Product Details

Basic type
- The bearing model 3306 2RS belongs to double row angular contact ball bearings. Double row angular contact ball bearings have two rows of balls and can bear radial and axial loads simultaneously, and can work at a relatively high speed.
Meaning of numbersFor this basic model of 3306:
-
Looking from left to right, the first digit "3" indicates that the type of bearing is a double row angular contact ball bearing.
-
The subsequent "30" indicates the size series. The size series is used to determine the dimensional relationships such as the outer diameter and width of the bearing. Different size series can adapt to different installation spaces and load requirements.
-
The last "06" indicates the inner diameter size of the bearing. The calculation method for the inner diameter is: inner diameter = 06×5 = 30mm (when the inner diameter code is less than 04, inner diameter = inner diameter code ×5).
Suffix meaning"2RS" is a suffix:
-
"2" indicates double row, which corresponds to the "3" (double row angular contact ball bearing) in the previous type code.
-
"RS" indicates that the bearing is equipped with a rubber seal (Rubber Seal). This kind of seal can prevent lubricant leakage and also prevent external contaminants such as dust and moisture from entering the bearing interior, thereby prolonging the service life of the bearing and improving the reliability of the bearing.
So, the 3306 2RS bearing is a double row angular contact ball bearing with an inner diameter of 30mm and equipped with a rubber seal. It can bear radial and axial loads and is suitable for working environments with relatively high speeds.

Strong load-carrying capacity
- As a double-row angular contact ball bearing, 33062rs performs outstandingly in terms of load-carrying capacity. It can handle large radial and axial loads simultaneously. In practical applications, such as in some mechanical transmission systems that need to bear complex forces, it can stably support rotating parts and ensure the normal operation of mechanical devices. For example, in the transmission of a car, it can withstand the radial and axial forces generated during gear transmission, ensuring the smooth operation and precise transmission of the transmission shaft, which helps improve the power transmission efficiency and shifting smoothness of the car.
Adaptable to high speeds
- Its internal ball structure and precise manufacturing process enable 33062rs to adapt to high speeds. In high-speed rotating mechanical devices, such as motors and fans in some industrial equipment, it can maintain low friction and heat generation, reduce energy loss, and still work stably under long-term high-speed operation without failure due to overheating or excessive wear.
Good sealing performance
- The rubber sealing ring mentioned earlier is a major highlight of 33062rs. This sealing design enables the bearing to maintain good performance in harsh working environments. Whether in industrial plants with a lot of dust or in environments with high humidity, it can effectively prevent external pollutants from entering the bearing interior, thereby reducing bearing wear, corrosion and other problems caused by the entry of impurities and ensuring the accuracy and stability of the bearing

Industrial Equipment:
- Pumps: Such as oil pumps, Roots blowers, air compressors, etc. Double-row angular contact ball bearings can withstand the radial and axial loads generated during the operation of pumps, ensuring the stable rotation of pump shafts. The 2RS sealing design can prevent oil or gas leakage and at the same time prevent external impurities from entering the bearing interior.
- Printing Machinery: When printing machinery is working, it requires high-precision transmission and stable operation. This bearing can withstand various loads generated during the printing process and ensure the precise rotation of printing rollers and other components, thereby improving printing quality. Its sealing performance can also effectively prevent ink and other pollutants from entering the bearing and affecting its performance.
Transportation:
-
Automobiles: Can be applied to parts such as the transmission and differential of automobiles. In the transmission, it needs to bear the radial force and axial force generated during gear transmission to ensure the smooth operation and precise transmission of the transmission shaft, which helps improve the power transmission efficiency and shifting smoothness of the automobile; in the differential, it can adapt to the complex stress conditions of the differential pinion shaft under different driving conditions such as turning of the vehicle, so that the vehicle can turn smoothly 56.
-
Motorcycles: Used in components such as the engine and transmission of motorcycles, it can adapt to various loads generated by the engine and transmission system during the driving process of motorcycles and ensure the power transmission and driving stability of motorcycles.
Household Appliances:
- Air Conditioners: Applied in the compressor and fan motor of air conditioners. When the compressor is working, it needs to bear a large pressure and load. This bearing can ensure the stable rotation of the compressor shaft and improve the efficiency and reliability of the compressor; the bearing in the fan motor needs to ensure the stable rotation of the fan blades and provide good ventilation and heat dissipation indoors. The 2RS seal can prevent dust and moisture from entering and extend the service life of the bearing .
Washing Machines: Applied at the motor and drum shaft of washing machines. The bearing in the motor needs to bear the torque and vibration generated when the motor is running to ensure the stable operation of the motor; the bearing at the drum shaft needs to bear the radial and axial loads of the drum during the washing and dehydration processes to ensure the stable rotation of the drum and reduce vibration and noise .
