Since 1997 LYC had begun to research and develop series of bearings used by wind power generators such as pitch bearings yawing bearings main shaft bearings and gear box bearings etc. Those bearings produced by LYC are with high load carrying capacity long using life (20 years) highly reliability excellent antiseptic property and resistant shock ability etc. They can rotate flexibly and stably. LYC has a history of 10 years of manufacturing bearings of wind turbines. LYC is the creator of the standards for wind turbine bearings.
