History
With 20 years of history, LYXQL started off manufacturing general slewing bearings. Over the years, we've expanded our focus to include large slewing bearings, shrink discs, high-speed couplings, and industrial forgings. Our primary products now encompass wind turbine main bearings, yaw bearings, pitch bearings, marine crane slewing bearings, tunnel boring machine main bearings and components, wind turbine shrink discs, and high-speed couplings. What began as a small, obscure company has grown into a leading name in China's wind turbine bearing industry and a publicly listed company. Here's a glimpse into our journey:
