Reasons and maintenance methods affecting the service life of IKO self-aligning ball bearings

First of all, the bearing size is limited.

Self-aligning ball bearings usually have limited installation space. In most cases, it is based on mechanical design or other design limitations. The type and size of the IKO bearing is therefore based on the decision to choose the bearing diameter. Therefore, the main dimension tables of standard self-aligning ball bearings are sized according to international standards.

In many forms of standard bearing sizes, it is best to use standard self-aligning ball bearings in mechanical equipment design, size, and direction are constantly changing. Normally, the basic load rating is shown in the size of the table. However, axial load and radial load can also be an important factor in selecting an appropriate self-aligning ball bearing. IKO bearings usually have a high load capacity and are subject to large vibration and shock loads when the size is quite long.

Second, the speed of the bearing.

The allowable speed is determined based on factors such as the type, size, accuracy, cage, load, lubrication, and cooling method of the self-aligning ball bearing. The IKO bearing table lists the speeds allowed for the standard accuracy of lubricating oil bearings and grease. In general, deep groove ball bearings, self-aligning ball bearings and cylindrical roller bearings are suitable for high speed applications.

Third, self-aligning ball bearing tolerances.

Self-aligning ball bearings are dimensionally accurate and rotationally accurate based on the International Organization for Standardization (ISO) and JIS standards. High precision, high speed machinery, recommended for five years or more accurate self-aligning ball bearings, deep groove ball bearings, angular contact ball bearings or cylindrical roller bearings for high machine running accuracy. Rigid, elastically deformed when the contact pressure of the ball and roller races is adjusted. Some machines require less elastic deformation. There is a small elastic deformation than a ball bearing roller bearing.

Maintenance of IKO bearings must also master the following:

1. Regularly check the use status, pay attention to whether there is abnormal sound and partial sharp temperature rise in the observation part;

2. Regularly or quantitatively add lubricating oil or grease as required;

3, according to the use of the vehicle, at least once every six months to completely replace the lubricant, and carefully check;

4. Inspection method under maintenance condition: clean the kerosene or gasoline under disassembly, carefully observe whether there is sliding or creeping phenomenon on the inner and outer cylindrical surfaces, whether there are flaking or pitting on the inner and outer raceway surfaces, whether the rolling elements and cages are Wear and deformation, etc., based on the comprehensive situation of IKO bearing inspection, to determine whether it can continue to use.
