Bearings - Single Row Ball - Unflanged - Precision - Ceramic ZrO2

Ceramic ZrO2 Precision Unflanged Single Row Ball Bearings. Excellent performance in electrical and magnetism sensitive applications. Not for High Speed. Full ceramic zirconia.

  • Single row radial ball bearings are arguably the most common, widely used type of bearing. They consist of an inner ring, an outer ring, a set of balls, and a cage that retains the balls in a circular path.
  • Single row radial ball bearings are commonly used in a wide range of applications, including electric motors, fans, pumps, gearboxes, agricultural equipment, appliances, and automotive components.
  • They are versatile, cost-effective bearings that provide reliable support for radial loads and some axial loads in one direction. An expanded range may be available on special order. Please enquire.
  • Applications include cryopumps, medical applications, semiconductors, turbine flow meters, food processing, robotics and optics.
  • Wear and corrosion resistance. Depending on the application, these bearings may run lubrication free or lubricated by the medium in which they are submerged.
  • Cages of PTFE or Glass Fibre Reinforced Nylon. Can be made from special aviation aluminum on request.
  • ZrO2 standard material for balls and rings. Si3N4 available to special order.
  • High and low- temperature application. Up to 250 Deg C with PTFE Cage and 130 Deg C with Nylon Cage. Up to 1000 deg C without a cage or seals.
