Bearings are essential transmission parts in the operation of mechanical equipment. They are often used in exposed environments and are prone to accumulate dust and foreign matter, affecting bearing performance. However, sealed bearings such as harmonic reducer bearings can solve this problem well, but are these bearings well sealed?

How is the sealing performance of harmonic reducer bearings?
Under normal circumstances, the sealing performance of harmonic reducer bearing is quite good. During the design, a sealing component was added to this bearing. Even in an environment with impurities such as dust and moisture, the good sealing performance of the harmonic reducer bearing can effectively prevent impurities from entering the bearing, ensuring the normal operation of the harmonic reducer and effectively extending the service life of the equipment.
If you want to enhance the bearing sealing performance of the harmonic reducer, you can also choose an oil seal with a dustproof device, which can prevent pollutants, dust, moisture, etc. from entering the sealing cavity from the air side . Especially in the case of serious intrusion of pollutants, you can consider installing two oil seals in series to further enhance the bearing sealing capacity of the harmonic reducer.
It should be noted that the operating temperature range of the oil seal is closely related to the material used. Exceeding the allowable temperature will cause the sealing components to harden prematurely and permanently, increasing wear. Therefore, the bearings of the harmonic reducer are not suitable for use under high temperature conditions.
What are the features of the application ?
As a bearing product commonly used in industrial robot equipment, harmonic reducer bearings have distinct characteristics, which are also the reasons why they are better than general bearings:
1. Compact structure and good sealing. The sealing requirements were taken into consideration at the beginning of the design. The internal structure of this bearing is compact, which reduces unnecessary space and gives the bearing good sealing performance.
2. With stronger load-bearing capacity, the harmonic reducer bearings can withstand loads in multiple directions, including axial loads, radial loads and overturning moments, etc. This not only has a wide range of uses, but also reflects good sealing performance to a certain extent.
3. High precision, small backlash, and relatively large rotation. This type of bearing has a wide range of applications. It has its own mounting holes, which makes it easier to install and will also be much more convenient to adjust later.
4. The harmonic reducer bearings are small in size, light in weight, have smooth transmission, low noise, good rotation smoothness , high working efficiency and large load-bearing capacity.
