KOYO Automobile Wheel Hub Bearing Installation Technology Determines The Service Life

Approximately 25% of all premature koyo bearing failures are caused by improper installation or incorrect use. Various applications may require heating, mechanical or hydraulic installation methods to properly and efficiently install automotive wheel hub bearings. Selecting the right installation method for the application will help extend the life of the bearing and reduce the cost of premature bearing failure and potential damage to the application.

1. Bearing heat installation method

Oil bath heating of the bearing may contaminate the automotive wheel hub bearing and cause premature bearing failure. Induction heating is the most common means of heating koyo bearings today because of its high controllability, efficiency and safety. Some bearing manufacturers have established standards for the development of induction heaters for bearing applications. Automotive wheel hub bearing induction heaters have many features that help prevent damage to the bearing during the heating process.

2. Bearing cold installation

In general, most small and medium-sized bearings are cold installed. Traditionally, bearings are installed with a hammer and a section of old pipe. This practice can cause external forces to be transmitted through the rolling components, thereby damaging the raceway. The bearing installation tool applies external forces to the bearing rings with a press fit, which helps prevent bearing damage.

3. Hydraulic installation of bearings

Koyo bearings are pioneers in the use of hydraulic technology in installation, including oil injection and drive-tight installation. These methods can help simplify bearing configuration and help to install bearings correctly and easily. Automotive wheel bearing companies have also developed many tools and equipment for hydraulic installation of bearings to put these hydraulic technologies into practice.

There are many reasons for the premature failure of automotive wheel bearings, but the main ones are improper use and maintenance and improper lubrication, poor lubrication, pollution overload, collision and impact during assembly, transportation and disassembly. Pollution is caused by man-made factors such as the lack of fine cleaning of disassembly tools.

The influence of matching clearance, the gap between the shafts is too large, and relative movement occurs between the two. First, the clearance of the matching shaft segments is too large, and finally the automotive wheel bearings are scrapped: second, cracks are generated in the bearings, affecting the accuracy of movement. These reasons cause premature failure of bearings, which are all detrimental to our actual work. Therefore, it is of great practical value to study how to avoid premature failure of Koyo bearings and extend their service life.

The most effective way to prevent premature bearing failure is to avoid the various factors analyzed above and the conditions that contribute to these factors as much as possible: First of all, when selecting koyo bearings before use, you should consider the size of the noise, the size of the rigidity, the size of the radial crack of the bearing, the size of the torque, etc. The choice of lubricating oil depends on the working environment of the automobile wheel hub bearing. Different lubricating media produce different noises during use.
