Brief: See the solution in real use and note how it behaves under normal conditions. This video demonstrates the 6004 and 6005 full zirconia ceramic bearings with ZrO2 rings and balls, showcasing their performance in extreme corrosion, high-speed, and dry-running applications. Watch as we explain how the PTFE cage and seals create a maintenance-free, electrically insulating bearing ideal for harsh environments.
Related Product Features:
  • Full zirconia ceramic construction with ZrO2 rings and balls for exceptional corrosion resistance against strong acids, alkalis, and solvents.
  • PTFE cage provides superior self-lubrication with the lowest coefficient of friction, enabling dry or boundary lubrication operation.
  • Electrical insulator prevents electrical pitting from VFD drives, making it ideal for variable frequency drive motors.
  • Non-magnetic properties ensure compatibility with precision instruments and medical devices without interference.
  • 45% lighter than steel with high hardness and toughness, offering excellent wear and impact resistance.
  • Operates in extreme temperatures from -200°C to +250°C, reliable in high-temperature and vacuum environments.
  • Available in P6 and P5 precision grades, manufactured to international standard 6201 dimensions for consistent performance.
  • Maintenance-free operation with self-lubricating PTFE cage, reducing friction and wear significantly compared to metal-caged bearings.
FAQs:
  • What are the key advantages of using full zirconia ceramic bearings over traditional steel bearings?
    Full zirconia ceramic bearings offer exceptional corrosion resistance against strong acids and alkalis, electrical insulation to prevent pitting from VFD drives, non-magnetic properties, and are 45% lighter than steel with high wear resistance, solving common failures of steel bearings in harsh conditions.
  • In which applications are these 6004 and 6005 ceramic bearings most suitable?
    These bearings are ideal for chemical and plating equipment, food and pharmaceutical machinery, variable frequency drive motors, semiconductor manufacturing, precision instruments, medical devices, and high-temperature or vacuum environments due to their corrosion resistance, non-magnetic nature, and lubricant-free operation.
  • How does the PTFE cage contribute to the bearing's performance?
    The PTFE cage provides superior self-lubrication with the lowest coefficient of friction, excellent chemical resistance matching zirconia, and a non-stick surface capable of operating from -200°C to +250°C, resulting in very low friction and wear in dry or boundary lubrication states.
  • What precision grades and dimensions are available for these ceramic bearings?
    The 6004 and 6005 full zirconia ceramic bearings are manufactured to international standard 6201 dimensions and are available in P6 and P5 precision grades, ensuring high performance and consistency for demanding applications.
