Although a simple truck bearing seal cover is removed, it will not cause serious safety hazards such as vehicle shaft cutting or derailment, but due to the bearing seal cover falling out, the hot shaft rises quickly and the temperature is high. Infrared equipment predicts strong heat and more heat. , Most of them stopped on the ...

The metallurgical quality of the bearing material used to be the main factor affecting the early failure of KOYO bearings. With the progress of metallurgical technology (such as vacuum degassing of bearing steel, etc.), the quality of raw materials has been improved. The proportion of raw material quality factors in bearing fail...

First, the limitation of bearing size. Usually, the space in which NTN imported bearings can be installed is limited. In most cases, the shaft diameter (or bearing inner diameter) is based on mechanical design or other design constraints. Therefore, the choice of bearing type and size is determined according to the inner diamete...

Due to the inaccurate measurement of the shaft diameter and the size of the bearing seat hole or the mating surface roughness does not meet the standard requirements, excessive interference fit is caused, and the nsk bearing seat ring is greatly squeezed, which causes the radial clearance of the bearing itself to decrease , Make...

Bearings have many failures, and many users who use bearings have experienced this. After the bearing has been running for a period of time, it is necessary to check whether there is any problem, and pay special attention to whether the bearing fails. The main reasons for failure are as follows: 1. Contact fatigue failure Contac...

Checking the condition of the machines in operation and preparing a thorough inspection plan has become more and more serious. Among them, the bearing is the focus of attention, because it is the most important rotating part in all machines. Condition monitoring is an important part of preventive maintenance. Early detection of ...

Whether the NSK bearing is installed correctly will directly affect the accuracy, life and performance of the bearing during use. (1) When cleaning a large number of NSK bearings, first use hot machine oil at a temperature of 90～100℃ to melt the encapsulating oil. At the same time, use a seamless and chip-free tool to dig ou...

NSK bearings use water-soluble cutting fluid, and users must pay more attention to machine tool maintenance and management to control the generation of corrosion and even eliminate corrosion. In order to prevent water from corroding the metal surface, the machine tool should be lubricated with sufficient oil frequently, and grea...

(1) Temperature conditions during measurement The ambient temperature during measurement is specified as 20C. The temperature of FAG bearings, gauge blocks, standard parts and measuring instruments must all be the same. The above method of putting them on the same metal plate can quickly achieve the necessary temperature balance...
