The Ultimate Deep Groove Ball Bearings Guide

Jun. 10, 2025 Share:

Deep Groove Ball Bearing is one of the core components widely used in all kinds of machinery and equipment. With its unique structure and excellent performance, it meets the demand for high efficiency, reliability and long life in many industrial and commercial fields. Whether in high-speed machinery, automobile engines, or high-precision requirements of industrial equipment, Deep Groove Ball Bearing plays a vital role. In this article, we will discuss in detail how Deep Groove Ball Bearing works, its main applications and how to choose the right Deep Groove Ball Bearing for different needs to help you better understand this key component.


What is Deep Groove Ball Bearing? 

Deep Groove Ball Bearing is a type of ball bearing with a “deep groove” or radial raceway. Its design allows this type of bearing to withstand radial and axial loads in both directions, making it ideal for a wide range of industrial applications.

Deep Groove Ball Bearing not only withstands loads, but also reduces friction between moving surfaces, thus increasing the efficiency and durability of the equipment. Especially in high-speed applications, Deep Groove Ball Bearing excels in reducing friction and improving efficiency due to its precision design and high quality balls. The structural optimization of the raceway minimizes the contact surface between the balls and the raceway, further reducing internal friction and ensuring smooth operation even at high speeds.

Another significant advantage is its low noise and low vibration performance. Precision manufactured ball and raceways not only provide quiet operation, but also effectively reduce equipment vibration, making them particularly suitable for equipment requiring a quiet environment.


How Deep Groove Ball Bearing works 

Deep Groove Ball Bearing reduces friction between contact surfaces by means of balls rolling along the raceways of the inner and outer rings. When the bearing is loaded, the balls roll within the raceways, avoiding direct sliding between the two planes, which greatly reduces friction. This structure enables Deep Groove Ball Bearing to withstand both radial and axial loads and maintain efficient and smooth operation.


Main Applications of Deep Groove Ball Bearing 

Deep Groove Ball Bearing is widely used in many fields due to its ability to withstand both radial and axial loads.

1. Automotive Industry

Deep Groove Ball Bearing plays an important role in automotive engines, transmissions, transmissions, and wheel hubs, ensuring the stability and efficiency of these critical components.

2. Aerospace Industry

Under extreme temperature and pressure conditions, Deep Groove Ball Bearing provides reliable support for critical systems such as aircraft engines and navigation equipment, ensuring the reliability and durability of aircraft.

3. Home Appliances

For example, in home appliances such as washing machines and vacuum cleaners, Deep Groove Ball Bearing ensures low noise and vibration when the equipment is in operation, which improves the user experience and prolongs the life of the equipment.

4. Machine Tools

In high-precision, high-strength machine tools, Deep Groove Ball Bearing provides accuracy assurance and reduces equipment downtime through its long life and high reliability.

5. Heavy Industry Applications

The large Deep Groove Ball Bearing is also used in a wide range of applications in areas such as rock crushing, pulp, steel rolling mills, the wind energy industry, and construction machinery.

6. Other Industries

Deep Groove Ball Bearing is also widely used in mining, petrochemical, steel, cement, natural gas and other industries to ensure the efficient operation of various industrial equipment.


Types and Classification of Deep Groove Ball Bearing 

1. Classification by Sealing Method 

Dustproof cover type (ZZ): applicable to the working condition where the inner ring is rotating, it can prevent dust from entering and keep the grease, but will not increase the friction loss.

Non-contact sealing type (RZ): the sealing effect is better, and will not affect the speed of the bearing, usually made of steel skeleton reinforced nitrile rubber.

Contact sealing type (RS): provide stronger dustproof and waterproof ability, but the friction is larger, suitable for lower speed and higher requirements for sealing conditions.

2. Classification by Arrangement 

Single Row Deep Groove Ball Bearing: the most common type, suitable for most regular applications.

Deep Groove Ball Bearing: Filled with more steel balls for higher load carrying capacity, suitable for heavy load environment.

Double Row Deep Groove Ball Bearing: Capable of withstanding large radial and axial loads at the same time, suitable for equipment with high precision requirements.

3. Classified by material 

Stainless Steel Deep Groove Ball Bearing: Good corrosion resistance, suitable for wet or corrosive environments.

Full Ceramic Deep Groove Ball Bearing: Suitable for high temperature and special environments, self-lubricating and able to operate under harsh conditions.

Plastic Deep Groove Ball Bearing: Lightweight with good insulation for low load and noise sensitive applications.


How to select Deep Groove Ball Bearing? 

When selecting Deep Groove Ball Bearing, you need to consider the following key factors according to the actual application scenarios: 

1. The size and nature of loads

Deep Groove Ball Bearing is suitable for light and medium loads, for heavy and shock loads, it is recommended to select a bearing with higher For heavy loads and shock loads, it is recommended to select a bearing with higher load carrying capacity.

2. Speed Requirements

Deep Groove Ball Bearing is suitable for high speed rotation, but different types of seal covers, lubrication methods, etc. will affect its speed performance. Ensure that the selection matches the actual speed requirements.

3. Operating Environment

The operating environment of the bearing determines the type selected. For example, stainless steel or corrosion-resistant bearings may be selected for wet or corrosive environments; ceramic bearings should be selected for high-temperature environments.

4. Cost Considerations

Deep Groove Ball Bearing's low cost makes it suitable for a wide range of low-cost applications. Choosing the right type can reduce production costs while maintaining performance.
