Types of Bearings | Uses & Working Mechanisms Explained

25/8/2020· Fluid bearings are used in machines that work at high speeds and loads. While the initial costs are higher, the longer lifespan in tough conditions makes up for it in the longer run. When the machine is running, there is zero contact between the two elements (except during the start and stop) and hence it is possible to achieve near zero wear with fluid bearings.
