Machined Brass Cage (M) — High mechanical strength, ideal for severe vibration and dynamic loads.
150mm Large Bore Construction — Engineered for massive industrial drive shafts.
High Dielectric Resistance — 50–200 MΩ, ensuring zero leakage of VFD shaft currents.
The TFL 6230M/C3VL0241 high-voltage insulated bearing is specifically supplied for heavy industries with highly demanding requirements for vibration and mechanical loads. Typical applications include rail traction motors, megawatt-class wind turbine generators, paper-making dryer drum drives, and variable-speed centrifugal pump systems.
TFL 6230M/C3VL0241 electrically insulated deep groove ball bearings can be applied in Alstom or Siemens rail traction motor systems. Operating under frequent track vibrations and high-frequency pulse currents, this model utilizes its high-strength machined brass cage and 3000V dielectric protection to safeguard raceways from both mechanical damage and electrical erosion.
In the wind power sector, TFL 6230M/C3VL0241 is suitable for the main generators of 2.5MW to 5MW wind turbines from brands like Vestas or Goldwind. The fatigue-resistant machined brass cage withstands intense load fluctuations during variable-speed wind operations, while the ceramic coating blocks leak currents and shaft voltages, extending the overall operating life.
For heavy-duty centrifugal feedwater pumps from brands like Sulzer or KSB, TFL 6230M/C3VL0241 provides excellent shaft-end isolation. Under VFD operation, where the equipment must handle constant fluid pulsations and electromagnetic impulses, the machined brass cage combined with the high-voltage insulation layer ensures stable pump operation in humid and heavy-load environments.
