NTB-30 耐高温高压无给油轴承 / Self-lubricating Bearing
NTB-30 Series
Substrate characteristics
Apply to the oil,fuel or high-temperature work more difficult part,wear resistance,low coefficient of friction,long life;good perfromance,low noise,no pollution,good corrosion resistance;in operation since the formation of eransfer film to protect the shaft,the role of non-bite-axis phenomenon;low processing requirements of the shaft to teduce processing costs for users;as NTB-30 work surface with special materials,so the NTB-30 has good high temperature and high wear resistance.
