We specialize in the production of solid inlay self-lubricating bearings, graphite bronze bushings, and can customize production in various forms and standards according to customer needs. We have built a complete and scientific quality management system; we have perfect quality inspection systems such as composition testing and mechanical property testing to provide you with high quality products.
Graphite thrust bushing, also known as self-lubricating bearings, is a product with self-lubricating properties in the thrust bushing as the metal matrix of the friction surface to develop an orderly arrangement, the appropriate size of the hole, and embedded graphite or molybdenum disulfide, etc. as a solid lubricant.
The general solid lubricant accounts for 20-30% of the friction surface area. The lubrication principle of this self-lubricating bearing is that during the sliding friction between the shaft and the bearing, a part of the graphite particles is transferred to the friction surface of the shaft and the bearing, forming a more stable solid lubrication diaphragm to prevent the direct adhesive wear of the shaft and the bearing.
This rational combination integrates the respective performance advantages of metal alloy and non-metallic wear reducing material to complement each other, that is, with the high load-bearing capacity of metal and the lubricating performance of wear reducing material. Therefore, it is especially suitable for the environment of no oil, less oil, high temperature, high load or water, etc.
At present, graphite bronze bush has been widely used in engineering machinery, metallurgical machinery, mining machinery, locomotive support, rolling equipment, marine machinery, mold equipment, textile machinery, gas turbines and other low-speed heavy load, high-speed light load and other occasions to use.
There are two basic forms of graphite bronze bushings marked in the national standard: straight column type self-lubricating bronze bushings and self-lubricating graphite bushings with retaining edges. Straight column self-lubricating bronze bush type said: integral inlay bearing, with a baffle edge self-lubricating bush type said: with a baffle edge integral inlay bearing; Folio type self-lubricating bush said: split inlay bearing. With this process also derived from self-lubricating thrust shim and self-lubricating guide plate and other products.
Graphite thrust bushing and bearing commonly used lubricating materials：Solid lubricating materials generally have polytetrafluoroethylene, high-purity graphite or add molybdenum disulfide, zinc stearate material (part of the material can be oiled state).
