Bronze Sintered Parts
Bronze Sintered Parts are used whenever particularly low noise levels are required, loads are variable or little space is available. Bronze Sintered Parts consist of pressed metal powder whose pores are impregnated with a lubricant. The impregnating oil or fluid ensures permanent lubrication of Bronze Sintered Parts . The choice of lubricant depends on the application and has a decisive impact on the function and service life of Bronze Sintered Parts . High temperatures, for example, can easily increase corrosion if the lubricant is not compatible with the Bronze Sintered Parts material. Selection of the right lubricant for your application will also involve the viscosity, compatibility with plastics and seals, reduced start-up wear and thermal behavior.
