What are the load-bearing capacity and various strength indicators improved by bimetallic sliding bearings?

Bimetallic sliding bearing material is a composite bearing material composed of multiple layers of metals. This material uses steel lining as the base layer of the bearing material, which gives the bearing high structural strength. The material of the anti friction self-lubricating layer is composed of copper based bearing alloy. It not only does not damage the bimetallic bearing to the dual, but also can withstand some extreme working conditions of high and low temperature plastic shaft sleeve degree.

When friction is accompanied by relative motion, solid lubricants form a lubricating film on the friction surface to prevent contact between metals, thereby reducing the coefficient of friction and improving the bearing capacity. Bimetallic sliding bearing materials are suitable for composite bushings, which are used under special working conditions such as heavy loads, high and low temperatures, vacuum, water vapor, inconvenient addition of lubricating oil, high dust, and impact that are not easy to form an oil film.

It has a reasonable structure, high load-bearing capacity, and good dry running performance and fatigue resistance. Bimetallic sliding bearing material products and their main technical parameters. Comprehensive bearing performance of bimetallic sliding bearing materials:

1. High load-bearing capacity and fatigue strength;

2. The excellent friction and wear performance of copper bearing alloy does not damage the dual structure;

3. High mechanical strength;

4. With the soaring price of copper, significant cost savings can be achieved;

5. Very low friction coefficient, wear-resistant, and long service life;

6. Due to the use of lubricants for lubrication, the dry running performance is good, without sticking or jamming, greatly improving the lubrication effect;

7. Saving oil and other resources has changed the environmental pollution caused by traditional lubrication methods.

Performance parameters of bimetallic sliding bearing material:

1. The friction coefficient is 0.09-0.20;

2. Alloy specific pressure greater than 350 kg/cm2~400 kg/cm2;

3. The linear speed is greater than 6 meters per second to 9 meters per second, and the working temperature is between -200 ℃ and+250 ℃.
