The stop collar according to its use function,professionals suggest that the rolling bearing is fixed on the shaft and bearing seat in the radial,axial and circumferential direction accordingly.Radial and circumferential positioning is usually achieved by friction,that is,the bearing ring is tightly matched.And the axial positioning is often achieved by direct contact,for example:with nuts,bearing seat end cover,shaft end stop stop ring,sleeve and clasp,etc
The matching of bearing mounting parts
The fit is specified on the basis that the tolerances of the shaft and bearing pedestal are in accordance with ISO and the tolerances of the bearing inner diameter and bearing outer diameter are in accordance with DIN 620.ISO tolerances are indicated in tolerance bands.The tolerance has two characteristics,namely its position relative to the zero line and its width.Tolerance positions are indicated by letters.
The following problems should be paid attention to when selecting the matching tolerance of bearings:
In order to make full use of bearings and bearing capacity,it is necessary to make the inner and outer rings of bearings well circumferentially supported.
There shall be no relative movement between the bearing sleeve and its matching parts,otherwise it will damage the matching surface.
One of the inner and outer rings of the traveling bearing must be able to adapt to the change of the length of the shaft and the box,that is,it can move axially.Only N and NU type cylindrical roller bearings can be moved internally.
