Non-standard bearings are non-standard bearings. In popular terms, they are bearings that do not meet the external dimensions specified by national standards, that is, all bearings whose external dimensions are different from national standards.
Its main features are low generality, mostly for special equipment and special occasions, small batches, and trial products of new research and development equipment account for the majority; but due to its non-scale and batch production, there are not many production enterprises and high costs , The price is more expensive.
Non-standard bearings are non-standard non-standard bearings that are not compatible with the standard bearing size structure, that is, bearings produced according to customer requirements. E.g. Non-standard inside and outside 49 standard 50 everything else is the same. Then 49 is a non-standard. You have to follow the size and structure of the client book. Otherwise, you know if 49 is a national standard or 50. Other structures are different.
The non-standard bearings produced by Yuwei Bearing generally include: V-shaped and U-shaped bearing series, full ball bearing series, extended inner ring bearing series, surface coated bearings and non-standard coated bearings, etc.
