Deep Groove Ball bearing, is one of our most common types of bearings, production and life application is extremely wide. Then why is it called Deep groove ball bearing?

Because of the structure of Deep groove ball bearing, an outer ring, an inner ring, a middle Deep groove, arranged with rolling steel balls, so very image called Deep groove ball bearing.

Deep groove ball bearing is the most typical structure of rolling bearing, which has small friction torque and is most suitable for high speed, low noise and low vibration environment.

Deep Groove Ball bearing features

The groove on the inner and outer rings has an interface radius slightly larger than the sphere radius and is in an arc shape. Mainly can bear radial load.

In addition to the type of bearings, there are bearings with a steel dust cover, bearings with a contact rubber seal, bearings with a non-contact rubber seal, or bearings with a stop ring on the outer diameter of the ring.

Ball bearings with dust caps or seals contain an appropriate amount of high-quality grease. Deep groove ball bearing generally uses steel plate stamping cage, the friction moment is small, the precision grade is 0.

Taking NSKDEEP groove ball bearing as an example, Deep groove ball bearing is divided into three types

1.Dust cover type (ZZ Type)

Low friction moment. Good speed. Water-resistant discomfort.

2.Non-contact rubber sealing ring type (VV Type)

Low friction moment. Good speed. Good dust resistance. Water-resistant discomfort.

3.Contact rubber sealing ring type (DDU Type)

Low friction moment. Good speed. Good dust resistance.Good waterproof.
