Bearings - Single Row Ball - Unflanged - Semi Ground

Semi Ground Unflanged Single Row Ball Bearings. Radial ball bearings. This series is precision ground on all contact surfaces except the bore. Recommended for lighter loads and maximum speed of 3000rpm. Bore tolerance is +0.127/-0.000, OD tolerance is +0.000/-0.013 and width is +0.000/-0.127

  • 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.
