Structures of rolling bearings and plain bearings Antifriction bearings support the rotation of rotating drum shafts, so the contact position is one point, rolling more contact points nine more; the difference between the first appearance sleeve bearings support the rotation of the shaft, The surface is smooth, so it touches part of the surface. In different ways, followed by kinematic, kinematic rolling roller bearings; the case of sliding motion sliding and friction is completely different.
Rolling bearings are used in smaller machines, at high speeds, such as motors, gearboxes, etc., under low-speed, heavy-load conditions of slip-down conditions, general applications or lubrication and functional components, maintenance difficulties such as propulsion shafts.
