Features: * The bearings use durable steel as the material, which can reduce abnormal noise, housing vibration and keep driving safety with regular replacement. * High-quality high-speed bearings have low resistance, double-lip seals on both sides, which provides excellent water and dirt exclusion and improved grease retention. * High-performance grease contains special rust inhibitors for the most demanding applications. * TC type wheel seals, nitrile elastomer, are specially designed to resist water and dirt. Rubber coated outer diameter creates an optimal seal on the hub.
