Should be formed with the matched interior rollaway nest of steel ball, be correspondingly formed between the up/down steps face of outer ring with the matched outer rollaway nest of steel ball,
Such structure setting not only causes the structure of bearing is simpler to gather, but also inside and outside circle can also form positioning to steel ball and be pressed against, and have
Help better stationary positioned steel ball.
The utility model can be further arranged to this end that the V-arrangement bending part is resisted against on outer ring inner ring face and be additionally provided with
Along the outer ring inner ring face extension that axially fitting extends, and location structure is additionally provided between the extension and outer ring inner ring face.
It is set by above structure, it not only can preferably stationary positioned skeleton, but also make to be formed between skeleton and outer ring even closer
Fitting, contribute to further lift-off seal effect.
It is to form to be mutually inserted the convex block of positioning and recessed that the utility model, which may further be provided as the location structure,
Slot, the convex block integrated molding are arranged on the extension, and the groove is opened on outer ring inner ring face.
It is preferably compressed spring that the utility model, which may further be provided as the elastic component, naturally it is also possible to be shrapnel
Etc. other structures, the pillar of positioning compressed spring is provided on the inside of the both ends of V-arrangement bending part.
The utility model may further be provided on the outer ring surface for the inner ring correspond to sealing ring axially inner side also
It is provided with the bulge loop axially abutted with sealing ring composition.By setting bulge loop, axially position not only is formed to the installation of sealing ring,
And it also can effectively prevent inner ring in use and axial float occur.
