Wheel bearing lubrication and seal

Effective and sufficient for bearing ( 轴承) Applying the lubrication ( lubrication) And effective sealing is to assure the safety of bearing operation ( 旋转) The necessary measures and early avoid non-normal damage. Thin wall bearings manufacturer of angular contact ball bearings can match the optimal number of balls and the contact Angle of 30 °. They support radial load is higher than contact bearing deep groove ball bearings or four o 'clock, and can support comes from the same direction of axial load. In view of the special demand, bearing lubrication bearings ( 轴承) Mostly in the overloading low speed working condition ( 挑剑) The general condition (work, 条件) Under the filling of lubricating oil lubrication type of bearing with lubrication can be obtained very satisfactory results ( 效果) Commonly used grease have calcium ( Ca) Grease, lithium base grease, aluminium base grease and high temperature ( 高温) Grease and so on, the user can choose according to the specific situation, 选择) The most suitable grease. As shown in table 1 for the grease recommended choose brand. Wheel bearing seal ( 密封) Wheel bearing ( 轴承) The seal on the one hand is to prevent have filling lubrication ( lubrication) Grease leak outward, on the other hand, in order to prevent external dust, impurities and water invasion of bearing internal and affect their normal work, 工作) 。 Such as cross section thin-walled bearing has realized the extremely thin cross section of the bearing, also has realized the product miniaturization, lightweight. The diversity of products extends its application scope. It is generally divided into glue sealing - RS, iron seal - ZZ, plane, canvas - K, copper - M。 Because the wheel bearing mostly in overloaded work under low speed, so the bearing seal with rubber sealing ring seal and labyrinth seal two structures ( 结构) 。 The rubber sealing ring seal itself has simple structure, take up the space ( 空间) Small, sealing performance ( 兴能) The advantages of reliable and has been widely used, 应用程序) , but its deficiency is in the high temperature ( 高温) State rubber sealing lip early aging and loss of sealing, so the work under the working conditions of high temperature of wheel bearing appropriate USES labyrinth seal. 宁波SUNTHAI轴承f An article on F: analysis of application of wheel bearing in various fields: next article bearing main dimensional accuracy and rotation accuracy
