Deep groove ball bearings (GB / T 276-2003) The list of radial ball bearings is the most widely used rolling bearing. It is characterized by low frictional resistance and high speed. It can be used for mechanical parts that can bear radial load or combined load of radial and axial simultaneously. It can also be used for mechanical parts that bear axial load, such as small power motors, Automotive and ctor gearboxes, hine tooearboxes, general hines, tools, etc.Basic sThe basic deep groove ball bearing is composed of an outer ring, an inner ring, a group of steel balls and a group of retaining frames. There are two types of deep groove ball bearings: single row and double row. The deep groove ball structure is also divided into two types: sealed and open. The open type refers to the bearing without a seal structure. The sealed deep groove ball is divided into dust seal and oil proof seal. The material of the dustproof sealing cover is stamped from steel plate, which only serves to simply prevent dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent the grease in the bearing from overflowing.Bearing structureThe deep groove ball bearing has a simple structure and is easy to achieve higher manufacturing accuracy than other types, so it is convenient for ma production in a series, the manufacturing cost is also low, and it is extremely popular. In addition to the basic type, deep groove ball bearings also have various modified structures, such as: deep groove ball bearings with dust covers, deep groove ball bearings with rubber seals, deep groove ball bearings with stop grooves, Deep groove ball bearing with large load capacity of ball notch, double row deep groove ball bearing.ApplicationDeep groove ball bearings can be used in gearboxes, instruments, motors, household appliances, internal combustion engines, nsportation vehicles, agritural hinery, construction hinery, construction hinery, roller skates, yo-yo, etc.Clearance:The radial clearance of the bearing is p>
