Deep Groove Ball Bearings

Deep Groove Ball Bearing

Descriptions of Deep Groove Ball Bearings
Deep groove ball bearings are the most extensively used bearings that are simple in design and are inseparable. The commonly used deep groove ball bearings are shielded deep groove ball bearings, open type deep groove ball bearings, single row deep groove ball bearings, and double row deep groove ball bearings.
There is a deep groove race way on the inner and outer ring of the deep groove ball bearing.

Features of Deep Groove Ball Bearings
1. Our deep groove ball bearings can operate at extremely high speed. They are so durable that little maintenance is needed during operation.
2. The bearings are mostly used to carry radial load. However, they can also carry a certain axial load. They can carry much heavy axial load if the radial clearance is increased, so they can substitute for angular contact ball bearings.
3. Most of our deep groove ball bearings adopt machined solid cage.
4. Compared to other types of bearings with the same size, our deep groove ball bearings have the advantages of minimum friction and the highest permissible rotary speed.
5. Our deep groove ball bearings are suitable for use in electric-bicycles, motorbike, electric tools, air conditioners, lawnmowers, and water pumps, etc.

Parameters of Deep Groove Ball Bearing

Different Types of Deep Groove Ball Bearings
Our large size deep groove ball bearings can be divided into several types according to their different structures.
1. Deep groove ball bearings with filling slot,
2. Deep groove ball bearings with snap ring groove on outer ring,
3. Deep groove ball bearings with dust cover,
4. Deep groove ball bearings with seals,
5. Deep groove ball bearings with flange on outer ring,
The bearing must bear a certain minimum radial load, so that there would not be detrimental sliding phenomenon between the rolling elements and raceways, which is caused by centrifugal force of the cage and balls while the bearing is rotating at high speed.
The values of the minimum radial load can be estimated according to the following formula:

Among which
Frm is the minimum radial load, kN
kr is the minimum load factor, (referring to the following table).
ν is the oil viscosity at working temperature, mm2/s
n is the rotary speed, r/min
dm is the average diameter of bearing =0,5 (d + D), mm

Bearing series	618	619,160	60,161,62	63	64
Kr	15	20	25	30	35

Permissible Angle of Inclination
The permissible relative angle of inclination between inner ring and outer ring can be seen in the table below according to bearing clearance.

Radial internal clearance	permissible angle of inclination
0	8'
3	12'
4	16'

Tolerance
In general, the bearing tolerance of our large size deep groove ball bearing is 0 grade. As a professional deep groove ball bearing manufacturer in China, we can also produce deep groove ball bearings with tolerance of P6 or P5 Grade, upon request.
In addition to deep groove ball bearings, we also supply cylindrical roller bearings, taper roller bearing, thrust bearings, and angular contact ball bearings, etc.
Our bearings are of high quality and low price. They are sold to Korea, Japan, Thailand, Malaysia, Greece, Italy, Spain, Canada, Mexico, America, Argentina, Brazil and more.
