Do you Know Non electric Bearing-insulation Bearings?

Non electric bearing uses special spraying process.To spray high -quality membrane on the bearing.
The coater of the membrane and the matrix is strong, and the insulation performance is good.Which can avoid the induction current. Prevent the damage caused by current.And lubricating fat, rolling bodies, and rolling roads. Also improve the service life of the bearings. In insulation bearing, there is a layer of 100 μm thick coating on the surface.Might on outer or inner ring. The adhesion is extremely strong.And further treatment, it can not be affected by moisture and humidity.

Advantages of non electric bearing:
Non electric bearing can avoid damage caused by electric corrosion

it is cost benefits and reliability. The shape size and basic technical characteristics of the insulation bearing are the same.So it can be performed 100 %. Suitable for motor, generator, especially in frequency conversion motor applications.

Type of non electric bearing:

Electric insulation deep groove ball bearings
Electric inspection angle contact ball bearings
Electric insulation cylindrical roller bearings
Inner ring or outer ring insulation bearing with oxide plating layer
Mixed bearing with electrical insulation ceramic roller

Measures to block axis current -use non electric bearing
In order to avoid damage on bearings,measures should be taken to separate current.
For large motors,use independent bearing seats at both ends, they isolation pads made of insulating materials between seat and metal base. For motors that are assembled into a unit of bearings and cases,  usually used at one end (often arranged at non -main shaft extension). For occasions that require higher, the insulation bearing is installed at both ends.

In order to ensure the insulation performance.Which contains the insulation resistance, bearing voltage and axial current. Among them, the purpose of the axis voltage of the motor is:to understand the size of current.The purpose of determining the axis current is:to directly get the value of the bearing current.
Because the damage of the current mainly occurs in the electric motor. Therefore, this inspection generally only uses these types of motor at the initial testing.And of the initial trial production.Or even the use of motor that the axial current found on the bearing during the use.
