In fact, deep groove ball bearings have another academic name, single row radial ball bearings. Its English name Deep groove ball bearing, literal translation is deep groove ball bearings, which is why it is called deep groove ball bearings. Of course, there is another reason, which is the structure of deep groove ball bearings, which is obvious in the picture below. An outer ring, an inner ring, and a deep groove in the middle are lined with rolling steel balls, so they are very vividly called deep groove ball bearings.
In fact, there is a more evocative meaning, the lubricated ball can only be seen with deep grooves. Therefore, this bearing does not live up to this meaning, and is accepted and loved by the majority of manufacturing industries.
As far as the classification of bearings is concerned, deep groove ball bearings are the most typical structural form of rolling bearings. Their friction torque is small, and they are most suitable for environments requiring high speed, low noise, and low vibration, etc., and have a wide range of uses.
1. The grooves on the inner and outer rings have an arc-shaped interface with a radius slightly larger than that of the ball. Mainly can bear radial load.
2. In addition to the open type, this kind of bearing also has a bearing with a steel plate dust cover, a bearing with a contact rubber seal ring, a bearing with a non-contact rubber seal ring, or a bearing with a stop ring on the outer diameter of the outer ring .
3. The ball bearing with dust cover or sealing ring is sealed with a proper amount of high-quality lubricating grease. Deep groove ball bearings generally use steel stamping cages, which have small frictional moments and an accuracy grade of 0.
