Technical data of bearing

Bearing the technical data of 1) Bearing lubrication effect of lubrication on the fatigue life of rolling bearing, friction and wear, temperature rise, vibration and so on have important influence, not 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 bearing friction and wear. In addition, bearing lubrication and cooling, antirust and seal, a variety of action such as moderate impact. 2) Grease lubrication grease is composed of base oil, thickener and additive of lubricants. When the choice, should choose to use condition is very suitable for bearing grease, because the trademark is different, also there will be a very big difference on performance, so when the choice, must pay attention to. Bearing commonly used grease has calcium base grease, grease sodium, sodium calcium base grease, lithium base grease, aluminium base grease and molybdenum disulfide grease, etc. Number of filling grease in the bearing to 1/2 - full of bearing internal space A third as appropriate. When high speed should be reduced to one third. Too much grease will lead to higher temperature rise. 3) Oil lubrication under the condition of high speed, high temperature, lubrication has not timely lubrication can be used. Through the circulation of lubricating oil, can take away a lot of calories. 4) Viscosity 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 - 18cst。 Speed the Gao Yingxuan lower viscosity, the more load weight should choose high viscosity. Commonly used lubricating oil machine, high-speed machine oil, turbine oil, compressor oil, transformer oil, cylinder oil, etc.
