The Characteristics of the nsk bearings

The Characteristics of the nsk bearings

The nsk bearings can form a very compact axial bearing configuration, which can withstand heavy axial loads, is insensitive to impact loads, and has good rigidity. FV produces unidirectional thrust tapered roller bearings and bidirectional thrust tapered roller bearings. The screw-fixed bearing forms a specially designed unidirectional tapered roller thrust bearing and is filled with rollers.

This kind of bearing is used for the screw-fixed bearing configuration of the rolling mill. FV nsk bearings has logarithmic contact lines between raceway and roller to ensure optimal stress distribution in the bearings, thus extending bearing life.

The domestic manufacture of the nsk bearings will be completed by china FV BEARING INDUSTRIES in 2021. Look forward to our achievements. FV Bearing can not only produce standard models to replace well-known international brands, but also make design improvements according to the specific requirements of customers. If you have any requirements for the nsk bearings, please send an email to sales@fv-bearing.com

In fact, FV can now provide the nsk bearings of various designs to continuous casters. Including Spiral spring bushing bearing, Spherical roller bearing, RUB needle roller bearing, SKF - CARB bearing, etc. However, with the continuous upgrading and innovation of the industry. Timken\'s nsk bearings are widely used in steel plants in China, India, the United States, and other countries. FV bearing is designed to meet the requirements of steel mill users. FV has studied the nsk bearings since 2020.  It is expected that the great project of localization of adapt bearings will be completed in 2021. This is beneficial to the steel plant. FV bearings save huge production costs for global steel plants.

Because the rolling body of thrust tapered roller bearing is a tapered roller, the rolling busbar and the raceway busbar of the gasket converge at a certain point on the axis line of the bearing structurally, the rolling surface can form pure rolling and the ultimate speed is higher than that of thrust cylindrical roller bearing.

Due to the small production of nsk bearings, most of the models produced by various factories are non-standard external dimensions, while the series of standard external dimensions are less produced, so there is no national standard for the external dimensions of this kind of bearings.

The Detection of nsk bearings Radial Clearance

According to the functional characteristics of the nsk bearings and the difference in operating conditions, after selecting the appropriate bearing structure type, the bearings need to be checked routinely. These checks include the specifications and machining accuracy of the bearing and assembly parts, the quality of the lubrication, and the parts are worn out or not, etc.

Of course, after checking the bearing, the following operations should be carried out:

The first is to clean the bearings. One point to note is that the nsk bearings with sealed equipment can omit the cleaning process, because the cleaning will cause the intrusion of foreign matter inside the bearing and affect the normal use of the bearing;

Second, it is necessary to adhere to the monotony of the bearing. For bearings that need to be cleaned, after cleaning the rust inhibitor on the bearing, it is necessary to dry the bearing, otherwise, it will easily cause the bearing to rust;

The third is to adhere to the lubrication degree of lubrication.

In addition to the inspection work before the bearing equipment, the radial clearance of the bearing should also be tested. Radial clearance mainly includes the original clearance of the nsk bearings under natural conditions, the cooperative clearance that causes the original clearance to change after the bearing equipment, and the actual operating clearance formed under the effect of temperature and load. Since the size of the radial clearance directly affects the operating temperature, oscillation, and service life of the nsk bearings, the detection of the radial clearance of the bearing is particularly important.

The nsk bearings radial clearance measure

Regarding different bearings, how to measure the nsk bearings radial clearance?

1. The measurement of radial clearance needs to use special instruments to measure things as much as possible. When there is no special instrument on hand, a feeler gauge and other things can be used for measurement. When using the manual measurement method, this method has higher requirements on the measurer and is a method prone to error, so it is generally not recommended to use it.

2. For double-row and four-row rolling bearings, the clearance requirements for each row are very important, and it is necessary to test them all.

3. During the measurement, make sure that the rollers of the bearing fall into the bottom of the groove.
