Well known scroll TIMKEN bearings performance depends to a large extent, its material properties. As the world's largest manufacturer of ball bearings bearing low alloy, high-purity groups usually quenching chromium steel as a material for manufacturing of bearing rings and rolling elements.
Making suffered high combat loads with carburizing steel bearings and alternating bending stress. We find that, due to the constant enhancement of the quality of bearing steel (although costs are rising), to TIMKEN bearings of carrying abilities significantly. Research results and practical experiences have proved that now scales made of rolling bearing steel bearings, lubrication good, clean environment and loading is unlikely circumstances, has to reach the infinite exhausted strengths.
Punishment of heat treatment technology of bearing rings and rolling elements assure bearing up to 150 degrees, size firm. Dealing with something much higher temperature, need to use a special heat treatment of penalty points. If bearings use in corruption, environment, necessary bearing steel have engaged in corruption. TIMKEN bearings in stainless steel scales number prefix "s" and the suffix "W203B". This bearing and body tensions hardened bearing steel bearing size and hosting skills are identical. Anti-corruption in order to link it skills in the placement and use in the process of their appearance cannot be damaged. Production of ceramic spindle of silicon nitride ball bearings. Ceramic balls are much lighter than steel balls, centrifugal force and friction than small steel balls. The TIMKEN bearing when lubricating grease can still reach a very high speed and long life, low temperature.
