Advantages

Modern design is generating huge demand for today's self-lubricating bearing materials. Even under severe extreme operating environments and maximum load conditions, maintenance-free is required. As cost requirements continue to increase, the reliability requirements of equipment and plant operations are also increasing. Metal self-lubricating bearings can meet maintenance-free and self-lubricating under long-term use conditions, thereby making it possible to design reliable long-term self-lubricating systems. Metal self-lubricating bearing materials can be widely used in rotation, swing and linear reciprocating motion under high load and low speed conditions, and are also suitable for occasions where traditional lubrication cannot be achieved or are prohibited, or in special working conditions such as dust and impact Long-term and stable use under load or irradiation.
