Deep Groove Ball Bearings
A deep groove ball bearing has an outer ring, an inner ring, steel balls, and cages. There are single-row and double-row types. Deep groove ball structures are also divided into sealed and open structures. Open type means that the bearing does not have a sealed structure. Sealed deep groove ball bearings are categorized into dust-proof and oil-proof types. The dust-proof sealing seal, made of stamped steel plate, simply prevents dust from entering the bearing raceway. In contrast, the oil-proof type uses a contact oil seal to prevent the escape of grease and oil from bearing.
The most frequently used bearing constructions in the world are Deep Groove Ball Bearings. DGBBs are capable of undertaking high radial and moderate axial loads, in addition to possessing high-speed abilities. The outer and bore rings have grooves with a radius just over the ball radius. The depth of the groove allows the bearing to support both radial and axial forces. The balls that are intended to be loaded into this typical non-loading slot type of deep groove ball bearing are held in an eccentric position with respect to the bearing rings.

Single Row Deep Groove Ball Bearing
Single-row deep groove ball bearings feature deep groove raceways on the inner as well as outer rings. The deep groove raceway and the excellent tightness between the raceway and the steel ball enable this type of bearing to withstand a certain two-way axial load while bearing a radial load. Increasing the radial clearance of the bearing enhances its ability to withstand axial loads. Therefore, it can sometimes be used to replace high-speed angular contact ball bearings.
Application of Single Row Deep Groove Ball Bearing
Single row deep groove ball bearings are likely the most popular type of bearings due to their multi-functional use and simple design, with minimal equipment and expectations on performance. They are characterized by deep raceways, ability to support radial loads and also moderate axial loads acting from both sides, and pretty much possess a single row of balls in them, which does in fact provide a simple yet very capable bearing solution.
The applications for single row deep groove ball bearings are numerous across different sectors and types of machines owing to their special characteristics and several advantages.
1) General Machinery and Electric Motors: Electric motors and general machinery is among the most common applications of the single row deep groove ball bearings that can take in moderate speeds and provide not much noise yet efficient operation. These bearings are, therefore, primarily used in household appliances, power tools, fans, and small to medium-sized electric motors.
2) Automotive: Single row deep groove ball bearings are widely used for applications in alternators, starters, clutches, and transmissions in the automotive sector. Its robustness and reliability in different operational conditions made them favorable for such applications.
3) Industrial Gearboxes: Industrial gearboxes, generally used for precise and smooth rotation, involve single row deep groove ball bearings in their construction. Load can be exerted in both radial and axial directions, and that too rather efficiently, along with low friction involved.
4) Pumps and Compressors: High radial loads with varying speeds are common in equipment such as pumps or compressors, and so these bearings have frequent application because of their ability to give long-lasting service while withstanding this load.
5) Agricultural Machinery: Other agricultural machinery such as tractors, combines, and even others use single-row deep-groove bearings, not only for their durability but also for their ability to work optimally in environments laden with dust and moisture.
6) Material Handling Systems: Conveyor systems or other material handling equipment totally rely on these bearings for their efficient operation
7) Precision Instruments: In high-speed machinery or medical devices or other high craftsmanship requirements, single-row deep-groove bearings are most cherished for their precision in functioning and low noise. They are also incorporated in fun applications like skateboards, inline skates, and bicycles, where small size and efficient handling of radial and axial loads takes precedence.
Double Row Deep Groove Ball Bearing
Applications of Double Row Deep Groove Ball Bearing
Double-row deep groove ball bearings are widely utilized in various industrial sectors: heavy industrial machinery, power generation and the energy industry, automotive and transportation, aerospace, agriculture and food processing.
Heavy Industrial Machinery
- Construction Machinery: In construction machinery, double-row deep groove ball bearings have extensive application in transmission devices, steering systems and other critical components. They can withhold a great load while ensuring the smooth and stable operation of equipment.
- Excavators: The operation environment of the excavators is very complex; it requires the bearings to withstand heavy radial and axial loads. Double-row deep groove ball bearings meet such requirements and ensure the normal work of the excavators.
- Metallurgical equipment: Under the conditions of high temperatures and very strong corrosive environments, double-row deep-groove ball bearings possess good resistance performance, thus being widely used in metallurgical equipment such as steel rolling mills, blowing furnaces, etc.
- Mining machinery: Double-row deep groove ball bearings in mining, mineral processing and powder equipment are used to support large radial and axial loads to ensure stable operation of the corresponding reducer and transmission device.
Power Generation and Energy
Double-row deep groove ball bearings are very important to the work of hydroelectric power plants. It is the long-term operation and complex altering of load levels that afflicts hydroelectric equipment. That is why in such machinery these bearings are an ideal choice, the dependability and durability of double-row deep groove ball bearings are not under discussion. These types of bearings would provide stable support for the rotating parts of the turbine and ensure the full operation of the hydroelectric power plant.
Double-row deep groove ball bearings used in solar tracking systems transmit and carry torque. Due to their unique rolling mechanism and seal, they can ensure high-speed movement and long lifetime, which are able to hold stability in difficult conditions and continuous operation.
Automotive and Transport
- Engine: Double-row deep groove ball bearings are primarily used to support the crankshaft and other important parts to maintain the stable operation of the engine. Due to its high resistance to radial load and stability under high-speed rotation, it can meet the demands of the engine under all work conditions.
- Transmission: Double-row deep groove ball bearings are fitted on a transmission in order to hold the rotation of the shaft as well as that of the gears to enable the transmission to be used as needed under varying conditions of driving. Specifically in transmissions used manually, the bearings permit the shafts as well as the gears to move at variable speeds as they respond to varied driving conditions.
- Steering gear: Steering gear bearings must be able to endure heavy radial loads and impacts. Double-row deep groove ball bearings, by their high bearing capacity and resistance to wear, can provide the steering gear with reliable operation.
