Benefits of Deep Groove Ball Bearings

Several household appliances use Deep Groove Ball Bearings for their quiet and long service life. One example is the floor polisher motor, which uses two single-row Deep Groove Ball Bearings, which require contacting rubber seals and proper lubrication. Read on for more information about this type of bearing. Listed below are some of the benefits of Deep Groove Ball Bearings. So, what are they?

High speeds

The NTN Corporation has developed a new type of high-speed deep groove ball bearing with grease lubrication. This bearing features a double-rotational speed and is capable of the highest level of high-speed rotation in the industry. This type of bearing was designed with the compact size and weight in mind, and required an even higher level of high-speed rotation to be efficient and durable. Conventional grease-lubricated deep groove ball bearings suffered from problems involving high temperatures and a lack of lubrication due to grease scattering.

Radial loads

In order to prevent slipping, deep groove ball bearings need to withstand a sufficiently high radial load. This is usually much higher than the requisite minimum load. Here are some guidelines for determining a suitable radial load. Read on to learn more. Radial loads on deep groove ball bearings vary greatly from one series to the next. The following table highlights the basic features of radial loads on deep groove ball bearings.

Minimal maintenance

To ensure optimal performance of your deep groove ball bearing, you should perform minimal maintenance every once in a while. This maintenance is not limited to changing the ball. In fact, the later period of the life of your bearing is also subject to dust and impurity accumulation. These particles enter the rubbing surface between the outer ring ball track and the ball, affecting its smooth operation. This impurity is difficult to remove and is also inconvenient. Fortunately, there are some simple ways to minimize this problem.

Suitable for axial misalignment

When choosing a deep groove ball bearing, one has to take into account the degree of axial misalignment. The maximum amount of misalignment for a bearing is dependent on its type and internal clearance while it is in operation. The maximum misalignment can also be affected by shaft alignment. The standard L10 calculation assumes that the bearing is well-aligned. However, the actual misalignment tolerance depends on the type of bearing, the load, and the internal clearance during operation. To calculate the fatigue life of a deep groove ball bearing or a roller bearing, you need to know the difference between the two.

No seals

No seals on deep groove ball bearings are a common occurrence in modern machines and equipment. Although they are not essential, these seals can protect the bearing from contamination and retain lubrication. The presence of seals also ensures that contaminants cannot penetrate the inner surfaces of the bearing, ensuring that the device can withstand the conditions that it is subjected to. Here are some advantages of sealed bearings.

Plastic cages

Deep groove ball bearings have several important features. These include cages that keep the balls in position. The dimensions of the cages are determined by the ratio of the cage web width to the square root of the pocket diameter. In order to design cages that are suitable for these types of bearings, NSK first evaluated the size, shape, and deformation of the bearings and used CAE technology to analyze the key attributes of the cage. Then, the company developed physical prototypes to validate the cage performance during rotation. As a result, the company was able to cut development time by one-third and achieve its goal of producing high-quality plastic cages for deep groove ball bearings.

Non-contact seals

Sealing is an integral part of rolling bearings. The quality of the sealing system determines the efficiency of a rolling bearing. A seal must protect against contaminants, moisture, and grease, and should be capable of reducing frictional torque while maintaining low heat generation. Non-contact seals can be used on deep groove ball bearings with a range of speeds. Generation C deep groove ball bearings use sealing shields as part of their design.

Impact resistance

Amongst the major advantages of deep groove ball bearings is their high impact resistance. Rubber cannot withstand high impact and is therefore not an excellent choice for bearing heavy loads. Moreover, the bearings can be operated in a wide variety of harsh environments, including oil, seawater, and solvents. Therefore, these bearings are made from high-quality materials such as Polyetherimide, PVDF, and PTFE.
