Oil free bearing (SF-1) is a new type of lubrication bearing which has the characteristics of metal bearing and oil-free bearing. The metal matrix bears the load, and the solid lubrication material with special formula plays the role of lubrication.
It has the characteristics of high bearing capacity, impact resistance, high temperature resistance and strong self-lubricating ability, especially suitable for heavy load and low speed.
When it is difficult to lubricate and form oil film, such as reciprocating or swinging, it is also not afraid of erosion and erosion by water and other acids.
The majority of users generally reflect that inlaid bearing not only saves oil and energy, but also has a longer working life than ordinary sliding bearing.
At present, the products have been widely used in metallurgical continuous casting machine, steel rolling equipment, mining machinery, ships, steam turbines, water turbines, injection molding machines and equipment production lines.
Production technology of oil free bearing
Due to the requirements of production technology, some key equipment of industrial and mining enterprises operate under extremely bad working conditions.
Due to the heavy equipment, high ambient temperature, large dust or acid corrosive gases such as CO and SO2 in the air, there are many problems in the lubrication of the equipment, and the friction and wear are serious.
Most of the domestic enterprises still use the traditional oil and grease lubrication, but in fact, these industrial and mining conditions have exceeded the scope of oil and grease lubrication. It is very easy to bite or bite the bearing and other friction pairs, causing serious parts wear and damage, and often leading to equipment shutdown. In order to produce continuous operation, in addition to the original design requires the installation of multiple sets of equipment, but also a large number of maintenance personnel.
The increase of productivity is seriously restricted. The consumption of spare parts and energy has become an important obstacle to the development of production. Automobile manufacturing, cement production, petrochemical and other enterprises have proposed to provide special lubricating materials under complex working conditions.
Therefore, the research on inlaid self-lubricating composite material highlights its own characteristics in material formula and preparation process, and the material performance has reached the international advanced level, which solves the lubrication problem under special working conditions for enterprises, and brings obvious economic and social benefits.
