Group mounting hole specification is identical, and the link is equipped with two groups, and two groups of link specifications are identical, and the tension spring is equipped with two groups, and two groups
Tension spring specification is identical.
The utility model has the beneficial effects that one kind of the utility model is used for automotive hub single-wheel bearing, because this is practical new
Type is added to dustproof cover, link, tension spring and seal groove, which prevents extraneous dust from entering inside automobile hub bearing, subtracts
The abrasion for having lacked automobile hub bearing solves the problems, such as that original automotive hub single-wheel bearing sealing effect is bad, improves this
The service life of utility model.
Because outer ring is connected by welding with bearing, which increases the fastness that outer ring is connect with bearing, because of lubrication
Intracavitary portion be equipped with arc groove, the design can steel ball carry out maintenance, falling off for steel ball is avoided, because of dustproof cover and seal groove phase
Match, which increases the leakproofness of automobile hub bearing, and the utility model is structurally reasonable, and sealing effect is good, and it is not easy to wear, make
It is long with the service life.
