Description
Wheels are built according to an execution, which resembles serie 62 ball bearings’. Yet wheels are provided with a higher outer ring. Wheels with two rows are thought to resist bi-directional axial forces. This can be achieved thanks to the higher number of balls. These series present a C3 radial play. The series with outer cylindrical ring are built according to DIN rules and present a PN tolerance class: while, the series with outer spherical ring have D diameter tolerance (-0.05). The radial play is CN and lubrication is made by means of some lithium’s soap grease. Suffix – U indicates the spherical external ring. To use bearings as wheels, coefficients Cw and Cow must be taken into consideration. The latter are calculated on the basis of the elastic deformation of the bearing’s outer ring, when the object itself is bearing a load.
