Introduction

When buying and selling goods, electronic media are used more and more widely. It has also been applied to the rolling bearing industry, and it is expected to

Most of the later sales will be conducted through electronic media.

When ordering bearings, you may encounter a problem, that is, the code problem, especially those of special purpose and modified products.

Suppliers are different from each other. Therefore, for electronic media business, it is necessary to provide customers and distributors with an unknown bearing code.

In this case, the applicable system of the bearing can be quickly and easily identified.

This can be achieved by using a computerized query structure. The user only needs to input some specified relevant bearings on the computer screen

Simple options (size, number of rolling elements, cage, etc.), if necessary, can also be options related to performance indicators and other characteristics. root

According to these input data, the computer will provide possible bearing code and other information.

In order to simplify the procedure and provide users with a unified input vocabulary, which has nothing to do with the supplier, this standard is a standardized electronic medium.

The body query structure provides special vocabulary used to identify bearings, bearing parts and accessories, which are based on ISO 5593 and other rolling shafts

Bearing standards.

When bearing manufacturers and/or distributors establish their own query structure, in order to filter the bearing codes that meet the requirements of the purchaser, certain shafts

Contract manufacturers and distributors will customize some characteristics or value ranges. At this time, it is recommended to use ISO 5593 and other applicable rolling bearing standards.

terms of.

This standard uses metric units, but the characteristics are also applicable to products with inch sizes.
