Deep groove ball bearings are the most common type of rolling bearings. 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 the most commonly produced and widely used type of bearing.
1、 The working principle of deep groove ball bearings:
Deep groove ball bearings mainly bear radial loads. 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.
2、 Characteristics of deep groove ball bearings:
Deep groove ball bearings are the most representative rolling bearings with a wide range of applications. Suitable for high-speed or even extremely high speed operation, and very durable, requiring no frequent maintenance. This type of bearing has a low friction coefficient, high maximum speed, simple structure, low manufacturing cost, and is easy to achieve high manufacturing accuracy. Its size range and form variations are diverse, and it is applied in industries such as precision instruments, low-noise motors, automobiles, motorcycles, and general machinery.
After being installed on the shaft, deep groove ball bearings can limit the axial displacement of the shaft or housing in both directions within the axial clearance range of the bearing, thus enabling axial positioning in both directions. This type of bearing also has a certain degree of self-aligning ability, and can still work normally when tilted 2 'to 10' relative to the housing hole, but it has a certain impact on the bearing life.
Deep groove ball bearings are mainly used to withstand radial loads, but when the radial clearance of the bearing is increased, they have a certain degree of angular contact ball bearing performance and can withstand combined radial and axial loads. When the speed is high and thrust ball bearings are not suitable, they can also be used to withstand pure axial loads
3、 Application of Shandong Baishi Bearing Deep Groove Ball Bearing:
Deep groove ball bearings can be used in gearboxes, instruments, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, engineering machinery, roller skates, yo yo, and more.
