Description
Technical field
The utility model relates to a kind of bearing that carries sealing.
Background technique
General bearing enclose width equates, be arranged on the bearing of axle head owing to being provided with the axially movable axle jump ring of restriction bearing at axle head, cause axle head axially exceeding bearing, in some occasion, can affect the design and installation of other component, the life-span of the existing bearing seal that carries sealing is also undesirable.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, a kind of stuffing box bearing is provided.
The utility model solves the technological scheme that its technical problem adopts: a kind of bearing that carries sealing, comprise bearing outer ring and bearing inner race, between described bearing inner race and bearing outer ring, be provided with steel ball and retainer, the axial dimension of described bearing inner race is at least less than the axial dimension 3mm of bearing outer ring; Described bearing outer ring has step hole, and the macropore that step hole comprises aperture and minute is located at aperture two ends, offers annular steel ball rolling channel on aperture hole wall, and the step place of macropore and aperture offers annular groove; Between described bearing outer ring and bearing inner race, be provided with a pair of annular sealing cover that lays respectively at steel ball both sides, annular sealing cover comprises ring-shaped rubber part and ring skeleton, ring skeleton is sleeved on ring-shaped rubber part and is bonding with it, the inner side of described ring-shaped rubber part has the lip that contacts of three circles and bearing inner race outer side surface close contact, and the circumferential outer of ring skeleton is provided with the bending part of embedded rings connected in star.
The beneficial effects of the utility model are: the utility model be arranged on axle head with axle with jump ring fixedly time, the free end that axle head stretches out bearing inner race can not exceed the outer ring of bearing, has solved the problem proposing in background technique; Ring-shaped rubber part of the present utility model has the lip that contacts of three circles and bearing inner race outer side surface close contact, and sealing life is relatively long, and sealing effect is also better.
