Advantages and disadvantages analysis of air bearing

Bearings may be classified according to the using performance or shape etc, and the classification of the air bearing is relatively less, according to the working principle of the use of air bearing, can understand the air bearing in use process will reflect the advantages and disadvantages of the following: & emsp;   Air bearing main advantages: & emsp;   1, friction small, movement is very smooth and no crawling phenomenon;     2, high precision movement;     3, high speed;     4, the kinematic viscosity is extremely low, air system basic without fever phenomenon;     5, can be used in a wide temperature range ( Except for porous) ;     6, on the environment pollution-free.     Air bearing main drawback: & emsp;   1, low carrying capacity;     2, low stiffness;     3, poor damping;     4, the air dynamic pressure bearing cannot work under low speed condition, and can produce mechanical wear during start and stop;     5, high requirement of aerostatic bearing should be equipped with air supply system. 【 Warm prompt. 【 The bearing network] Some information from the Internet, and strive to secure timely, accurate, aims to deliver more information, does not represent our views to its approval or responsibility for their authenticity.
