Main Shaft Bearings

LYC wind turbine main shaft bearings are the core strategic products of domestic wind power bearing localization, holding the largest market share in China with a domestic market occupancy of over 40%, ranking first in the industry for a long time. As the leading drafter of national main shaft bearing standards, LYC has deeply accumulated core technologies in main shaft bearing design, material optimization, precision manufacturing and performance testing. The product series fully covers medium, large and ultra-large power wind turbines from 1.5MW to 20MW+, adapting to double-fed, semi-direct-drive and direct-drive mainstream technical routes. Optimized for the extreme working conditions of long-term heavy load, alternating impact and variable speed operation of wind turbine main shafts, the bearings feature ultra-high load-bearing capacity, excellent low-temperature toughness and long fatigue life. Relying on the industry’s only national key laboratory, all products pass full-scale bench simulation tests and actual wind field verification. The 16MW and 20MW ultra-large offshore main shaft bearings have achieved stable mass production and batch loading, with reliable performance verified by extreme typhoons and harsh marine environments, becoming the most authoritative and trusted domestic replacement product for high-end wind turbine main shaft bearings.
