Bearing is invalid smooth four big drawbacks

Some smooth bearing use need not stop in the process of disposal, this is called smooth oilless bearing, and there are a lot of bearing needs to stop smooth maintenance in use, and this can smooth correctly is very important, if you stopped smooth for bearing, but do not reach the designated position, is called the invalid is smooth, it will bring a lot of disadvantages to bearing.     China bearing network explanation bearing four disadvantages: invalid smooth & emsp;   The first: color & emsp;   Metal to metal contact can make through the high bearing temperature, incur raceway and roller discoloration. Under mild conditions, the color was due to the smooth agent pollution of bearing appearance, and in severe cases, metal discoloration due to high temperature. Under all conditions, early detection can prevent costly repairs.     Due to the bearing surface smooth agent pollution color & emsp;   The second: scratches and flake & emsp;   Check the bearing whether have cut into the trace of metal or metal flake - — These conditions needs attention immediately. In high load and low speed applications or continued under the condition of high temperature show scratches and spalling, and smooth thin oil film or lack of will accelerate the onset of problems. Lack of smooth, smooth fat or choosing the wrong suddenly changes in working conditions can cause bearing materials peeling or bearing guard Nick.     Third: roller overheating & emsp;   Light synovial membrane rupture between components will incur some scratches in direct contact. In tapered roller bearing, which could show the scratches on roller large end and lead guard. Metal to metal contact on thermal damage to the formation of tapered roller & emsp;   Fourth: bearing complete lock & emsp;   Part of extreme heat will be produced in the bearing metal, change bearing the original material and geometry structure. This can cause excessive roller tilt, adhere to the damage and bearing complete deadlock. If indeed catastrophic damage, initiative consulting bearing experts to the basic reason of the problem, because the elements can be smooth.     Warm prompt: smooth bearing void formation damage on the appearance and effect the performance of the bearing have very big difference. In all cases, it is necessary for the smooth bearing system design right amount of fat, type, grade, viscosity, additives and feed system. Should be based on the historical experience, load, speed, sealing system, using conditions and smooth life expectancy to choose fat. If not appropriate to think these elements, bearing performance and application effect may be lower than expected.
