Electrically Insulated Deep Groove Ball Bearings

Send Inquiry

Insulated bearings are a general term for bearings that can prevent the passage of electric current and have insulating properties.

One of the main features of insulating bearings is that there is a 50-200μm thick ceramic coating on the surface, which is responsible for electrical insulation and can resist electrical sparks generated at a voltage of 1000V. Thicker coatings can resist high-voltage discharges above 1000V.

The Importance of Electrical Insulation in Bearings

Bearings play an important role in motors and other rotating equipment. The importance of electrical insulation of bearings is mainly reflected in the prevention of galvanic corrosion of the current on the bearings, to protect the grease and rolling elements and raceways from damage, and to achieve the role of improving the service life of bearings.

Common Applications of Insulated Bearings

Insulated bearings have a very wide range of applications. The continuous development of various industries, including the power industry, railroad facilities, machinery and metallurgical industry, mining and petrochemical industry, etc., all reflect the importance of insulated bearings.

Types of Insulated Bearings

Insulated bearings can be classified into various types according to the type, such as ceramic insulated bearings, hybrid bearings with silicon nitride balls, coated insulated bearings, oil-lubricated insulated bearings, insulated roller bearings, frequency converter grade insulated bearings and so on. Different types of insulated bearings have different characteristics and application scenarios.
