Bearing clearance means the value of displacement of the unfixed ring when it moves against the fixed ring in radial or axial direction before the bearing is mouted on a shaft or in a housing. According to the movement direction, it falls into radial clearance and axial clearance.
In accoedance with the standard of ISO05753,The radial Clearance can be divided into five groups. Radial Clearance Value without load See Table 5
