  • 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.
  • Bearings in this group have various types of high speed cages.
  • Speed ratings range from 20 percent to 80 percent increase on standard cage types.
  • See individual datasheets, available on request.
