Bearings are an indispensable key component in mechanical equipment, and the query of their model and size is crucial for practitioners and users in the bearing industry.

1. What is a bearing model and size query table?

A bearing model and size query table is a table or database that records various bearing models and size parameters. By querying the data in the table, users can quickly and accurately find the model and size information of the required bearing.

2. What is the structure and content of the query table?

Usually, the bearing model and size query table contains the following information:

- Bearing model: records the model codes of various bearings, such as the 600 series of deep groove ball bearings and the 30000 series of tapered roller bearings.

- Inner diameter (d): indicates the diameter of the inner ring of the bearing, usually in millimeters (mm).

- Outer diameter (D): indicates the diameter of the outer ring of the bearing, also in millimeters.

- Width (B): indicates the width of the bearing, also in millimeters.

- Weight: records the weight of the bearing, in kilograms (kg).

3. How to use the bearing model size query table?

When using the bearing model size query table, users can follow the following steps:

- Determine the type of bearing required, such as deep groove ball bearings, tapered roller bearings, etc.

- Find the corresponding range or specific value based on the bearing's inner diameter, outer diameter or width and other size parameters.

- Find the bearing model that meets the conditions in the query table and obtain the corresponding size information.

Content analysis and explanation of the bearing model size query table

1. Coding rules for bearing models

Bearing models are usually composed of letters and numbers, and different letters and numbers represent different meanings. For example, in the model of a deep groove ball bearing, the first digit indicates the bearing type, the second digit indicates the bearing series, and the following digits indicate the specific size.

2. The importance of size parameters

The size parameters of the bearing directly affect its applicable range and working performance. The inner diameter determines the installation method of the bearing and the diameter of the applicable shaft, while the outer diameter and width determine the outer dimensions and load-bearing capacity of the bearing. Therefore, when selecting a bearing, it is necessary to reasonably select the appropriate size parameters according to the actual working conditions and requirements.

3. Update and maintenance of query tables

With the development of the bearing industry and the advancement of technology, new types of bearings are constantly emerging and their size parameters are constantly being updated. Therefore, the bearing model size query table needs to be updated and maintained regularly to ensure that the data therein is accurate and reliable.

1. Application of bearing model size query software

In addition to traditional query tables, modern technology also provides the application of bearing model size query software. These software usually have more powerful query functions and richer data resources, which can meet more complex query needs.

2. Standardization of bearing model size

In order to facilitate user query and use, bearing model size has been standardized by the International Organization for Standardization. For example, the ISO 15 standard specifies the series and size range of the inner diameter, outer diameter and width of various bearings, providing users with more convenient query and selection.

3. The relationship between bearing model size and bearing performance

Bearing model size is not just a combination of a string of numbers and letters, but contains rich bearing performance information behind them. By deeply understanding the relationship between bearing model size and bearing performance, users can better select and apply bearings and improve the reliability and efficiency of equipment.

The bearing model and size query table is an indispensable tool in the bearing industry. Through the query table, users can quickly and accurately find the model and size information of the required bearing.
