Rolling bearing performance depends to a large extent, its material properties. SKF bearings are normally low alloy quenching chromium steel for manufacturing as a whole, high purity materials for bearing rings and rolling. Subject to high shock loads and alternating bending stresses bearing carburizing steel.
In recent years, due to constantly improve on the quality of bearing steel (rising prices), FAG bearings are bearings of carrying capacity significantly. Research results and practical experience have proved that today's standard of rolling bearing steel bearings, lubrication of less good, clean and load cases, has infinite fatigue strength can be achieved.
NSK bearings rings and rolling elements of heat treatment technology to ensure bearing 150 degrees or less, and dimensional stability. For higher operating temperatures, you need to use a special heat treatment method. If the bearings are used in a corrosive environment, you need to have corrosivity of bearing steel. Stainless steel standard bearing the code name prefix s; and the suffix-W203B.
Overall hardening of the TIMKEN bearings and steel bearing the main size and carrying capacity of the bearings is the same. In order to maintain its ability to resist corrosion, in the process of installing and using the surface cannot be damaged. Silicon nitride ball bearing production for ceramic spindle bearings.
Ceramic Ball far lighter than steel balls, centrifugal force and friction than steel balls significantly smaller. This INA bearings grease lubrication may still reach a very high speed and long life, low operating temperatures.
