Ball bearing are found in practically any type or
size of motor. They offer low friction, can oprating at high speed and run
effectively over a wide temperature range. Modern ball bearing are well
designed for the job at hand, are made of increasingly better materials, and
last longer. Show the basic parts of a rolling – type bearing.
In the ball
bearing family the most popular assembly is the single – row deep – groove
bearing
It is a
radial load bearing, but it can also handle considerable thrust loads in either
axial direction. ( A thrust load is a pushing force against the bearing
parallel to the shaft ; radial loads is a pressing force at right angles to the shaft. Most bearings are
expected to carry both type of loads to some degree )
