Power Generation

Power generation requires uninterrupted bearing service. The ball and roller bearings for the pumps, compressors, electric motors and drives must meet critical internal clearances, cage designs and Abec precision class. Pillow Block bearings have to be a design that allows for easy and prompt replacement.

Wind Turbines/Harnessing the Wind

The centuries old dream of harnessing the wind efficiently is now a reality. The Wind turbines of today often stand 250 feet in the air and are mechanical and technical marvels that rely on bearings in their key components:

Generator

A generator operating in the nacelle of a wind turbine is subjected to significantly greater vibration loads than its counterpart on the ground. This additional permanent load has a negative influence on the cages and places a strain on the lubricant.

In the design of bearings for a generator, it is not only the size and design that play an important role. Special attention must be paid to the lubrication and protection against possible current passage.

The bearing arrangement of a generator generally contains a combination of deep groove ball bearings or cylindrical roller bearings.The passage of current in a wind turbine generator can cause serious damage to the raceways of bearings in the form of melt craters and false brinelling. It is advised to use current insulated bearings in many applications.
