Better bearings for wind turbines
Electrically insulated bearings prevent damage caused by passage of electric currents through the bearing elements They do so through use of an insulation coating (ceramic oxide) on the outer or inner ring or by using ceramic oxide rolling elements depending on size and type of bearings
Hybrid bearings
Hybrid bearings have rings made of bearing steel and rolling elements made of bearing grade silicon nitride (Si 3 N 4) which make the bearings electrically insulating Silicon nitride rolling elements can extend bearing service life by offering enhanced bearing performance even

Precision Rolling Bearings for Machine Tools MEGAOHMTM
MEGAOHMTM Series Insulated Bearings Bearings used for electric equipment such as motors and generators may cause electrolytic corrosion due to leakage current which shortens the bearing life MEGAOHMTM series insulated bearings are the bearings developed to prevent this electrolytic corrosion The series includes ceramic and resin type bearings
BEARING DAMAGE DUE TO ELECTRIC DISCHARGE
BEARING DAMAGE DUE TO ELECTRIC DISCHARGE ELECTRICAL DISCHARGE MACHINING OF BEARINGS Hugh Boyanton Shaft Grounding Systems Inc Albany OR Abstract The frosted fluted or corrugated pattern often found on the surface of the inner or outer race of an anti-friction bearing is often the result of electrical damage
Shaft Grounding
Shaft Grounding is essential BAC Corrosion Control A/S supplies systems to marked leading companies Let us help you protect your investment! When the propeller shaft is rotating it will be electrically insulated from the hull by the lubricating oil film in the bearings and because of dissimilar materials used for the propeller (bronze) and the hull (steel) they will form a galvanic couple
ELECTRICALLY INSULATED BEARINGS
Cost efficiency due to increased bearing life Special preparation of the housing bore is not required Thermal conductivity between bearing and the housing remains unaffected Electrical Corrosion Applications: Electric Motor Generator Wind Turbine Traction Motor Bearing Type Bearing Bore Code Radial internal Clearance Electrically Insulated
Bearings for wind turbines
May 29 2009For generators insulated bearings include the Megaohm Series These are well insulated against electrical currents Generators often produce stray currents that cause electrolytic corrosion which can shorten bearing life To combat the problem QIBR's ceramic-coated Megaohm ball bearings insulate themselves from electric current
Long Term Storage Procedure
bearings and do not require lubrication during storage periods up to 12 months b Motors with oil lubricated anti-friction bearings are shipped without oil Fill bearing reservoirs to the proper levels as soon as the motor is received and prior to rotating the shaft The oil level is shown on the sight gauge for each bearing oil reservoir

Lubricants
Regardless of the application reliability of the apparatus is dependent upon proper lubrication The primary function of lubrication is to provide a thin film of oil in between the rolling elements and the bearing raceways This film reduces friction between the sliding surfaces and prevents metal to metal contact while protecting the components from oxidization
Bearing analysis: Troubleshoot the problem not the failure
One example is of an electric motor in a paper mill In this case an electrically insulated cylindrical roller bearing NU 322 ECM/C3VL024 is used in an electric motor of a paper winder in the reel section of a tissue paper machine The electric motor speed is variable (400 VAC with frequency converter) and running between 1 000 and 1 500 min-1
