Circle, rolling element, retainer and skeleton contact seal are equipped with retainer, peace in retainer between the outer ring and inner ring
Equipped with rolling element, the both ends of outer ring external cylindrical surface are symmetrically arranged with the step cutting pattern of recess, and the radial direction of roots level is provided with
For fixing the annular groove of skeleton contact seal, skeleton contact seal one end is fixed on the step of outer ring external cylindrical surface
On, the other end is contacted with inner ring raceway or inner-ring small flange；The skeleton contact seal is by skeleton and is connected on skeleton
Sealing lip constitute, the skeleton be cross section be in " 7 " font ring structure, the lower end of " 7 " font is fixedly connected with
Sealing lip, sealing lip are contacted with inner ring raceway or inner-ring small flange, the inside bending in head of " 7 " font upper end, with outer ring step
On annular groove match.
The width that the width of the outer ring is equal to inner ring subtracts twice of skeleton wall thickness.
The thickness that described its radial depth of the step cutting pattern at outer ring external cylindrical surface both ends is less than or equal to outer ring subtracts skeleton
Wall thickness, axial depth are equal to " 7 " font cross-sectional width of skeleton.
On the outer ring external cylindrical surface both ends step for fix the annular groove of skeleton contact seal with outer ring outside
The center cross-sectional on cylindrical surface is symmetrical plane, and it is symmetrical to constitute plane.
Its bottom surface of the annular groove is inclined-plane.
The beneficial effects of the utility model are: the bearing capacity and aligning performance of bearing are not influenced by sealing station, and
And bearing seal assembly is simple, not will cause the early stage improper failure of sealing in transport and installation process；Bearing working process
In, skeleton contact seal is compressed by other parts and cycle surface, ensure that the normal work of sealing, to improve close
The service life of envelope and bearing.
