Makes the bearing card: what circumstances bearing suits to use

Eccentric bearing consists of outer ring, inner ring, rolling basket, rolling body, whose character is: the inner ring of the inner hole for the eccentric hole, in the inside of the eccentric hole wall with vertical keyways.
Bearing grade silicon nitride of rolling element density is lower than the same size of the bearing steel rolling body %, this means that the light weight, small inertia, superior performance, rapid start-up speed is higher.
High alloy steel is segmented, slow heating guaranteed, how can the roller coaster is according to the track on the left turn, right turn, turn, reflexed?
The reason is the trunk between the trunk and one artifact.
Reason is mainly due to bad installation, axis deflection, journal and low accuracy of the shell hole, take measures to ensure that the bearing installation quality and enhance the axial runout precision of shoulder and shoulder.
Traditional repair mode for roller roller body wear and bearing, bearing housing and other transmission parts wear and tear, the traditional process often use after repair welding machine, or use the technology for processing such as electroplating, but no matter what technology, its major weakness is equipment must be a lot of demolition of transportation, the investment of manpower is larger.
Between shaft and hole surface sliding trace of inner ring end face and shoulder friction heat crack when the 'inner circle', the sliding friction between inner ring and the shaft will produce high temperature, due to the inner ring end face and shoulder interface is small, the temperature will be higher.
Mm, interference when assembling, many manufacturers will think that is a question of NSK bearings, through our continuous publicity, motor factory now have realized mainly is a question of insulating varnish.
Corrosion protection: to prevent air and water on the corrosion of the component, if the bad seal, valve oil baffle ring of engine failure can cause oil leakage, such as also can accelerate the consumption of oil.
Common vibrating screen as bearing cylindrical roller bearing and spherical roller bearing, the solution: use thin oil lubrication, improve lubrication channels, improve the sealing structure.
Current corrosion caused the main reason is that the potential difference between the outer and inner ring and electrostatic effect, the solution: in setting circuit, current is not through the bearing, bearing for insulation, electrostatic grounding.
As the application of high temperature grease were focused on two kinds of situations, the first is to maintain the industry including, coal-fired power plants, steel mills, brick, cement plants, chemical plants, heating companies such as bearing high temperature of heat source in contact with the equipment.
So bad as lubricating oil used in the process of dryer can not adapt to run high temperature environment, leads to the formation of a lubricating oil film or can't effectively lubricating oil film, lead to run bearing lubrication is not free.
