[Formed specially designed copper layer using the same copper powder or lower torque than the bronze bearing NTN Corporation (NTN) has developed a CL BEARPHITE * ", with the same or better sintered bronze bearing sliding excellent performanceadding a small amount of a unique copper powder, on the surface of the iron sintered material to form a widely used in the copper layer is a sintered bearing ships automobiles and office equipment, and the classification of the bearing material for the iron group or bronze matrix. Sliding bearing applications, requires a high level of performance, including automotive electrical components, such as power windows and the fan motor, or a copier or laser printer, bronze material. In recent years, with the increase in the price of copper, there has been a greater demand for, can be used as instead of the bronze bearing,, and NTN began to develop a new material made ??of a material sintered bearings, the newly developed BEARPHITE CL "is the unique copper powder, and the material composition, to form a specially designed bearing surface of the copper layer on the same or better sliding properties than the the bronze bearing a small amount of iron-base sintered bearing. As an iron-based bearings, bearings with higher material strength than the bronze bearings, and excellent abrasion resistance. The NTN has started bearing automotive electrical components and office equipment manufacturers, and the target market Bearings extensively in the automotive and industrial sectors. * CL: copper layer abbreviations.
