The term clearance in a bearing is defined as the distance that its components can move relative to each other.
Depending on the type of bearing, the internal clearance of the bearing can be defined in two variants, radial and axial, depending on its direction with respect to the axis.
In Bikone’s Asymetric PreSet Hubs we use the double row angular contact bearing configuration, with greater precision than the rest of the design, although it requires strict control of the axial clearance to optimize the distribution of the contact pressure according to your power or weight. The axial clearance is measured in microns of millimeter and only with the best technology in automatic processes can it be controlled. Improper configuration can result in overpressure, increased temperature and premature bearing failure.
