of the most basic and common styles in the bearing industry. Found in everything from cars to conveyor lines, tapered roller bearings are more versatile than any other bearing series. Our taper bearings are sold in sets with both the cup and the cone together.
tapered roller bearings are designed for the most demanding applications in industries such as mining, forestry and steel manufacturing. Utilizing conical rollers and raceways arranged so that the rollers and raceways meet at a common apex, NTN`s tapered roller bearing rollers are guided by contact between the large end of the roller, providing high capacity for radial and single thrust loads. With almost 100 million tapered roller bearings manufactured every year under the NTN and Bower brands, it`s no wonder that NTN rivals all major competitors on the market.
We offer premium tapered roller bearings under the NTN and Bower® brand names. Most NTN and all Bower® tapered roller bearings feature case-carburized components. Cups, cones, and rollers are made from case-hardened alloy steel of [Bearing Quality" to provide superior fatigue life and reliability. Precise control of heat treatment, dimensions, and surface finish of the components further contribute to reliable bearing performance. So whether you`re looking for an American-made, case-carburized inch series taper, or a metric series through-hardened variety, we have you covered with a proper fit for your application. Premium steels and heat treatments are also available for applications requiring extended life and high reliability.

As the main bearing bush and connecting rod of sliding NTN bearing; the most common problem in the application is the peeling or burning of the wear-resistant alloy layer; and the early wear of the bearing. If the diesel engine passes short-term work; the outer surface of the bearing bush is agile or severely worn; Most of the reasons are not in the bearing shell itself; firstly due to the application of conditions or poor cooperation parts or skills, there is a query data; the reason for bearing damage is 44.9% is formed by impurities; 13.4% is installed Bad; 12.7% is too concentric; 10.8% is smooth; 9.5% is overload; others are corrosion and other factors. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
The diesel engine is in the process of starting and parking; the NTN bearing is often in a critical smooth condition; the oil film can be connected continuously; the friction surface is directly touched. Even if the diesel engine is in normal operation; due to unstable load, etc.; the journal and the bearing are also difficult to adhere to. And the liquid that is not connected is smooth. Others; the new diesel engine fails to completely remove the molding sand and iron filings during installation; it can enter dust and dirt during the working process; it is also the accelerated wear; the primary cause of the formation of the lava.
The shedding of the NTN bearing is mainly due to fatigue damage. The size and direction of the bearing are changed with time; when the load is unstable; the oil film of the oil film is not evenly adhered to the bearing friction; In the case of minimum oil film thickness; high temperature occurs in part of the bearing surface; greatly reduces the fatigue strength of the alloy layer. Others; NTN bearing itself is poorly fabricated and installed; it is also the direct cause of the alloy layer falling off.
In addition to wear and tear; the corrosion of sliding NTN bearings is also a significant problem; this depends primarily on the quality, temperature, pressure and bearing load of the oil. The high load of the bearing is the simplest to show corrosion; while the smooth oil is transformed at high temperatures. The resulting organic acids and sulfides are the direct cause of bearing corrosion.
The burning of NTN bearings; that is, the so-called "burning tile"; the primary reason is that the gap is over.
