  • RD Type (Light Contact) Sealed Ball Bearings

    Koyo's efforts in R&D resulted in our newly devel- oped RD type sealed ball bearings to satisify these demands. With torque as low as that of non-contact sealed ball bearings, yet a seal nearly as tight as contact type product, superior protection from water and dust has been achieved.
