8×220281

The designation 8×220281 refers to a specific type of roller bearing. The '8' indicates the bore diameter of the inner ring, which is 8 millimeters. The '220281' is a numerical code used by bearing manufacturers to identify the specific configuration and dimensions of the bearing. This code typically denotes a deep groove ball bearing with a bore diameter of 8mm, an outer diameter of 22mm, and a width of 7mm. These bearings are commonly used in applications requiring the support of radial loads and some axial loads in either direction. Their compact size and ability to handle moderate speeds make them suitable for a variety of uses, including electric motors, pumps, and small machinery. The designation is part of an international standard system for classifying bearings, ensuring interchangeability and consistent specifications across different manufacturers. Specific load ratings, lubrication requirements, and material compositions would be detailed in the manufacturer's technical data sheets for this particular bearing type.
