Deep groove ball bearing, why is it called deep groove ball

Deep groove ball bearings are one of our most common types of bearings, and are widely used in production and life.

In fact, deep groove ball bearings have another academic name, single row radial ball bearings. Its English name Deep groove ball bearing, literally translated, is a deep groove ball bearing, which is why it is called a deep groove ball bearing. Of course, there is another reason, which is the structure of the deep groove ball bearing, 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 fragrant meaning, only deep grooves can see lubricating balls. 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. They have low friction torque and are most suitable for environments requiring high speed, low noise, and low vibration. They are widely used.

Features

1. The channel on the inner and outer rings has an arc-shaped interface radius slightly larger than the radius of the ball. Mainly can bear radial load.

2. In addition to the open type, there are bearings with steel plate dust cover, bearings with contact rubber seals, bearings with non-contact rubber seals, or bearings with snap rings on the outer diameter of the outer ring. .

3. The ball bearing with dust cover or sealing ring is sealed with an appropriate amount of high-quality grease. Deep groove ball bearings generally use steel stamping cages, with small friction torque and a precision grade of 0.
