Choose bearing grease skills - bearing knowledge

Bearing grease the stand or fall of choice for the stable operation of the equipment has a close relationship with, in order to better play to the bearing in the best condition, choose bearing grease must consider from the following aspects: 1, rust resistance, used in grease in the bearing must have antirust effect, rust inhibitor is best can not dissolve in water. Grease should have good adhesion, and can form a layer of oil film on the surface of steel. 2, mechanical stability grease in machining will become soft, cause leakage. During normal operation, oil will by the bearing to the bearings. If the mechanical stability of the oil is insufficient, operation process, the structure of the soap grease causes mechanical disruption of oil was damage, and loss of lubrication. 3, oil seal oil seal is necessary to protect bearings and lubricants from the barrier of contamination from, bearing in the process of operation, regardless of debris or moisture can penetrate bearings, { TodayHot} In case of causing damage to its. Have a bearing on the correct installation and maintenance is an important factor of the longest service life. At the same time, must pay attention to the correctness of the purity of the bearing, bearing selection and choose the proper installation and maintenance tools. In addition, the bearing must prevent polluted by contaminants and moisture, and ensure that the right be installed and lubrication. Therefore, the design of the bearing arrangement, the condition of the oil seal, type of lubricants and lubrication cycle, and special maintenance are the same and important role. 4, mix oil never mix the fat off from the incompatible, if two incompatible oil mixture, usually will soften its consistency, might end up bearing damage caused by oil easy to loss. If you don't know what kind of grease bearing used is, you must first thoroughly remove bearing inside and outside the old grease, can add new grease. According to the classification of 5, grease main distinguish between temperature and working conditions: grease can be classified according to their allowable working temperature, lubrication grease consistency and ability is affected by temperature, operating under a certain temperature bearing must choose under the same temperature has the correct consistency and good lubrication effect of oils and fats. Oil is made of different working temperature range, can be roughly divided into low, medium temperature and high temperature with grease. { HotTag} At the same time, there is a certain type of oils and fats known as resistance to squeeze or extrusion and add molybdenum disulfide, at the same time, among them with additives to enhance the strength of the lubricating oil film. 6 if the wrong choice, and the choice of grease important factors grease all measures to prevent bearing is useless, choose a grease, its oil viscosity in working temperature is it is important to be able to provide adequate lubrication effect, viscosity is mainly affected by temperature, it with the temperature rising and falling, is that it increased when the temperature decreases. Therefore, you must know when working temperature of the oil viscosity. Machinery manufacturers are usually specified use some grease, however most of the standard grease applicable range is very wide. The following important factors is that the choice of grease: mechanical type; Bearing type and size; Working temperature; Working load; Speed range; Work, such as vibration and the direction of the main shaft is horizontal or vertical. Cooling condition; The sealing effect; Peripheral environment.
