Main features of self-lubricating bearing products

wallpapers News 2020-11-17

The manufacturing technology of self-lubricating bearings originated in Britain. In the 1950s, PTFE (polytetrafluoroethylene) began to be tested as a bearing material in the UK, and the copper powder sintering process also achieved a breakthrough. In 1956, the world\'s first self-lubricating DU bearing lined with PTFE and supported by a steel plate was put on the market. In the late 1960s, self-lubricating bearings began to enter cutting-edge technology applications such as aerospace. Since the 1970s, British self-lubricating bearing manufacturers have licensed their technology to French, German, Japanese and American companies. This move has promoted the rapid development of the world\'s self-lubricating bearing industry, and self-lubricating bearings have gradually entered all mechanical manufacturing fields. The following are some characteristics of self-lubricating bearing products.


Suitable for places where it is impossible or difficult to refuel

Due to the requirements of special production processes, certain key equipment of automobile manufacturing and machinery industry enterprises need to operate under extreme conditions. Due to the heavy equipment, high ambient temperature, large dust in the air or acidic corrosive gases, it is difficult to add lubricating oil to the equipment, so the friction and wear of rolling bearings or ordinary sliding bearings are serious, and bearing bites or bites are prone to occur. Die, causing wear and damage to parts, which leads to equipment shutdown. In order to achieve continuous operation, in addition to the original design requiring the installation of multiple types of space shuttle maintenance equipment, a large amount of maintenance work must be carried out at the same time, which consumes a lot of spare parts and energy. Therefore, companies in the automobile manufacturing, engineering machinery and mold industries all have requirements for special lubricating materials under complex working conditions. No oil can greatly simplify the design and structure of the bearing, reduce costs, save design time, and use the bearing without maintenance or less maintenance, and avoid the risk of insufficient oil supply.

Save a lot of installation and operating costs

Since the self-lubricating bearing does not need an oil supply device, it can save a lot of installation and operation costs, improve mechanical performance, and increase service life and reliability. Oil-free treatment does not require waste oil recycling and treatment, and it is also conducive to environmental protection. Self-lubricating bearings have lower requirements for the hardness of the grinding shaft, thereby reducing the difficulty of processing related parts. In the self-lubricating composite bearing structure, the surface can be electroplated with a variety of metals, which can be used in corrosive media. In addition, since oil-free lubrication does not have the problem of grease volatilization, self-lubricating bearings can be used in high-temperature and high pressure environments.
