Deep groove ball bearing

Deep groove ball is a common type of rolling bearing. The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. 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 means that the bearing does not have a sealed structure. The sealed deep groove ball is divided into dust-proof seal and oil-proof. Sealing, the dustproof sealing cover is made of steel stamping, which can 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.

Single row deep groove ball bearing type code is 6, double row deep groove ball bearing code is 4. It has a simple structure and is easy to use. It is a kind of bearing that is widely produced and widely used. The deep groove ball bearing mainly bears radial load, and can also bear radial load and axial load at the same time. When it is only subjected to radial load, 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 bear a large axial load. The friction coefficient of the deep groove ball bearing is very small, and the limit speed is also high.

Compared with other types, the deep groove ball bearing has a simple structure and is easy to achieve higher manufacturing accuracy, so it is convenient for mass production in series, and the manufacturing cost is also low, and it is extremely common. In addition to the basic type, deep groove ball bearings also have various modified structures, such as: deep groove ball bearings with dust cover, deep groove ball bearings with rubber seals, deep groove ball bearings with retaining grooves, and Deep groove ball bearings with large load capacity of ball notches, double row deep groove ball bearings.

Deep groove ball bearings are representative rolling bearings, which are widely used, suitable for high-speed or even extremely high-speed operation, and are very durable and do not require frequent maintenance. This type of bearing has small friction coefficient, high limit speed, low manufacturing cost and easy to achieve high manufacturing precision. The size range and form vary, and are used in precision instruments, low-noise motors, automobiles, motorcycles and general machinery and other industries. It is a widely used type of bearing in the machinery industry.
