High standard 6200 ball bearing

The friction pair and the working environment (humidity) should be considered. Under normal circumstances, if the transfer speed of grease is increased by 2000r/min, its life will be reduced by about half.1. When adding grease, squeeze out the waste grease until you see new grease at the grease outlet. (3) The selected grease should be compatible with the load. At high speeds, a grease with a large penetration degree made of low-viscosity base oil should be selected; for low-speed grease, you should choose Grease with high penetration grade made of high viscosity base oil. 3 grease should be used. It is an important factor affecting the service life of grease. Main performance indicators of grease ①Drop point: refers to the temperature at which a certain fluidity is reached when heated under specified conditions. In the environment of strong chemical medium, synthetic oil grease resistant to chemical medium such as fluorocarbon grease should be selected. (7) Do not use wooden or paper containers to package grease to prevent oil loss and hardening, mixing with moisture, or being contaminated and deteriorated, and should be stored in a cool and dry place. Remove waste grease and clean the parts. In this way, the variety of grease is reduced, the management of grease is simplified, and the cost of grease can be reduced due to the long service life of pleiotropic grease, and maintenance costs can be reduced. When the use temperature is high, the grease with good oxidation resistance, low evaporation loss and high dropping point should be selected; when the use temperature is low, it should be selected Grease with low starting torque and similar viscosity, such as grease based on synthetic oil. , Cone penetration is reduced and hardened, after a certain 69 Series Ball Bearings, the grease will completely fail; under the action of mechanical shear, the structure of the grease will be destroyed (such as soap fiber detachment or orientation), causing its softening,69 Series Ball Bearings ...ادامه مطلب
