Product description

Self-lubricating graphite bearings have become irreplaceable components in extreme working conditions such as high temperature, corrosion, and vacuum due to their excellent performance. They are mainly reflected in the following fields:
1. High-temperature industrial equipment
Self-lubricating graphite bearings do not require external lubrication during application, thus avoiding the failure of grease carbonization at high temperature. In addition, since the melting point of graphite is as high as 3000℃, graphite bearings can withstand instantaneous high temperatures of 1200℃, and their life is longer than that of traditional metal bearings. Graphite bearings are usually used in metallurgical continuous casting machine rollers, glass melting furnace conveying systems, and ceramic sintering kilns.
2. Vacuum and clean environment
Self-lubricating graphite bearings have zero grease volatilization in applications, meet ultra-high vacuum requirements, and can avoid contaminating precision components. They are often used in semiconductor coating equipment, mechanical parts of spacecraft vacuum cabins, and medical sterilization equipment.
3. Strong corrosive medium environment
Self-lubricating graphite bearings are resistant to acid and alkali corrosion and are more durable than stainless steel bearings. Therefore, they are often used in chemical pumps and valves, nuclear waste treatment equipment, electroplating production lines, etc.
4. Extreme loads and low-quality working conditions
Self-lubricating graphite bearings have a low friction coefficient, low wear under low-speed and heavy-load conditions, and can reduce the frequency of downtime maintenance. Therefore, they are widely used in hydropower station valve hoists, mining crusher spindles, etc.
In summary, self-lubricating graphite bearings are widely used. They are used in various mechanical equipment to reduce direct metal contact and reduce wear between components; their excellent thermal stability enables them to quickly extract friction heat and avoid local overheating and jamming.
