Kaydon marketsRenewable energy—Wind turbinesKaydon is North America's leading supplier of wind turbine bearings, with a 20+ year track record of supplying slewing ring bearings to the renewable energy market. Kaydon's pitch and yaw bearing solutions support critical requirements in a variety of systems, including high and low wind speed; land based or offshore; from 200 kW to 5.0 MW. Four-point and eight-point bearings allow turbine blades to be indexed or positioned to optimize blade angle, depending on wind speed. We apply engineering expertise to best meet critical performance requirements and industry regulations with the most economical design while meeting Germanischer Lloyd and other specifications. Kaydon pitch bearings allow the turbine blade to be indexed or positioned to optimize blade angle, depending on wind speed. Our yaw bearings allow the turbine nacelle to rotate into the wind and support the nacelle on the tower. Kaydon slewing ring bearings for wind turbines feature deep groove gothic arch raceways and maximum ball complement. Integral seals (or non-contact shields, in the case of smaller bearings) assist in the exclusion of contaminants. Kaydon HS, HT, MT and XT series slewing ring bearings feature a four-point contact design that provides exceptional moment, thrust, and radial load capacities. The raceway of the Kaydon KH series four-point contact slewing ring bearings provides four points of contact with the balls, enabling it to carry radial, thrust, and moment loads individually or simultaneously. Kaydon DT series eight point, contact double row ball bearings feature two raceways, located in both the inner and outer rings. This results in a total of eight surfaces the balls may contact at any time, providing exceptional moment, thrust, and radial load capacities. Through precise manufacturing, the raceways are closely matched to provide a high degree of load sharing. Kaydon's experience in wind energy helps customers specify the most appropriate corrosion resistant materials and coatings, including zinc, paint, or other surface treatments, for meeting critical operating temperatures down to -40°C. Unique sealing arrangements are available for severe operating conditions, and Kaydon manufacturing capability accommodates both internal and external gear designs in both hardened and unhardened conditions.
