            NTB-50-3 固體鑲嵌潤滑軸承 / Solid-lubricant-Embedded
            NTB-50-3 Series
            Substrate characteristics
            In the high-quality carbon steel casting surface high-strength copper alloy as the base material of the bearing, this manufacturing process makes the combination of copper and steel surfaces to achieve complete metallurgical bond, reducing the material costs but also improve its carrying capacity; and according to the use of labor condition in which the solid lubricant Face mosaic greatly reduces the coefficient of friction reaches a self-bearing and lubrication purposes.
