JFB solid lubricated bronze bearing is a new product with solid lubricant inlay on high force brass substrate. The Ptfe plugged bronze bushings break through the limitation of general bearing relying on oil film lubrication. The Teflon bronze bushings are Suitable for high temperature and suitable for high temperature, high load, underwater operation, corrosion resistance, or can not be refueled, and other conditions. The cast bronze bushings hardness is twice as high as the general copper bush, and its wear resistance is also twice as high. At present, the PTFE plugged bronze bushings product is widely used in metallurgical continuous casting machines, rolling equipment, mining machinery, ships, steam turbines, injection molding machines, and production lines.
