Comparison and assembly case analysis of bearing 6200ZZ with international major brands.
6200ZZ and 2RS are representative models of the deep groove ball bearing 6200 series, with an inner diameter of 10MM, an outer diameter of 30MM, and a width of 9MM
Each bearing manufacturer has a model number of 6200ZZ. Is the naming of these models consistent and can they be used interchangeably? This article will answer each question for you.
The following table compares the 6200ZZ produced by BLH Bearing Factory with the same model of international mainstream brands:

Answers to common questions about bearing 6200ZZ
Q: What is the difference between bearings 6200ZZ and 6200-2Z?
Answer: The only difference is the labeling of different brand factories. The structure and size are the same, both are double-sided metal dust covers.
Q: Can bearings 6200ZZ and 6200-2RS be interchangeable?
Answer: These two models have the same size, but the sealing structure is different. They should be exchanged carefully. ZZ is a metal non-contact dust cover, and 2RS is a contact rubber dust cover. Rubber dust covers have better waterproof and dustproof performance. ZZ metal dust cover is more suitable for high-speed applications.
Q: Is there a significant difference in rotational speed between the 6200ZZ grease lubricated and oil lubricated bearings?
Answer: There is a big difference. The grease lubrication speed of the bearing 6200ZZ is 25000 RPM, while the oil lubrication speed can reach 30000 RPM. Oil lubrication has better heat dissipation and is more suitable for high-speed applications.
Q: Can the deep groove ball bearing 6200ZZ withstand axial forces?
Answer: All commonly used deep groove ball bearing models are mainly designed for radial loads and can only withstand very small axial loads. If you want to install them in axial load applications, please contact the engineers at BLH Bearing Factory. We will specifically design a structure and installation plan for axial stress for you.
The following is a case analysis of bearing abnormal noise caused by incorrect installation of 6200ZZ
"Hi Jack, come take a look at my bearings. Why is the noise so loud? The bearings are smoking when they rotate. "
On the last working day of 2025, I received an emergency call from a customer. Without much thought, I told the customer to stop the machine and wait for us to analyze the cause on site.
When we quickly arrived at the scene, we found that the customer's bearing application emitted a burning smell, which was very dangerous. Through on-site inspection and customer installation status. We have identified the cause of the bearing damage.
"Why doesn't this bearing have a dust cover?"
"Oh, Jack, the situation is like this. When installing the 6200ZZ bearing, our installation fixture was severely worn, so I increased the air pressure a bit. After the air pressure increases, it causes friction between the installation fixture and the dust cover of the bearing, resulting in some deformation of the dust cover. "
"Then you removed the deformed metal dust cover, right?"
"Yes, Jack, you guessed it right"
"It was you who removed the dust cover of the bearing that caused the loss of lubricating grease and the entry of dust impurities into the interior of the bearing. Most importantly, when you removed the dust cover, you accidentally damaged the bearing retainer, causing friction during the rotation of the bearing and resulting in such loud noise. The dust impurities that entered the interior of the bearing quickly rubbed against the bearing without lubricating grease, causing high-temperature carbonization and the smell of burning"
"Oh, I understand. Thank you, Jack"
This case is a typical case of bearing damage caused by improper installation, and the installation personnel did not replace the new installation fixture, but instead adjusted the atmospheric pressure, resulting in damage to the shaft before removing the dust cover. A series of erroneous operations led to this tragedy.
The correct approach is:
1. Replace damaged installation fixtures;
2. Set the appropriate air pressure; (Ensure that the dust cover of the bearing is not damaged during installation)
3. Provide installation training to installation personnel to avoid similar errors in the future.
