The rolling bearings used in traction motors must meet the challenging requirements of reliable operation and long service life. Our company can adopt personalized design concepts for special designs based on actual use needs, and rely on advanced process technology and a complete quality assurance system to ensure that each set of bearings has excellent performance and high reliability. Cylindrical roller bearings and deep groove ball bearings are usually used in traction motors. Single-row cylindrical roller bearings have advantages over other conventional bearings because their inner rings are particularly easy to separate from the roller cage outer ring assembly. This feature is extremely beneficial for the installation, disassembly, maintenance and inspection of bearings. Cylindrical roller bearings are particularly suitable for bearing high radial forces. NJ and NUP cylindrical roller bearings can also bear some axial forces. The modified line contact between the rolling elements and the raceways avoids edge stresses. Their calculated life can usually reach 2 million kilometers due to the following special design.
◆ Special cage design improves friction and running performance
◆ Optimized internal structure design improves load-bearing capacity and reduces friction torque
◆ Optimized design accuracy and internal clearance
◆ Effective insulation
