Product Features
The process has been continuously improved, insulated bearings, in
the outer ring or inner ring surface with a layer of 100μm thick
coating, can withstand up to 1000 V DC voltage. Special spraying
process can form a layer of uniform thickness, strong adhesion
uniform coating, and then after further treatment, so that it can
not be affected by moisture and humidity.

Cage
According to different bearing series and size, electrical
insulation bearing with the following cage:
Reinforced nylon 66 cage
Stamping steel plate holder
Car body solid copper cage
Advantage
Electrical insulation bearings can avoid damage caused by
electrical corrosion, so compared with ordinary bearings in the
motor can be used to ensure more reliable operation. Compared to
other insulation methods, such as shaft or shell insulation, more
cost-effective and reliable. Insulated bearing dimensions and basic
technical characteristics and non-insulated bearings the same, it
can be 100% swap.
Application
Applicable to motors, generators, especially variable frequency
motors are more widely used.

Current-insulated bearings have the same dimensions and load
carrying capacities as those without insulation, which makes them
perfectly interchangeable.
The most common type of insulation used in electric motor
applications is the J20AA coating. It offers excellent protection
against passage of electrical current, even in damp atmospheres.
Bearings with ceramic coating are available with seals also.
Bearings with J20C coating on the inner ring are used in special applications as well as applications where the outer ring rotates. Z shields can be used as well.
Ordering examples:
Hybrid bearings (HC): Hybrid bearings are characterized by the fact that the rolling elements are made of ceramic. They offer maximum protection against passage of electrical current. At the same time, hybrid bearings are suitable for higher speeds and have better dry-running characteristics.
