Nonstandard Customised Bronze Sliding Bearing Bush In Metallurgical Industry

Product description

The bearing bush is the contact part between the sliding bearing and the shaft, which is very smooth. It is generally made of aluminum bronze, tin bronze, brass, antifriction alloy and other wear-resistant materials. In special cases, it can be made of wood, plastic or rubber. Also known as "bushing", the shape of the semi-circular copper braring .

copper braring has excellent mechanical and physical properties. It can have various comprehensive properties of strength, hardness and toughness. It can also have one or more special properties, such as wear resistance, high and low temperature resistance, corrosion resistance, etc

The main failure forms of bearing shells are wear and gluing. When the strength is insufficient, fatigue failure may also occur. The main requirements for bearing materials are:

① good antifriction and wear resistance;

② sufficient compressive, impact and fatigue strength properties;

③ good compliance, embedment, running in and lubrication;

④ good thermal conductivity, small linear expansion coefficient, good technology, etc.

Self lubricating bearing bush series

1. No oil lubrication or less oil lubrication, suitable for places where oil can not be added or it is very difficult to add oil. It can be used without maintenance or less maintenance.

2. Good wear resistance, small friction coefficient and long service life.

3. It can distribute the stress on a wide contact surface and improve the bearing capacity.

4. The static and dynamic friction coefficients are similar, which can eliminate the creeping at low speed and ensure the working accuracy of the machine.

5. It can reduce vibration, noise, pollution and improve working conditions.

6. In the process of operation, it can form a transfer film, which plays a role in protecting the grinding shaft and has no shaft biting phenomenon.

7. The hardness of the grinding shaft is low, and the shaft without quenching and tempering treatment can be used, thus reducing the machining difficulty of related parts.

8. Thin wall structure, light weight, can reduce mechanical volume

The main forms of bearing bush casting are sand casting, metal casting and centrifugal casting. The main materials of copper sleeve and tile produced by our factory are brass, high-strength brass, aluminum bronze, tin bronze and other non-ferrous metals. The specific models are as follows:
