1、 What is a thin-walled bearing with equal cross-section?

Equal section thin-walled bearings are a type of bearing with special section width and thickness, and the same section size can match multiple different bearing inner diameters. Compared to standard bearings, the width and thickness increase proportionally as the inner diameter of the bearing increases, while thin-walled bearings with equal cross-section increase the inner diameter without changing the cross-sectional size.

2、 What are the excellent characteristics of thin-walled bearings with equal cross-section?

1. Compared to ordinary bearings, thin-walled bearings have the advantages of light weight, thin wall thickness, and small size, making them very suitable for situations with strict installation space requirements, and have incomparable advantages compared to ordinary bearings.

2. Due to the thin-walled structure of both the outer and inner rings of thin-walled bearings, they are particularly suitable for use at high speeds, under high loads, and with impact vibrations due to their small inertia, smooth motion, and high self-lubricating performance during rotation.

3. Equal section thin-walled bearings are different from standard bearings in that the cross-sectional area does not change with the increase of inner and outer diameter dimensions in the same series; Adopting thin-walled equal section bearings of the same series can lead to the serialization and standardization of related parts.

4. Equal cross-section thin-walled bearings have the advantages of small volume, light weight, low friction, and high rotational accuracy. This form can reduce the overall size of the equipment without affecting the service life of the bearings, thereby reducing production costs.

3、 Application scenarios of thin-walled bearings with equal cross-section

Equal cross-section thin-walled bearings can provide high load-bearing capacity in applications and are currently the most widely used form of bearing. Due to the uniform cross-section characteristics and large load-bearing capacity of bearings, thin-walled bearings with uniform cross-section are widely used in the fields of automobiles, engineering machinery, rail transit (subways, etc.), aerospace, textile machinery, petrochemical, mining machinery, and precision machining.

For example, the NASA satellite developed by NASA uses two types of thin-walled bearings with different diameters in orbit, one of which uses this type of thin-walled bearing as its key component. It is understood that China has also adopted key components and related technologies similar to equal cross-section thin-walled bearings in the field of aerospace engineering, such as the Shenzhou series spacecraft, the Long March series rockets, various types of military transport aircraft, and various aviation engines. According to experts, with the development of science and technology, the demand for related technological products in China will also increase.

4、 Varieties of equal cross-section thin-walled bearings

At present, the equal section bearing products on the market can be divided into seven open series and five sealed series. The inner diameter ranges from 1 inch to 40 inches, and the cross-sectional dimensions range from 0.1875 "X0.1875" to 1.000 "X1.000". There are three types of open series: radial contact (C-type), angular contact (A-type), and four point contact (X-type). There are two types of sealed bearings: radial contact (C-type) and four point contact (X-type). The materials include copper, stainless steel, alloy steel, etc.
