The characteristics of jiaxing bearing/air bearing

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. 1, low friction due to gas was much lower than the liquid viscosity, viscosity of air at room temperature is only one over five thousand of the number 10 machine oil, and the bearing friction is proportional to the viscosity, so the gas bearing friction is lower than liquid lubricated bearing. 2, wide speed range of gas bearing friction is low, low temperature, the speed of up to 50000 RPM, the temperature rise not to exceed 20 ~ 30 ℃, speed is even up to 1. 3 million RPM. Aerostatic bearing can also used for low speed, even zero speed. 3, suitable temperature range gas can in great temperature range gas, its viscosity is influenced by temperature is small ( Viscosity at higher temperatures also increases slightly, such as temperature from 20 ℃ to 100 ℃, and the air viscosity increased by 23%) And, therefore, the application of the gas bearing temperature range can be up to - 265 ℃ to 1650 ℃. 4, low carrying capacity of dynamic pressure bearing capacity is proportional to the viscosity, the bearing capacity of gas dynamic pressure bearing only same size liquid dynamic pressure bearing a few parts per thousand. Due to the compressibility of the gas, gas dynamic pressure bearing capacity limit value, average unit load can only be added to the projection area 0. 36 million mpa. More than 5, the machining accuracy requirement tall if you jiaxing bearing group co. , LTD.
