Deep groove ball bearings are one of the 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 centripetal ball bearings. Its English name Deep groove ball bearing, literal translation is deep groove ball bearing, this is why it is called deep groove ball bearing. Of course, there is another reason, that is, the structure of the deep groove ball bearing, which is obvious in the following picture. An outer ring, an inner ring, a deep groove in the middle, arranged with rolling steel balls, so it is very image called deep groove ball bearings.
As far as the classification of bearings is concerned, deep groove ball bearings are the most typical structural form of rolling bearings, with small friction torque, which is most suitable for requiring high speed, low noise, low vibration environment, etc., and is widely used.
Product characteristics
1, located in the inner ring, the channel on the outer ring, the interface radius is slightly larger than the radius of the ball is circular. It can mainly withstand radial load.
2. In addition to the open type of bearings, there are bearings with steel plate dust cover and bearings with contact rubber sealing ring and bearings with non-contact rubber sealing ring, or bearings with a stop ring on the outer diameter of the outer ring.
3, with dust cover or sealing ring type ball bearings, sealed into the appropriate amount of high-quality grease. Deep groove ball bearings generally use steel plate stamping cages, small friction torque, accuracy level of 0.
Deep groove ball bearings can be divided into three categories according to dust cover/sealing ring
1, dust cover type
Small friction torque, good high speed, waterproof discomfort
2, non-contact rubber sealing ring type
Small friction torque, high speed, good dust resistance, waterproof discomfort
3, contact rubber sealing ring type
The friction torque is small, the high speed is good, the dust resistance is good, the water resistance is good
