F0512003 ULZ 360390 172050FB Sliding bearing

• Sliding bearings are used as key transmission components in high-speed wire mills, and their design needs to balance stability under high-speed operation and reliability under heavy load conditions. Adopting a dual working face symmetrical layout, with symmetrical oil inlet holes, axial oil discharge grooves, and circumferential sealing edges on both sides, the double bearing area is achieved by optimizing the oil film distribution, significantly improving the service life of the liner. Select aluminum bronze ZCuAl10Fe3 or tin antimony bearing alloy ZSnSb11Cu6, with a surface coating of 0.05-0.1mm Babbitt alloy layer, and a hardness controlled at HB140-160 to balance wear resistance and anti bite performance. The symmetrical oil film structure improves the uniformity of axial load distribution by more than 40%, and the theoretical lifespan can reach 8000-10000 hours. T
