The internal clearance of the ball NMB bearing will have a serious impact on the function of bearing, oscillation, sound, heat and other bearings.
Therefore, it is very important to choose the appropriate internal clearance according to the use.
The clearance can be divided into three kinds of clearance: radial clearance, axial clearance and angular clearance.
Radial clearance (Gr) Radial clearance is the amount of movement that causes the outer ring to move in the radial direction when the inner ring is fixed.
Axial clearance (Gt) Axial clearance is the amount of movement that occurs when the inner ring is fixed and the outer ring moves in the direction of the shaft.
Angular clearance (θ) An angular clearance is the amount of movement that occurs when the outer ring is tilted toward the axis when the inner ring is fixed.
