How Cylindrical roller bearing should choose ?

Means a radial clearance of the rolling bearing of a stationary collar and another collar in the direction perpendicular to the bearing axis , from one extreme position to another extreme position of the movement amount
tapered roller bearings structural features Means a radial clearance of the rolling bearing of a stationary collar and another collar in the direction perpendicular to the bearing axis , from one extreme position to another extreme position of the movement amount . Select the correct bearing clearance or not, precision mechanical operation , bearing life , friction , temperature , vibration and noise , etc. have a great impact. Such as radial bearing clearance selection is too small, will cause the body to withstand an increase in the number of load rolling contact sendzimir mill bearings stress decreases, more stable operation , however , friction will increase, temperature will increase. On the contrary , it increases contact stress , vibration , and reduced frictional resistance , low temperature . Accordingly, bearing conditions, to choose the most appropriate clearance values ​​, has very important significance.

In fact when the election bearing clearance must fully consider the following several major factors:

( 1 ) bearing and shaft and housing bore with the tightness will lead to changes in the bearing clearance values. After the general bearing clearance will reduce the value of the installation ;
