Insulated Bearings
Rangyun focuses on R&D and manufacturing of insulated bearings. It uses plasma spraying to apply 100 - 200μm thick ceramic coatings on bearings, giving them good insulation against 1000V+ voltage. This prevents electric erosion and extends service life. Rangyun offers various types like deep groove ball bearings and cylindrical roller bearings for motors and frequency conversion equipment.
Rangyun Technology: Insulated Bearings
In insulated environments, our bearings have been widely used in the following fields/companies:
Power industry
Used in substations, power plants, and power station equipment to prevent current from flowing through the bearings and to protect the equipment.
Wind power generation
Rotating components in wind power generation often require insulated bearings to prevent the bearings from affecting the stability of the system.
Motor industry
Used in various motors and generators to prevent current leakage or electrical faults.
Railway industry
Used in electric locomotives in electrified railways to isolate the electrical system from the mechanical parts.
Electronic equipment
In high-precision electronic equipment, such as MRI or electrical testing instruments, insulated bearings are used to avoid current interference.
Communication industry
In communication equipment and antenna systems, some insulated bearings can prevent current interference and ensure stable operation of the equipment.
