Insulated Bearing

The process has been continuously improved, and in insulated bearings, there is a coating 100μm thick on the surface of the outer or inner ring, which can withstand voltages up to 1000 V DC. A special spraying process creates a coating with uniform thickness and extremely uniform adhesion, which is then further treated so that it is not affected by moisture and humidity.

Electrically insulated bearings can avoid damage caused by electrical corrosion, so it can ensure more reliable operation in motors than ordinary bearings. It is more cost-effective and reliable than other insulation methods, such as shaft or shell insulation. The dimensions and basic technical characteristics of insulated bearings are the same as those of non-insulated bearings, so they can be 100 percent interchangeable.

Insulated bearings have a wide range of applications in various industry equipment, including but not limited to the following areas:

1. Power industry: In the power industry, insulated bearings are widely used in wind turbines, hydrogenerators and thermal generators and other facilities. This is because the insulated bearing can avoid the electric corrosion of the induced current on the bearing, prevent the effect of the current on the grease and the rolling element, and thus improve the service life of the bearing.

2. Railway facilities: In railway facilities, insulated bearings are also used in diesel locomotive traction motors and other equipment to avoid damage to bearings by current.

3. Other industrial applications: In mining machines, coal pickers, coal washing machines, crushers, ball mills, grinding machines, sand mills and other equipment, insulated bearings also play an important role. These equipment usually need to withstand high power and high voltage, and the insulated bearing can effectively prevent the damage of the current to the bearing and ensure the normal operation of the equipment.

In general, insulated bearings have been widely used in many industries and fields because of their special structure and excellent performance. In the future, with the continuous progress of technology and the continuous expansion of applications, the application prospects of insulated bearings will be broader.
