              NTB-40 铜基卷制轴承 / Bronze Self-lubricating Bearing
              NTB-40 Series
              Substrate characteristics
              The bronze bushings as CuSn8 for the substrate has made of a high wear resistance good economic bearing.Standard NTB-40 product dissatisfaction rules diamond work surface oil hole or perforation oil eye,played the role of oil or fuel in the initial movement to form a film easier to reduce the initial friction coefficient.The main use of agricultural machinery,construction machinery where high load low speed.
