Premium Quality Bearings: High-speed bearings feature low-draw, double-lip seals that provide superior exclusion of moisture and dirt, improving grease retention.
Type TC [Twin Lip] Seals: Nitrile elastomer wheel seals are specifically designed to keep out water and dirt.
Optimal Sealing: Rubber-coated outside diameter creates an optimum seal at the hub; steel garter spring guarantees constant pressure on the axle shaft.
