In the last month. we received a mail from a bicycles factory.
We want a big clearance high speed 6205 2RSR deep groove ball bearing ! can you recommend and produce it for me? 6205 2RSR C2 is good, but 6205 2RSR C3 is available?
The difference between C3 clearance bearings and C2 bearings is mainly reflected in radial clearance, but there are also some differences in inner diameter deviation between the two. Specifically, the radial clearance of C3 clearance bearings is larger than that of C2 bearings. C2 bearings belong to the type of bearings with small clearance and are suitable for applications that require high precision. C3 clearance bearings are more suitable for applications that are sensitive to speed and have high environmental vibrations, in order to reduce wear and maintain smooth operation. In addition, due to the large clearance of C3 clearance bearings, they can also accommodate a certain amount of axial displacement, which is very beneficial for certain specific applications.
In terms of inner diameter deviation, although both C2 and C3 bearings follow the same international standards, the inner diameter deviation of C2 bearings is usually smaller than that of C3 bearings. This means that under the same conditions, C2 bearings can provide a tighter fit and higher rotational accuracy. However, this does not mean that C2 bearings are superior to C3 bearings in all cases. In practical applications, the choice of type of bearing depends on specific working conditions and performance requirements.
You prefer 6205 2RSR C2 bearing or 6205 2RSR C3 bearing

A few days later. We get the reply from our customer---we prefer 6205 2RSR C3 bearing. but can you support the hybrid ceramic material, such as Si3N4 ceramic ball.PTFE or nylon retainers would be best, but steel will work also. The races can be chromium or stainless steel. My ultimate goal is to have the lowest rolling resistance possible. These will be used as high performance upgrade bearings for bicycles, so they don't have to spin very fast, just have low resistance to improve efficiency. Are you able to make any recommendations or help?
Sure. the material you mentioned all available here. We'd like to send you some 6205 2RSR C3 bearing sample with different material for you test at first.
After you confirm which material 6205 2RSR C3 bearing you prefer. You can play the bulk order.
The 6205 2RSR C3 bearing sample have arrived our customer countr. A tes is currently in progress.
Any type bearings you need. Feel free to contact me for more details!
