Boston, MA – Emerson Bearing, providers of bearings and related products to OEM (original equipment manufacturers) and MRO (maintenance, repair and operations) markets internationally, has created a dedicated Wind Power Generation Division to accommodate the unique bearing requirements of the wind turbine market.

Wind turbines often stand 250 ft in the air and are mechanical and technical marvels that rely on bearings, which are the key components of the gearbox, generator and blade.

Emerson Bearing provides the necessary roller bearings, deep-groove ball bearings and four-point contact bearings for gearboxes.

The generator in the nacelle of a wind turbine is subjected to significantly greater vibration loads than land-based equipment, so bearing size, design and lubrication all play a critical role. The bearing arrangement of a generator generally contains a combination of deep-groove ball bearings or cylindrical roller bearings. Due to the risk of serious damage, such as melt craters and false brinelling, Emerson Bearing advises using current-insulated bearings in many applications.

It is critical that the turbines be aligned optimally to the wind. This is controlled by blade bearings (pitch bearings), yaw bearing and blade adjustment, which requires sealed spherical bushings that have corrosion protection.

Rick Piracini, a marketing specialist and industry expert at Emerson Bearing, oversees the company’s Wind Power Generation division. For more information, visit http://www.emersonbearing.com.
