SELECTIVE OUTLINE OF BEARINGS
There are various types of bearings with different sizes. To meet the designed purposes, it is
necessary to select correct bearings according to the combined analysis result among the practical
factors such as the mechanical conditions, the technical requirements , the space data around the
bearings and market and economic considerations.
Due to the fact that the bearings are selected as per the decided bearing diameters , the first
factor is to check the fitting space and the way for fitting on the basis of the inner diameter of
the bearings before looking for the special type of bearings.
Secondly, it should be necessary to compare the bearing lives and then determine the size of
the bearings according to the results of calculation of bearing life under loads.
Lastly , it is helpful to consider the inner specs of the bearings such as the accuracy grades,
inner clearance, retainer, lubrications etc.
Fig 4 shows general procedures for bearing selection and the conditions that should be considered
in application. Though these are not compulsory , they will help to satisfy the most important
technical requirements.
