INSOCOAT Bearings / Electrically insulated rolling bearings / VL 0241 series

Current Insulated Bearings

When a stray current in an electric motor uses a bearing as its path to ground, bearing damage can occur. The electric current passing can cause micro cratering in the raceways of inner & outer rings and on the rolling element surface which ultimately changes the structure of the metal.

BMI has collaborated to develop a special ceramic coating using a European “plasma spraying technology” which ensures 100% protection and electric insulation

Electric corrosion causes increased noise levels & vibration and reduced effectiveness of lubricant – drastically decreasing bearing service life.

Once bearing damage from electric corrosion has begun, increased noise levels, reduced effectiveness of lubricant and excessive vibration will drastically decrease bearing service life. “INSUCOAT” To overcome this problem BMI engineers have developed in collaboration with a university a special ceramic coating which ensures 100% protection and electric insulation. The coating is applied using a “plasma spraying technology” from Europe.

The coating can be applied on the inner or outer ring depending upon the application.

Typical Application:

• Traction motor of Railway vehicles
• Electric motors(AC/DC)
• Generators (wind power)
