Deep groove ball bearing

Deep groove ball is a common type of rolling bearing. The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls, and a set of retaining structures. There are two types of deep groove ball bearings: single row and double row. The deep groove ball structure is also divided into sealed and open types. Open type refers to bearings without a sealed structure, while sealed deep groove balls are divided into dust-proof and oil proof seals. The dustproof sealing cover material is stamped steel plate, which only plays a simple role in preventing dust from entering the bearing raceway. The oil proof type is a contact type oil seal, which can effectively prevent the lubricating grease inside the bearing from overflowing.

The type code for single row deep groove ball bearings is 6, and the code for double row deep groove ball bearings is 4. Its structure is simple and easy to use, making it a widely produced and applied type of bearing. Deep groove ball bearings mainly bear radial loads, and can also bear both radial and axial loads simultaneously. When it only bears radial loads, the contact angle is zero. When deep groove ball bearings have a large radial clearance, they have the performance of angular contact bearings and can withstand large axial loads. The friction coefficient of deep groove ball bearings is very small and the maximum speed is also high.
Deep groove ball bearings have a simple structure and are easier to achieve higher manufacturing accuracy compared to other types, making them convenient for mass production in series and with lower manufacturing costs. They are widely used. 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 bearings with large load capacity and ball mounting gaps, and double row deep groove ball bearings.
