And positioned at the seal section outside, it is described clamping section be mutually perpendicular to seal section, the inner surface of the seal section with it is described
The sealing surface of bearing outer ring is in sealing contact, and the clamping section is engaged by clamping with the card access surface on the bearing outer ring.
In a preferred embodiment of the invention, the seal section on the modified form dustproof cover is dashed forward to close to steel ball direction
Go out, the clamping section is turned down to away from steel ball direction.
Since the dustproof cover of the present invention is made of cold-rolled steel sheet, in the case of proof strength, its thickness is with respect to rubber
Manufactured dustproof cover thickness can be greatly reduced, so as to expand bearing interior space so that special micro- bearing is in appearance and size
In the case of constant, by increasing the diameter of steel ball, to improve its radial direction bearing capacity and axial bearing capacity, and extend at the same time special micro-
The service life of bearing.The modified form dustproof cover also allows for installing at the same time.
In a preferred embodiment of the invention, can also be by increasing the outer ring channel footpath on bearing outer ring and reducing axis
The inner ring ditch footpath on inner ring is held further to increase bearing interior space, so as to further increase the diameter of steel ball.
In a preferred embodiment of the invention, the retainer is molded using cold-rolling steel-plate punch, further to prolong
The service life of long special micro- bearing.
