Basic requirements for bearing material

Basic requirements for bearing material

         Bearing bush is an indispensable part in the mechanical field. Although the bearing bush is a small part, it plays a very important role. On the relevant sales platform, there are many different bearing bushes, the production materials of the bearing bush, and what are the requirements.
1. High compressive strength and fatigue strength
     Bearing pads are often used together with medium-speed and heavy-load bearings with low-speed and heavy-load bearings. Its material needs to have high compressive strength and cannot be damaged quickly during use. The replacement of bearing pads takes a certain amount of time. In terms of material selection, aluminum alloy bearing bushes are mostly used, and they are made of low carbon steel 05, 08, 10, and 15 steel.
2, the coefficient of friction is small
     When the bearing bush is used with the bearing and related equipment, it needs to reduce the friction coefficient to a certain extent, so it needs to have a certain wear resistance, as well as a certain mechanical running-in performance and anti-gluing performance. When in use, in order to reduce friction, a layer of lubricating oil will be added.
3, the coefficient of thermal expansion is small
      The use of mechanical equipment is often in a high temperature environment. In some metals, the thermal expansion coefficient of copper is very stable. Copper alloy is also very suitable as its material, which can be divided into lead bronze and aluminum bronze. , There are three major categories such as tin bronze, and the relevant temperature can be as high as 250 degrees. In medium and low speeds, it can cooperate with the work of related bearings.
4, cost-effective
     The service life of the bearing pad is relatively short, and it is also a kind of consumable. In order to reduce the cost of the user, the manufacture of the bearing pad should meet the requirements of high cost performance.

      As an important spare part of mechanical equipment, the bearing bush is made of raw materials that follow the above four requirements.

      SNW very much welcomes customers to call and email, or leave a message to consult, you can customize the bearing, bearing seat and customized processing metal parts and other products.
