Bearings - Single Row Ball - Unflanged - High Precision - Standard

Standard High Precision Unflanged Single Row Ball Bearings. Stainless Steel Bearings - Abec 5 and Abec 7.

  • 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.
  • Single row radial ball bearings.
  • High precision bearings are not recommended for skates or fishing reels.
  • High precision bearings are used in accurately balanced application such as spindles, gyros and medical equipment.
  • If your application is not of a precision nature, standard bearings may be more suitable (and less expensive).
