Overview of deep groove ball bearings

wallpapers News 2021-08-10
Deep groove ball bearings are originally listed as radial ball bearings, and they are the most widely used rolling bearing. It is characterized by low frictional resistance and high speed. It can be used on parts that bear radial load or a combined load that acts on both radial and axial directions. It can also be used on parts that bear axial load, such as low-power motors, Automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.
A brief introduction about ball bearings
Ball bearings are mainly composed of four basic elements: balls, inner ring, outer ring and retainer. The general industrial ball bearings meet the standards. The balls and rings are usually made of high chromium steel, and the Rockwell hardness is between 61~65. The hardness of the retainer is lower than that of the ball and ring, and its materials are metal (such as medium carbon steel, aluminum alloy) or non-metal (such as Teflon, PTFE, polymer materials). Ball bearings have lower rotational frictional resistance than journal bearings, so at the same speed, the temperature generated by friction will be lower.
Basic parameters
Deep groove ball bearings are the most common type of rolling bearings.
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 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 and oil-proof seal. The dust-proof seal cover material is stamped with steel plate, which only serves to 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.
The single row deep groove ball bearing type code is 6, and the double row deep groove ball bearing type code is 4. Its simple structure and convenient use make it the most commonly produced and widely used type of bearing.
