Choosing the right bearing: The correct type must be used for each application including proper mounting and lubrication

摘要

Rotating shafts are used in many types of equipment in feed mills. This can vary from a simple hand wheel shaft to open or close a gate, to high speed shafts turning pulleys or blades in a piece of equipment. No matter the purpose of the shaft, it hasto be supported with some type of bearing. These bearings vary from a simple plain sleeve-type bearing to a precision ball or roller bearing. Bearings are subjected to two forces or a combination of these forces. The first force is radial based on the forces that act perpendicular to the shaft. Examples of these are forces needed to hold a shaft in place from forces pulling perpendicular to the shaft. Keeping the hand wheel shaft in a fixed location while it is used to move the slide in a gate is one example. Another is to support the headshaft and pulley on a bucket elevator or conveyor.
