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

In fact, deep groove ball bearings have another academic name, single row radial ball bearings. There is an outer ring, an inner ring, and a deep groove in the middle, lined with rolling steel balls, so it is very vividly called a deep groove ball bearing.

As far as the classification of bearings is concerned, deep groove ball bearings are the most typical structural form among rolling bearings. They have small friction torque and are most suitable for environments requiring high speed, low noise, and low vibration. They are widely used.

Features

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

2. In addition to the separate type of bearings, there are also bearings with steel plate dust covers, bearings with contact rubber seals, bearings with non-contact rubber seals, or bearings with stop rings on the outer diameter of the outer ring. .

3. Ball bearings with dust covers or sealing rings are filled with an appropriate amount of high-quality grease. Deep groove ball bearings generally use steel plate stamped cages, which have small friction torque and an accuracy level of 0.

Deep groove ball bearings are divided into three categories

1. Dust cover type (ZZ type)

Frictional torque is small

Good high speed performance

Not very waterproof

2. Non-contact rubber seal type (VV type)

Frictional torque is small

Good high speed performance

Good dust resistance

Not very waterproof

3. Contact rubber seal type (DDU type)

Frictional torque is small

Good high speed performance

Good dust resistance

Good water resistance

How to select and search for deep groove ball bearings, first confirm the model

Bearing code examples:

①Bearing type code 6: deep groove ball bearing

②Dimension code 2: 02 series, 3: 03 series, 9: 19 series, 0: 10 series

③If the inner diameter code is less than or equal to 03, the bearing inner diameter 00: 10mm, 01: 12mm, 02: 15mm, 03: 17mm is greater than or equal to 04, the bearing inner diameter code is X5 (mm)

④Sealing ring Dust cover code ZZ: steel plate on both sides, DDU: contacting rubber sealing ring on both sides, VV: non-contacting rubber sealing ring on both sides

⑤ Clearance code omitted: CN clearance*, C3: greater than CN clearance, C4: greater than C3 clearance, CM: for electric motor*

⑥Grease code NS7: NS HI-LUBI
