Deep groove ball bearings are one of the most common types of rolling bearings.
Basic deep groove ball bearings consist of an outer ring, an inner ring, a set of steel balls and a set of holding frames. Deep groove ball bearing types have single row and double row two, deep groove ball structure is also divided into sealed and open two structures, open type means that the bearing does not have a sealed structure, sealed deep groove ball is divided into dust seal and oil seal. The dust-proof sealing cover material is stamped from steel, which simply prevents dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent grease spillage in the bearing.
Single row deep groove ball bearings have type designation 6 and double row deep groove ball bearings have code 4. Its structure is simple, easy to use, and it is the most common and widely used type of bearing.
