Deep groove ball bearing

Deep groove ball bearings are 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 bearings: single row and double row. The deep groove ball structure is also divided into sealed and open structures, which mainly bear radial loads and can also bear a certain amount of axial loads. When it only bears radial loads, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can withstand large axial loads. The friction coefficient of deep groove ball bearings is very small and the ultimate speed is also high.

Deep groove ball bearings have a wide range of applications, suitable for high-speed or even extremely high speed operation, and are very durable without frequent maintenance. They are widely used in industries such as precision instruments, low-noise motors, automobiles, motorcycles, and general machinery.
