Insulated bearing with a layer of PPS insulating resin material coating on the width and the outer ring has the characteristics such as anti-corrosion, high reliability, cost-effective and can mainly be applied to PWM controlled motor.
Under some special conditions, the potential difference between the inner and outer ring will be accumulated, when the potential difference is larger than the critical value, the inner and outer ring will be forced to pass the electric current instantly, and the sparks will be generated in the bearing due to the electric current, and erosion will occur on inner and outer ring raceway.
Recently, in response to the demand for energy saving and efficiency, the demand for inverter motors has increased rapidly. Electrical erosion caused by external current and voltage sources such as inverters and encoders has increased accordingly.
Price of TPI insulated bearing has the best advantage against ceramic ball bearings widely used in the industry currently, and the insulation test was proved to reach the level of ceramic ball bearings. TPI insulated bearings could be your reliable partner in the next generation.
