Product Description
Deep groove ball bearings (GB/T 276-2003) The original list of radial ball bearings is the most widely used rolling bearing. It is characterized by small frictional resistance and high speed and can be used on parts that bear radial loads or joint loads that act simultaneously in radial and axial directions and can also be used on parts that bear axial loads, such as small-power motors, Automotive and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.
Deep groove ball bearings are the most common type of rolling bearings:
The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls, and a set of cages. There are 2 types of deep groove ball bearings: single-row and double-row. The structure of deep groove balls is also divided into 2 types: sealed and open. The open type means that the bearing does not have a sealed structure. seal. The material of the dust-proof sealing cover is stamped steel plate, which simply prevents dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent the grease in the bearing from overflowing.
The type code of single row deep groove ball bearing is 6, and the code name of double row deep groove ball bearing is 4. Its structure is simple, and easy to use, and it is the most commonly produced and widely used type of bearing.
According to the size of deep groove ball bearings, they can be divided into:
(1) Miniature bearings – bearings with a nominal outer diameter of 26mm or less;
(2) Small bearings – bearings with a nominal outer diameter ranging from 28 to 55mm;
(3) Small and medium-sized bearings – bearings with a nominal outer diameter ranging from 60-115mm;
(4) Medium and large bearings – bearings with a nominal outer diameter ranging from 120-190mm
(5) Large bearings – bearings with a nominal outer diameter ranging from 200-430mm;
(6) Extra-large bearings – bearings with a nominal outer diameter of 440mm or more.

What are the Common Signs of Wear or Damage in Ball Bearings that Indicate the Need for Replacement?
Ball bearings are subjected to wear and stress during operation, and over time, they may exhibit signs of damage or deterioration that warrant replacement. Recognizing these signs is crucial to prevent catastrophic failure and ensure safe and reliable operation. Here are the common signs of wear or damage in ball bearings:
- Unusual Noise:
If you hear unusual grinding, clicking, or rumbling noises coming from the bearing during operation, it may indicate worn-out or damaged components. Unusual noise suggests that the bearing is no longer operating smoothly.
- Vibration:
Excessive vibration in the machinery can be a sign of bearing wear. Vibrations can result from uneven wear, misalignment, or damaged components within the bearing.
- Increased Temperature:
Higher operating temperatures than usual may indicate increased friction due to inadequate lubrication, wear, or other issues. Monitoring the bearing’s temperature can help identify potential problems.
- Irregular Movement:
If you notice irregular movement, jerking, or sticking during rotation, it could be a sign that the bearing is no longer operating smoothly. This may be due to damaged rolling elements or raceways.
- Reduced Performance:
If the machinery’s performance has decreased, it may be due to a compromised bearing. Reduced efficiency, increased energy consumption, or a decline in overall performance could be indicators of bearing wear.
- Visible Wear or Damage:
Inspect the bearing for visible signs of wear, such as pitting, scoring, or discoloration on the rolling elements or raceways. Severe wear or damage is a clear indication that the bearing needs replacement.
- Leakage or Contamination:
If there is evidence of lubricant leakage, contamination, or the presence of foreign particles around the bearing, it suggests that the seal or shield may be compromised, leading to potential damage.
- Looseness or Excessive Play:
If you can feel excessive play or looseness when manually moving the bearing, it could indicate worn-out components or misalignment.
- Reduced Lifespan:
If the bearing’s expected lifespan is significantly shorter than usual, it may be due to inadequate lubrication, excessive loads, or improper installation, leading to accelerated wear.
- Frequent Failures:
If the bearing is consistently failing despite regular maintenance and proper use, it could indicate a chronic issue that requires addressing, such as inadequate lubrication or misalignment.
It’s important to conduct regular inspections, monitor performance, and address any signs of wear or damage promptly. Replacing worn or damaged ball bearings in a timely manner can prevent further damage to machinery, reduce downtime, and ensure safe and efficient operation.
What Role do Seals and Shields Play in Protecting Ball Bearings from Dirt and Debris?
Seals and shields are critical components of ball bearings that play a crucial role in protecting them from dirt, debris, moisture, and contaminants in various applications. These protective features help maintain the integrity of the bearing’s internal components and ensure reliable operation. Here’s how seals and shields contribute to bearing protection:
- Contaminant Exclusion:
Seals and shields create a physical barrier between the external environment and the bearing’s interior. They prevent dust, dirt, water, and other contaminants from entering the bearing and coming into contact with the rolling elements and raceways.
- Lubrication Retention:
Seals and shields help retain lubrication within the bearing. They prevent the lubricant from escaping and contaminants from entering, ensuring that the bearing remains properly lubricated for smooth operation and reduced friction.
- Corrosion Prevention:
Seals and shields protect bearing components from exposure to moisture and corrosive substances. By preventing moisture ingress, they help extend the bearing’s lifespan by minimizing the risk of corrosion-related damage.
- Extended Bearing Life:
Seals and shields contribute to the overall longevity of the bearing by reducing wear and damage caused by contaminants. They help maintain a clean internal environment, which promotes proper rolling contact and minimizes the risk of premature failure.
- Enhanced Performance in Harsh Environments:
In applications exposed to harsh conditions, such as outdoor machinery or industrial settings, seals and shields are vital. They protect bearings from abrasive particles, chemicals, and extreme temperatures, ensuring reliable performance despite challenging conditions.
- Noise and Vibration Reduction:
Seals and shields can help reduce noise and vibration generated by the bearing. They provide additional damping and stability, contributing to smoother operation and enhanced user comfort in noise-sensitive applications.
- Customized Protection:
Manufacturers offer a variety of seal and shield designs to suit different application requirements. Some seals provide higher levels of protection against contamination, while others are designed for high-speed or high-temperature environments.
- Trade-Offs:
While seals and shields offer significant benefits, they can also introduce some friction due to contact with the bearing’s inner or outer ring. Engineers must balance the level of protection with the desired operating characteristics, considering factors like friction, speed, and environmental conditions.
Overall, seals and shields play a vital role in maintaining the integrity and performance of ball bearings. By effectively preventing contaminants from entering and preserving lubrication, they ensure the smooth and reliable operation of machinery and equipment in a wide range of applications.
What Factors should be Considered when Selecting a Ball Bearing for a Particular Application?
Selecting the right ball bearing for a specific application involves careful consideration of various factors to ensure optimal performance, longevity, and reliability. Here are the key factors that should be taken into account:
- Load Type and Magnitude:
Determine the type of load (radial, axial, or combined) and the magnitude of the load that the bearing will need to support. Choose a bearing with the appropriate load-carrying capacity to ensure reliable operation.
- Speed and Operating Conditions:
Consider the rotational speed of the application and the operating conditions, such as temperature, humidity, and exposure to contaminants. Different bearing types and materials are suited for varying speeds and environments.
- Accuracy and Precision:
For applications requiring high accuracy and precision, such as machine tool spindles or optical instruments, choose high-precision bearings that can maintain tight tolerances and minimize runout.
- Space Limitations:
If the application has limited space, choose miniature or compact ball bearings that can fit within the available dimensions without compromising performance.
- Thrust and Radial Loads:
Determine whether the application requires predominantly thrust or radial load support. Choose the appropriate type of ball bearing (thrust, radial, or angular contact) based on the primary load direction.
- Alignment and Misalignment:
If the application experiences misalignment between the shaft and housing, consider self-aligning ball bearings that can accommodate angular misalignment.
- Mounting and Installation:
Consider the ease of mounting and dismounting the bearing. Some applications may benefit from features like flanges or snap rings for secure installation.
- Lubrication and Maintenance:
Choose a bearing with appropriate lubrication options based on the application’s speed and temperature range. Consider whether seals or shields are necessary to protect the bearing from contaminants.
