LYC pitch bearings are flagship competitive products in the wind power industry, adopting the advanced three-row cylindrical roller structure that has achieved large-scale mass production and extensive mature application in global large and ultra-large wind turbine projects. Different from traditional ball bearings, the three-row cylindrical roller structure realizes independent bearing and reasonable distribution of axial force, radial force and overturning moment, greatly improving overall bearing rigidity, impact resistance and anti-fatigue performance. This structural design perfectly adapts to the frequent angle adjustment, continuous alternating load and instantaneous strong impact working characteristics of wind turbine blades, effectively solving common problems such as micro-wear and fatigue failure of pitch bearings under long-term variable working conditions. All products undergo strict material screening, precision heat treatment and surface strengthening treatment, with dimensional accuracy and performance indicators fully complying with LYC-led national wind power bearing standards. Applicable to all mainstream wind turbine models on land and offshore, the bearings maintain stable and precise blade angle control, effectively improve wind energy utilization and power generation efficiency, and meet the 25-year long-life design requirements of high-end wind power units.
