Maintenance and care of bearings

Dismantling of bearings is carried out for regular maintenance and bearing replacement. After disassembly, if the bearings continue to be used, or if it is necessary to check the status of the bearings, the disassembly should be carried out with the same care as when they are installed. Be careful not to damage the bearing parts, especially the disassembly of interference fit bearings, which are difficult to operate.

Bearing life standard

The number of revolutions or hours that a bearing experiences before pitting occurs under a certain load is called the bearing life.

The origin of the development of bearings

An early form of linear motion bearing was a row of wooden rods placed under a row of skids. Modern linear motion bearings use the same principle of operation, except that sometimes balls are used instead of rollers.

Features of spherical plain bearings

The structure of the spherical plain bearing is simpler than that of the rolling bearing, which is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. Joint bearings are generally used for low-speed swinging motion (ie angular motion). Since the sliding surface is spherical, it can also perform tilting motion (ie self-aligning motion) within a certain angle range. When the degree is large, it can still work normally.

How deep groove ball bearings work

Deep groove ball bearings mainly bear radial load, and can also bear radial load and axial load at the same time. When it is only subjected to radial load, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can bear a large axial load. The friction coefficient of the deep groove ball bearing is very small, and the limit speed is also high.
