• Features & Benefits
  • Electric motors are the single largest user of energy in Industrial/Commercial facilities and can account for up to 70% of their total energy consumption—leading to the need for energy efficient solutions such as Koyo’s RD Light Contact Seal Ball Bearings • Koyo’s unique seal design reduces seal drag and energy consumption in electric motor applications while providing superior seal performance and grease retention • Provides a two-fold benefit to standard sealed bearings—innate design characteristics of the RD seal reduces drag, frictional torque and operating temperature • The closure provided is superior to standard seals, helping to inhibit the ingress of contaminants and moisture • Optimal design selection and mechanical advantages from the RD translate into longer life and increased efficiency in electric motor applications
