Prevention methods of bearing current damage

Use insulated bearings. Electrically insulated bearings can fundamentally eliminate galvanic corrosion by integrating insulation properties into the bearings, thereby improving reliability and increasing machine uptime. Electrically insulated bearings usually have an outer ring outer diameter surface and an end surface coated with alumina. Insulated bearings with coated inner ring bores and end faces, because the inner ring has a smaller coated surface area than the outer ring, these bearings can provide enhanced protection against high-frequency currents. Insulated bearings use a special spraying process to spray high-quality coating on the outer surface of the bearing. The coating has a strong bonding force with the matrix and good insulation performance. The damage caused by the raceway increases the service life of the bearing. It is suitable for motors and generators, especially variable frequency motors.

Since founded in 2011, Eric bearing Limited has established cooperative partnership with some distributors authorized the world renowned manufacturers likeSweden SKF Bearing, Germany FAG and INA Bearing, Japan NSK Bearing, Japan NTN Bearing, Japan IKO Bearing,Japan KOYO Bearing,Japan NACHI Bearing and America TIMEKN Bearing ,etc . Compared with other competitor , our price is very competitive , 30% lower than customer local market , We set up several branch warehouse in HongKong Free Port. ShangHai Port and GuangZhou Port.
