Product Description

Advantages Small frictional resistance: The rolling elements and the raceways mainly have rolling friction. Compared with sliding bearings, its friction coefficient is significantly reduced, which can effectively reduce energy consumption and improve mechanical efficiency. High limiting speed: Due to low friction and less heat generation, it can maintain good stability and reliability under high-speed rotation conditions, making it suitable for equipment that requires high rotation speeds. Simple structure: Composed of basic components such as the inner ring, outer ring, rolling elements, and cage, it has a relatively simple structure, a mature manufacturing process, low cost, and is easy for mass production and application. Wide application range: It can bear radial loads and a certain amount of axial loads, and can be used in various mechanical equipment and working environments, with strong adaptability to loads and rotation speeds.

• Deep groove ball bearings are one of the most common types of rolling bearings. The following mainly introduces their
  content from aspects such as structure, characteristics, and applications:
  Structure
  Inner ring: It is usually matched with the shaft. The inner diameter of the inner ring is in line with the shaft diameter. The raceway of the inner ring is one of the tracks on which the rolling elements inside the bearing roll.
  Outer ring: Generally installed in the bearing seat or the hole of mechanical components. The outer diameter of the outer ring is suitable for the mounting hole, and its raceway, together with that of the inner ring, provides a rolling path for the rolling elements.
  Rolling elements: Usually steel balls, which are located between the raceways of the inner and outer rings. They are the key components for realizing the rolling motion of the bearing. When the inner and outer rings rotate relative to each other, the steel balls roll in the raceways, reducing friction.
  Cage: Also known as the retainer. Its function is to evenly separate the rolling elements to prevent collisions and friction between them. At the same time, it guides the rolling elements to roll correctly in the raceways, enabling the bearing to run smoothly.
  Characteristics

  • Advantages
  • Small frictional resistance: The rolling elements and the raceways mainly have rolling friction. Compared with sliding bearings, its friction coefficient is significantly reduced, which can effectively reduce energy consumption and improve mechanical efficiency.
  • High limiting speed: Due to low friction and less heat generation, it can maintain good stability and reliability under high-speed rotation conditions, making it suitable for equipment that requires high rotation speeds.
  • Simple structure: Composed of basic components such as the inner ring, outer ring, rolling elements, and cage, it has a relatively simple structure, a mature manufacturing process, low cost, and is easy for mass production and application.
  • Wide application range: It can bear radial loads and a certain amount of axial loads, and can be used in various mechanical equipment and working environments, with strong adaptability to loads and rotation speeds.
  • Disadvantages
  • Relatively limited load-carrying capacity: Compared with some bearings specifically designed to bear heavy loads, such as roller bearings, the load-carrying capacity of deep groove ball bearings is relatively low. When bearing large radial or axial loads, problems such as premature wear or fatigue failure may occur.
  • High requirements for installation accuracy: If there are deviations during installation, such as a large coaxiality error between the shaft and the bearing seat, it will cause uneven force on the rolling elements, affecting the service life and performance of the bearing, and may even lead to early damage of the bearing.
  • Applications
  • Industrial field: Widely used in various equipment such as motors, reducers, machine tool spindles, textile machinery, and printing machinery. It provides support and positioning for the rotating parts of these devices to ensure the normal operation of the equipment.
  • Automotive industry: It is applied in parts such as the engine, transmission, and wheel hubs of automobiles. For example, the crankshaft bearings of the engine, the input and output shaft bearings of the transmission, and the wheel hub bearings play an important role in the power transmission and driving stability of the automobile.
  • Home appliance products: Deep groove ball bearings are often used in the motors of home appliances such as air conditioners, washing machines, and refrigerators, ensuring the high-efficiency operation and low-noise performance of the motors, and improving the user experience and reliability of home appliance products.
  • Other fields: It also has a wide range of applications in many fields such as medical devices, office equipment, and power tools, and is an indispensable and important basic component in modern mechanical industry.
