What are the characteristics of deep groove ball bearings?

Edit: Rihoo Industry (Hongkong) Co.,Limited    Date: May 31, 2018

Deep groove ball bearing inner and outer races are arc-shaped deep groove, the channel radius is slightly larger than the ball radius. It is mainly used to bear radial loads, but it can also withstand certain axial loads. When the radial clearance of the bearing is increased, it has the function of an angular contact ball bearing, can withstand a large axial load, and is suitable for high-speed rotation. When the bearing is tilted relative to the housing hole and shaft by 8' to 16', the bearing can still work normally, but its service life is affected. This type of bearing can withstand pure axial loads when the rotational speed is high and thrust ball bearings are not suitable.

Deep groove ball bearings generally use a two-part synthetic steel punched cage, but large-size or high-speed bearings use solid cages. Such cages are guided by balls like punched cages, and high-speed deep groove ball bearings are maintained. Racks are usually guided by inner or outer ribs.

Compared with other types of bearings with the same size, deep groove ball bearings have a low coefficient of friction, low vibration and noise, high speed limit, and high precision. They are the preferred bearing types for user selection. However, this type of bearing is not resistant to impact and does not adapt to withstand heavier loads.

Deep groove ball bearing is simple in structure and easy to use. It is the largest production batch and the most widely used type of bearing. Widely used in automobiles, home appliances, machine tools, motors, pumps, agricultural machinery, textile machinery and many other fields. Its output accounts for more than 70% of the total output of bearings, and it is the type of bearing with the highest output in China, the most commonly used and the cheapest.
