Insulated Bearings 6222 M/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 6222 M/C3VL0241  is Deep Groove Ball Bearing design. its dimension is 110×200×38mm, it has the same dimension and the same design with normal chrome steel 6222 M/C3 bearing. but the most different is 6222-M-C3J20AA bearing with Aluminium Oxide Coating. 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 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.

Features and Benefits of Coated Bearings 6222 M/C3VL0241


Coating of electrically insulated bearing

Coated outer ring

Bearings with an electrically insulating coating on the external surfaces of the outer ring are the most common INSOCOAT 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


And different types of Electrically insulated bearings also have their different design according to their feather, and also many kinds of cages, just like Brass cage, Pressed Steel cage, nylon cage etc.

 

So Electrically insulated bearings also have above mentioned characteristic with normal Non insulated bearings.The bearings can meet the challenges of applications faced with heavy radial loads and high speeds. Accommodating axial displacement (except for bearings with flanges on both the inner and outer rings), they offer high stiffness, low friction and long service life.
