Characteristics of Deep Groove Ball Bearings


Deep groove ball bearings, a subtype of bearings, are widely used due to their extensive applications and long service life. They are broadly applied in modern equipment manufacturing industries, significantly enhancing the processing accuracy and quality of equipment installations. It can be said that deep groove ball bearings will be extensively used in future equipment installations, and their market prospects are promising.  


Overview of Deep Groove Ball Bearings


Deep groove ball bearings generally consist of a pair of rings, a set of cages, a set of rigid balls, and a set of cages. The type code for deep groove ball bearings is 6, which is the most commonly produced and widely used type of bearing. Deep groove ball bearings have simple structures, are easy to use, and are produced in large volumes, capable of bearing certain axial loads. When the radial clearance of the bearing increases, it functions as an angular contact ball bearing, capable of bearing larger axial loads.


Deep groove ball bearings are mainly used to bear pure radial loads but can also simultaneously bear radial and axial loads. When bearing only pure radial loads, the contact angle is zero. When deep groove ball bearings have larger radial clearances, they exhibit the properties of angular contact bearings and can bear larger axial loads. The friction coefficient of deep groove ball bearings is very small, and their critical speed is also very high. Especially under high-speed operating conditions with significant axial loads, deep groove ball bearings are superior to thrust ball bearings. 


Compared to other types of bearings of the same size, these bearings have a smaller friction coefficient and higher critical speed. In cases where thrust ball bearings are not suitable due to high speeds, these bearings can be used to bear axial loads. After mounting on a shaft, these bearings can limit the axial displacement of the shaft or housing within the axial clearance range of the bearing. Additionally, when there is a relative tilt between the housing hole and the shaft (or the outer ring relative to the inner ring), these bearings can still function normally (within the range of 8-16 according to the clearance). However, the existence of such a tilt will inevitably reduce the bearing's service life.


Compared with other bearing types of the same size, deep groove ball bearings have the least friction loss and higher critical speed. They can be used to bear pure axial loads in situations where thrust ball bearings are not suitable due to high speeds. If the manufacturing accuracy is improved and solid cages made of bakelite, bronze, or hard aluminum are used, their speed can be further increased.


Characteristics of Deep Groove Ball Bearings


Deep groove ball bearings have simple structures and can achieve higher manufacturing precision compared to other types, making them suitable for serial mass production at lower manufacturing costs, leading to widespread use. When larger radial clearances are selected, the axial load-bearing capacity increases, and when bearing pure radial loads, the contact angle is zero. When axial forces are applied, the contact angle is greater than zero. Typically, wave-shaped cages are used, with machined solid cages for inner diameters larger than 200mm or high-speed bearings. They all share the following common characteristics:


  • Structurally, each ring of the deep groove ball bearing has a continuous groove-shaped raceway approximately one-third of the ball's circumference in cross-section. It is mainly used to bear radial loads but can also bear certain axial loads.


  • When the radial clearance of the bearing increases, it behaves like an angular contact ball bearing and can bear bidirectional alternating axial loads;


  • Low friction and high speed;


  • Simple structure, low manufacturing cost, and easily achievable high manufacturing precision;


  • Typically, wave-shaped cages are used, with solid machined cages for inner diameters greater than 200mm or high-speed bearings.
