In the field of mechanical engineering, bearings are key components whose main function is to support and guide the rotating shaft for accurate movement. The protective cover of the bearing also plays a vital role. It can prevent dust, moisture and other contaminants from entering the bearing and extend the service life of the bearing. This article will introduce the application of rubber-covered bearings and iron-covered bearings in different fields in detail.

First, let's take a look at the application of rubber-covered bearings. This type of bearing is usually used in applications that require low friction, high-speed rotation, high precision and high environmental cleanliness. For example, crankshaft bearings in automobile engines require rubber-covered bearings because they can withstand the challenges of high temperature, high pressure and high-speed rotation while maintaining good lubrication performance. In addition, rubber-covered bearings are also widely used in industrial fields such as food processing equipment, medical equipment, and office equipment, which require high operating speeds but cannot generate excessive noise and heat.

Then, let's explore the application scenarios of iron-covered bearings. Compared with rubber-covered bearings, iron-covered bearings are more suitable for applications with harsh environments, heavy loads, and long service life requirements. For example, in heavy machinery and equipment, such as excavators and cranes, iron cap bearings are a common choice. They have high hardness, good wear resistance and corrosion resistance, and can work stably for a long time in harsh working environments. In addition, iron cap bearings are also widely used in aviation, aerospace and other fields, because these fields have extremely high requirements for the accuracy and reliability of bearings.

In general, both rubber cap bearings and iron cap bearings have their unique advantages and applicable scenarios. Which type of bearing to choose often depends on the specific application needs and technical requirements. Understanding the differences and characteristics of these two types of bearings can help us make more appropriate choices in actual work.
