Type C Oil seal

Built up Seals or type 'C' Oil seal:

Type 'C' oil seal has an additional cup inserted into the outer cup of 'B' type. The supplementary metal inner ring provides a superior stiffness. This type is recommended for use in heavy polluted environments. As the static sealing between housing and metallic shell is limited, low viscosity media can "creep".
- Very good fitting stability avoiding pop-out of the seal
- Modern lip design provides low radial forces
- Superior radial stiffness, especially for very large diameters
- Cost effective for expensive elastomer materials
- Suitable for use in combination with axial seal
