Jiaxing bearing group to bring you understand bearing lubrication

Jiaxing bearing group sales co. , LTD. Is a retail sales center located in jiaxing bearing group, for many years with outstanding specialized technology and credibility to provide services to the masses of users, jiaxing to introduce bearing lubrication bearing experts for you today. Lubrication on the fatigue life of rolling bearing, friction and wear, temperature rise, vibration and so on have important influence, not the normal lubrication, bearing cannot work. Analyze the failure reasons of bearing show that about 40% of the bearing damage is related to bad lubrication. Therefore, good lubrication of the bearing is an effective measure to reduce the bearing friction and wear. In addition, the bearing lubrication and cooling, sealing, rust and moderate impact of a number of roles, the effect of bearing lubrication can be briefly stated below: a. The contact between two rolling or sliding surface formed between a layer of oil film separates two surface, reduce the friction and wear of contact surface. b。 Using oil lubrication, especially the circulating oil lubrication, oil mist lubrication and oil lubrication, the bearing lubricating oil take most of the internal friction heat, effective heat dissipation effect. c。 Using grease lubrication, can prevent external dust and other foreign body into the bearings, sealing effect. d。 Lubricant function to prevent corrosion of metal. e. Extend the fatigue life of bearing. Bearing lubrication method is roughly divided into two kinds of grease lubrication and oil lubrication. In order to give full play to the function of the bearing, it is important to use according to the way and purpose, the lubrication method. Jiaxing bearing group for everybody below a brief introduction of the choice of grease lubrication and oil lubrication. When selecting a grease according to the working temperature, the main indicators should be drop point, oxidation stability and low temperature performance, drop point generally can be used to evaluate the high temperature performance, bearing the actual working temperature should be lower than 10 - drop point 20℃。 The use of synthetic grease temperature should be lower than 20 - drop point 30℃。 Based on choosing grease, bearing load of heavy duty should choose small grease penetration. When working under high pressure in addition to the penetration of small, must have high oil film strength and extreme pressure properties. According to the environmental conditions choosing grease, calcium base grease is not easy to dissolve in water, suitable for dry and less moisture environment. Under the condition of high speed, high temperature, lubrication has not timely can use oil lubrication. Through the circulation of lubricating oil, can take away a lot of calories. Is an important characteristic of lubricating oil viscosity, viscosity directly affect the liquidity of lubricating oil and the size of the friction surface is formed between the oil film thickness, the bearing working temperature of lubricating oil viscosity is usually 12 - 15cst。 Speed the Gao Yingxuan lower viscosity, the more load weight should choose high viscosity. Commonly used lubricating oil has high-speed machine oil, machine oil, turbine oil, compressor oil, transformer oil, cylinder oil, etc. Welcome to call the jiaxing jiaxing bearing more technical data bearing group sales co. , LTD.
