Basic Parameters

The first digit "3" indicates that the bearing type is a double row angular contact ball bearing. This type of bearing can simultaneously bear radial load and bidirectional axial load, and has high rigidity and rotational accuracy. It is suitable for occasions that require high operating accuracy and can bear large combined loads.
The second digit "2" represents the width series of the bearing. The width series is mainly used to distinguish bearings with the same inner diameter and outer diameter but different widths. To a certain extent, it affects the bearing capacity and installation space of the bearing. The larger the number, the wider the bearing width and the relatively higher the bearing capacity. However, the specific width value needs to refer to the bearing specification table. For the 3202 bearing, its width series is 2, which belongs to a relatively narrow width series and is suitable for some equipment with certain limitations on installation space.
The third and fourth digits "02" represent the inner diameter size of the bearing. Here, "02" represents that the inner diameter of the bearing is 15mm. Generally, when the inner diameter of the bearing is less than 20mm, there are special regulations for representing the inner diameter size. "00" means the inner diameter is 10mm, "01" means the inner diameter is 12mm, "02" means the inner diameter is 15mm, and "03" means the inner diameter is 17mm. When the inner diameter is greater than or equal to 20mm, the inner diameter size is usually directly represented by numbers. For example, for the bearing model 3220, its inner diameter is 100mm (20×5 = 100, the inner diameter size is the number multiplied by 5).

Manufacturing Process and Materials

• High-quality Materials: We use high-quality bearing steel to manufacture the 3202 bearing. This kind of bearing steel has extremely high hardness, strength and good wear resistance. It can effectively resist wear, fatigue and other problems that may occur in bearings under high-speed rotation and heavy load, greatly prolonging the service life of the bearing and reducing the maintenance cost and downtime of equipment.
• Advanced Technology: In the manufacturing process, advanced processing technology and a strict quality control system are applied. From the screening of raw materials to the processing of parts, and then to the final assembly and inspection, every link is carefully controlled to ensure that parameters such as the dimensional accuracy, surface quality and internal clearance of the bearing reach extremely high standards, thus ensuring the low-noise and low-vibration operation of the bearing and creating a stable and quiet working environment for the equipment.

Product Application

• Small motor: In small motors, the 3202 bearing can provide precise support for the motor shaft, ensuring stable operation of the motor at high speeds, reducing vibration and noise, and improving the efficiency and service life of the motor.
• Power tools: For power tools such as electric drills and electric saws, the 3202 bearing can withstand the complex loads generated during the operation of the tool, including radial cutting forces and axial thrusts, ensuring the reliability and durability of the tool at high speeds and making the operation more smooth and safe.
• Office equipment: In office equipment such as printers and copiers, the 3202 bearing helps to achieve precise rotation and stable operation of paper transfer components, ensuring that the equipment can complete printing, copying and other tasks efficiently and accurately and reducing the occurrence of paper jams and other failures.
• Household appliances: Household appliances like fans and vacuum cleaners also often use the 3202 bearing. It can provide reliable support for motors and rotating parts, making household appliances run more smoothly and quietly during operation and enhancing the user experience.
