Jiaxing bearing small make up take you to learn the spindle bearing when choosing grease required

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. Spindle bearing grease is a precision machine tool spindle bearing special lubricating oil and similar equipment, it to ensure the accuracy of the spindle work and use of performance, prolong its service life plays a very important role, is also called the bearing oil. So in the choice of the bearing grease performance requirements? 1, good lubricity to keep between shaft and bearing contact surface have a uniform oil film, and in the main shaft impact load of oil film start or stop the movement also not dent, keep good lubrication performance, play to reduce friction and friction heat, lowering the temperature rise of the main shaft, ensure the machining accuracy, oil has good lubricity. 2, good rust resistance due to the oil in the working process of the spindle lubrication system will inevitably mixed with condensed water or machine cooling fluid in the air, so the oil has good rustproof, especially in hot and humid climate in the south area, pay particular attention to the rust protection. 3, good oxidation resistance of the machine tool main sleeve when using circulation lubrication method, main shaft bearing oil use for a long time and the same, will not produce for swimming and clogging oil mud and the bearing clearance, reduce corrosion, so the oil has good resistance to oxidation stability, China's industry standard oil oxidation stability index for 1000 h ( ( GB / T, 12581) 。 4, suitable strength and good temperature characteristics to machine the main uranium for use temperature is not too high and make the machine tool thermal deformation, affect the machining accuracy or make poor lubrication bearing, should according to the structure of the spindle bearing, speed and bearing clearance to choose suitable doneness of lubricating oil Wells for oil has good temperature characteristics show concern and prevent a spindle working temperature and environmental temperature change is big, the change in temperature which influence the lubrication performance. Bearing is a kind of important modern machinery and equipment parts. Its main function is to support the mechanical rotator, reduce the coefficient of friction in the process of its movement ( frictioncoefficient) And ensure that the rotation accuracy. Bearing need to keep the lubrication under high-speed operation, is suitable for grease lubrication in time so as to ensure the normal operation of our machines, at the same time, it can prolong the service life of main shaft bearing.
