Protection against electrical erosion
With insulating properties integrated into the bearing, INSOCOAT bearings can improve reliability and increase machine uptime by virtually eliminating the problem of electrical erosion.
High electrical resistance
The aluminium oxide coating provides a minimum electrical resistance of 200 MΩ and can withstand voltages up to 3 000 V DC.
Consistent electrical performance
Plasma-spray coatings are normally hygroscopic and, therefore, vulnerable to penetration caused by condensation. To protect against this effect, INSOCOAT bearings are treated with a unique sealant.

Components of Insocoat Deep Groove Ball Bearings
Outer Ring
The outer ring is the larger of the two rings. There is a groove on the inside diameter of the outer ring that forms a pathway for the balls. The outer ring is usually held stationary.
Inner Ring
The inner ring is the smaller of the two bearing rings. The inner ring has a groove on its outer diameter to form a pathway for the balls. The surface of the outside diameter path is finished to extremely tight tolerances and is honed to a very smooth. The inner ring is mounted on the shaft and it's the rotating element.
Cage
The main purpose of the cage is that it separates the ball, maintaining a constant spacing between the inner and outer rings.
In the automotive industry, these bearings are used in engines, gearboxes, transmissions and wheel hubs to ensure smooth and reliable operation of rotating components.
In the aerospace industry, these bearings are critical for components that must operate under extreme temperature and pressure conditions while ensuring reliability and durability in critical systems such as aircraft engines and navigation equipment.
Household appliances such as washing machines and vacuum cleaners benefit from deep groove bearings because of their ability to operate quietly and with low vibration, improving the user experience and increasing product longevity.
In machine tools, deep groove bearings offer precision and strength, improving the quality of the end product and reducing downtime due to their long life and reliability.

Safety Tips for Using Insocoat Deep Groove Ball Bearings
Keep Bearings and Surrounding Area Clean
Dust, dirt, and debris, even if invisible to the naked eye, have harmful effects on bearings. Prevent the entry of dust and dirt by keeping the bearings and their environment as clean as possible.
Handle Carefully
Heavy shocks during handling may cause bearings to be scratched, dented, or otherwise damaged, possibly resulting in their failure. Excessively strong impacts may cause chips or cracks.
Use Proper Tools
Always use proper and well-maintained equipment when handling bearings and avoid general purpose tools.
Prevent Corrosion
Since perspiration on the hands and various other contaminants may cause corrosion, keep the hands clean when handling bearings and wear gloves if possible. Monitor for rust caused by corrosive gasses or moisture.
