10 Pcs 6903-2RS 17x30x7mm ABEC-7 Deep Groove Ball Bearings, Rubber Sealed for Bicycle Hubs

FUZHGYEAL

Ideal for machinery assembly, equipment repair, shelving, conveyor systems, and structural mounting. Fits bicycle front and rear hubs, wheel axles, and rotating assemblies requiring a 6903 bearing with 17mm bore and 30mm outer diameter. Steel rings and balls with ABEC-7 tolerance deliver smooth rotation and resist wear under typical riding loads and varied terrain conditions. Rubber seals on both sides retain grease and block dirt and moisture, helping the bearing run clean through wet and dusty trail or road use. Blue seal design provides a quick visual identifier during hub service; deep groove geometry handles combined radial and axial wheel loads. 10-piece set covers multiple hub rebuilds or wheel replacements; press directly into hub shells using standard bearing installation tools., Manufacturer: FUZHGYEAL
