NTN has been servicing the Wind Energy industry in Asia, Europe and the United States for many years. NTN’s wide range of product offerings coupled with our unique relationships with major wind turbine manufacturers, puts us in prime position to service your wind-gearbox bearing needs.

As an essential part of the nacelle, the gearbox must function at peak performance to turn wind into power. When replacement is necessary, NTN tapered and cylindrical bearings are designed to reduce downtime with their easy assembly. Specialized designs allow for both high speed and high load carrying capabilities while maintaining a high level of reliability.

NTN bearings can be found in all gearbox applications. From low speed and high speed planetary gear drives in main gearboxes to high speed gear and output shafts, our sophisticated designs can meet your requirements.

In addition to standard cylindrical roller bearings, NTN has developed technology that combines the high load capacity of a full complement bearing with the high rotational speed capabilities of a caged design. Placing the rolling element separator between the rollers, the high capacity cylindrical roller bearing attained a rated life 1.5 times longer than a conventional bearing.

A world leader in tapered roller bearings, NTN’s world-class quality and experience along with its unmatched product offerings of both metric and inch sizes assures complete coverage in wind turbine gearbox applications.

Yaw gearboxes are generally small and are capable of conveying large amounts of torque so the bearings used must be compact and have high load capacities. NTN’s vast product portfolio has all applications covered with angular contact ball bearings.
