Bearings - Single Row Ball - Flanged - Precision - Extended Inner

Extended Inner Precision Flanged Single Row Ball Bearings. Single row radial ball bearings with flanges and extended inner rings (wide inner rings).

  • 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.
  • If the size you require is not available, you might consider using a standard bearing with shim washers.
