Is the bearing standard?

If you have a little contact with mechanical or automotive related knowledge, you may have a big doubt: "Are bearings not standard parts?" This question sounds simple, but behind it lies some "hardcore" knowledge that you may not know.

First of all, the conclusion is that the bearing is a standard part, but the standard is not static.

Most bearings are produced in accordance with international standards (such as ISO standards) or national standards. This means that you can find matching replacements all over the world. Having said that, many times it takes some effort to change a bearing.

This is because, although bearings do have standards to follow in size, material and model, the requirements for bearings in different applications may be completely different. Design more suitable bearings for specific application environments. This has the advantage of maximizing the efficiency and longevity of the device, but the disadvantage is that it is more cumbersome to replace, especially for those niche models.

As a non-professional, you may also need to know some basic "pit avoidance" techniques. First of all, we must choose a source bearing manufacturer with quality assurance to avoid uneven bearing quality. Secondly, when confirming the model, it is best to purchase it against the instruction manual of the equipment to avoid the trouble caused by the mismatch of the model. Finally, it is important not to ignore small problems with bearings. Regular inspection and maintenance of bearings can effectively extend the life of equipment and reduce maintenance and replacement costs.

Although bearings are standard parts, there are many subtle differences in specific applications. Standards are evolving and the need for customization is growing, so it is important to be careful when selecting and using them in accordance with the actual situation.
