Bearing seal
Bearing seal in the form of the structure of contact type and non-contact seal. According to the contact form can be divided into radial sealing and axial seal. According to the structure of the sealing ring can be divided into single lip seal and double lip seal. Non-contact seal generally has two kinds of dust cover and rubber seal. Dust cover seal gap is big, only suitable for dustproof, rubber sealing ring seal clearance is small, has good sealing effect. Contact sealed bearing usually only rubber seal auxiliary parts. Rubber seal lip is certain to stick together in contact with the bearing rotating parts interference, which has good dust seal effect, its limit rotational speed is low and friction torque is bigger.
