Insulated Bearings 6320/C3VL0241 for Traction Motors"

Insulated bearings provided by EASIER combat electrical erosion in a wide range of conditions, including high humidity. Sealed protective coatings on the outer or inner rings integrate insulating properties into the bearing. They eliminate premature bearing failures caused by stray electric current in applications including:

• Industrial electric motors
• Traction motors
• Generators

High Precision Insulated Bearing 6320/C3VL0241 is Deep Groove Ball Bearing design. its dimension is 100×215×47mm, it has the same dimension and the same design with normal chrome steel 6318/C3 bearing. but the most different is 6320-C3J20AA bearing with Aluminium Oxide Coating. this insulated can be inner ring coating or outer ring coated. the coating can Electrical Resistance Voltages up to 3000 V DC. This kind of bearing are widely used in high quality demand application like traction motor.


Electrically Insulated Bearing are not only Electrically Insulated deep groove ball Bearing, but also Electrically Insulated Cylindrical Roller Bearing, Electrically Insulated Tapered Roller Bearing, Electrically Thrust Roller Bearing and the other type Normal or Non-Standard Electrically Insulated Rolling Bearings. they are the same dimension, same cage, same elements and the other data with normal chrome steel rolling bearing, just the different coating on the surface of the inner ring or outer ring of the Rolling Bearing.


Coated outer ring

Bearings with an electrically insulating coating on the external surfaces of the outer ring are the most common insulated bearing types. They are:

• Recommended for medium-sized motors using bearing sizes with a bore diameter < 120 mm

• Suitable for all housing types

• Can be applied to bearings with an outside diameter > 80 mm

• Identiied by the sufixes VL0241 and VL0246

Coated inner ring

Bearings with an electrically insulating coating on the external surfaces of the inner ring provide enhanced protection against electric current damage, as the smaller coated surface area offers higher impedance. They are:

• Recommended for larger-sized motors using bearing sizes with a bore diameter > 120 mm

• Can be applied to bearings with a bore diameter > 70 mm

• Identiied by the sufix VL2071 and VL2076



Current-Insulated  Bearings Prevent Damage Caused by Electrical Current

Features and Benefits of Coated Bearings 6320/C3VL0241


Coating of electrically insulated bearing


Electrically Insulated bearings have outer ring coating, inner ring coating and ceramic material rolling elements. Because of the higher cost of using ceramic material rolling elements, in most cases, the inner ring or outer ring 50-200 μm is used. Thick ceramic coating. The first two coatings are plasma spraying method to coat ceramic material on the bearing surface. This coating still maintains its insulation performance in a humid environment. The ceramic material rolling element insulated bearing is the rolling element. Using ceramic materials, it has excellent current resistance capability.

 

These three methods can make the deep groove ball bearing achieve the effect of insulation, so that the bearing will not be damaged by current during operation, and it can resist the electric flashover generated under 1000V voltage. The thicker coating can resist the high voltage above 1000V. Discharge.
