description

  • Current insulated ball bearings feature Schaeffler’s proprietary Insutect™ ceramic coating that provides insulation to current passage of up to 3,000 VDC. Electrical current passing through bearings in electric motors can cause raceway damage that leads to premature bearing failure and, ultimately, expensive machine downtime.

applications

  • Electric motors
  • Traction motors (ex: railway applications)
  • Generators (ex: wind turbines)

features

  • Insutect™ ceramic coating available on outer ring (J20AA) or inner ring (J20C)
  • J20C version well suited for high frequency currents with a rotating outer ring
  • Hybrid Ceramic (HC-prefix) bearings offer significantly higher electrical resistance (GΩ range)
  • Can be combined with lip seals and dust shields
  • Brass and steel cage options
  • High electrical resistance
  • Interchangeable with standard ball bearings
  • Long bearing operating life/longer maintenance intervals
  • Extended grease life
  • Generates less heat
  • Offers maximum protection from electric arcing damage
