Double Row Deep Groove Ball Bearings

Double Row Deep Groove Ball Bearings are an innovative product designed to meet the dynamic needs of the manufacturing industry. These bearings are a perfect fit for heavy machinery and devices that require high precision and a long-lasting performance. With advancements in engineering and manufacturing techniques, deep groove ball bearings have become an essential component in a wide range of industries. In this product introduction, we will look at what makes double row deep groove ball bearings unique and the benefits that they can offer to your business.

Construction and Design

Double row deep groove ball bearings are designed to provide optimal performance and durability even in the most severe conditions. These bearings have two sets of ball bearings arranged in a double row configuration, which allows for increased load capacity and radial stiffness. They are made of high-quality materials such as steel, which makes them perfect for applications that require high precision and durability.

Durability

One of the key benefits of double row deep groove ball bearings is their long life expectancy, which is due to their robust design and the high-quality materials used in manufacturing. They can handle heavy loads, high speeds, and are resistant to extreme temperature fluctuations, vibrations, and shock loads. This robust design leads to reduced wear and tear, which results in a longer lifespan of the bearings, leading to reduced maintenance and replacement costs in the long term.

Versatility

Double row deep groove ball bearings are highly versatile and can be used in a wide range of applications in the manufacturing industry. From small home appliances to large industrial equipment, these bearings are designed to meet the needs of any application. They can be used in various environments, such as high-temperature environments, corrosive environments, and cleanroom environments. This versatility makes them an excellent choice for manufacturers who demand high-performance, durability, and reliability in their bearings.

Load Capacity and Radial Stiffness

Double row deep groove ball bearings have a higher load capacity than their single-row counterparts. They provide increased radial stiffness, which allows them to withstand higher loads without deformation or damage to the bearings. This feature also allows the bearings to maintain their radial position and protect the shaft under heavy loads, leading to reduced damage to the equipment and longer lifespan.

Noise and Vibration Reduction

Another advantage of Double Row Deep Groove Ball Bearings is their exceptional noise and vibration reduction properties. This feature is highly sought after in industries such as home appliance manufacturing, medical equipment manufacturing, and electronic equipment manufacturing. The robust design of the bearings reduces the amount of noise and vibration by absorbing impacts and maintaining accurate shaft positioning, ensuring quiet, smooth, and stable operation of the equipment.

Conclusion

In conclusion, Double Row Deep Groove Ball Bearings are an ideal solution for any manufacturer who is looking for high-performance, durable, versatile, and reliable components for their equipment. With their robust design, high load capacity, resistance to extreme environmental and operating conditions, and exceptional noise and vibration reduction properties, these bearings can provide significant benefits to your manufacturing process. By choosing Double Row Deep Groove Ball Bearings, you are ensuring a low-maintenance, efficient, and highly performing product that is designed to meet your needs.

● Introduction

In design, the double row deep groove ball bearings are basically the same as the Single Row Deep Groove Ball Bearings. The bearing consists of an inner ring, an outer ring, two sets of cages and two sets of steel balls, and two nylon cages are inserted into the two sides of the bearing respectively. In addition to having a radial load capacity 1.62 times higher than that of single row deep groove ball bearings, the bearing can also withstand axial loads. In addition to bearing radial loads, Bearings can also withstand axial loads acting in both directions. Double row deep groove ball bearings are suitable for a bearing arrangement where single row deep groove bearings cannot be loaded. Under normal circumstances, if the bearing is to bear pure axial load, it should not exceed 0.5Co. Excessive axial load may greatly reduce the working life of the bearing. The external dimensions of the bearings accord with DIN 625-3, the dimensional tolerances and rotational accuracy accord with standard DIN 620.

Bearings are used in many fields, including machinery and equipment, precision instruments, machine tool equipment, conveying equipment, agricultural machinery, textile machinery, industrial equipment, etc.

● Bearing Series

The types of the double groove ball bearing include 4200 series and 4300 series.

● Production Details

◆ Process of machining inner and outer rings

The process of inner ring processing: grinding end face → rough grinding inner diameter → fine grinding outer diameter → inner groove (branch outer diameter) → fine grinding inner diameter (branch outer diameter) → inner groove superfinishing (branch outer diameter or inner diameter).

The process of outer ring processing: grinding end face→grinding outer diameter→finishing outer diameter→grinding outer groove→superfinishing outer groove.

◆ Sampling inspection

The theoretical basis of sampling test is probability theory, mathematical statistics, management and economics. It is an important part of statistical quality control and one of the contents of quality assurance model. Sampling inspection should reflect scientificity and usability. A "good" sampling inspection system includes the lowest inspection cost (economical), effective control of product quality (scientificity), and inspection of product quality and reliable evaluation conclusions (reliability), and easy implementation (usability) .

● Bearing Static Load Rating

The rated static load of the bearing refers to the total permanent deformation of 0.0001 times the diameter of the rolling element at the contact center of the rolling element and the raceway that can withstand the maximum load. It is the equivalent static load that does not affect the subsequent operation of the bearing. Depending on the requirements for smooth running and friction, and the actual contact surface geometry, the allowable equivalent static load can be less than, equal to or greater than the rated static load. Selected by calculating the static load safety factor F. In general, it requires a bearing with smooth operation and extremely low noise, the value of F should be high. For occasions where only moderate running noise is required, the value of F can be smaller. Recommended selection: F=1.5~2.5 is suitable for low noise requirements. F=1.0~1.5 is suitable for normal noise requirements. F=0.7~1.0 is suitable for medium noise requirements.
