The structure of rolling bearings and sliding bearings Anti-friction bearings support the rotation of the rotating drum shaft, so the contact position is one point, rolling more contact points nine more; the difference between the first appearance of sleeve bearings supports the rotation of the shaft The surface is smooth, so it touches part of the surface. In different ways, followed by motion, motion rolling roller bearings; sliding motion sliding and friction situation 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 sliding conditions, general applications or lubrication and functional parts, and difficult maintenance such as propulsion shafts.
