VC Type Oil Seal is single lip without spring and rubber covered rotary seal. The design of the external rubber, widely used in the assembly environment of various materials, can be applied to soft alloy or plastic deformation of boring, boring in the damage of the surface can also be used.
Generally applicable to pressure-free environments, especially for oil or high viscosity liquid conditions.
Characteristic: Lip ring with spiral spring for radial preloading.
Cut sealing edge for high dynamic sealing effect.
Metallic interference fit at the groove bottom diameter. Compared with the fully rubber-covered VA shaft seal ring, this results in higher protection from the seal being pressed out of the groove.
Range of application:
Primarily for sealing oil- and grease-lubricated shaft ducts with very little or no exposure to external(ambient) dirt.
