Ability to correctly select KOYO bearings, can host for good work performance and prolong life; on whether companies can shorten the repair time, reduce maintenance costs, total operating rate, has a very important role. In General, select KOYO bearings of the steps may be summarized as follows:
Depending on the bearing operating conditions (including loading, speed and load type, lubricated, coaxial degree requirements, registration or non-registration, installation and maintenance of the environment, environmental temperature, and so on), select the type of ball bearing, tolerances and clearance level;
Depending on the bearing conditions and conditions of work and life, through the calculations to determine bearing type, or according to the requirements, bearing type is selected, and then checking for life;
Select KOYO bearings the main considerations are the speed limit, requiring Dacron life and load carrying capacity, other factors will help to determine the bearing type, structure, size and tolerance grades and clearance work to find the final plan.
1, KOYO bearings caused poor lubrication is one of the main causes of premature damage. Major causes include: no equipment lubrication or lubricant in a timely manner; lubricants or lubricant is not filling in place; lubricants or lubricant improper selection; incorrect lubrication, and so on.
Recommendation: choose the right lubricants or lubricant, using the correct lubrication of filling.
2, bearing improper installation, use brute force when it was installed, direct percussion with a hammer bearing bearing damage the most, is the main cause of deformation of bearing installation is not in place, install the biased or not attached to the bearing, causing KOYO bearing clearance is too small. Inner and outer rings are not in the same center of rotation, resulting in different hearts.
Recommendation: select appropriate KOYO bearings or professional installation tool, installed using special instruments and detection.
3, pollution can also cause premature damage of KOYO bearings. Pollution of dust, metal chips, etc into the bearing. Major causes include: open bearing prematurely before using packaging, pollution; installation work environment is clean, pollution; bearing's working environment is clean, medium pollution, and so on.
Recommendation: the packaging before use it is best not to open the KOYO bearings; installed when you install the environment clean to clean the bearings to be used; enhanced KOYO bearings sealing device.
On request once the final value of rated load, you must consider the bearing dimensions required for the installation, included here are considering the installation of bearing and fixed. And have the required shaft size that matches the load rating of the bearing size. These factors help to determine the structure and size of the bearing, you can also exclude certain bearing types. In some cases, due to space restrictions ruled out even rated load prior to the choice.
