Bearing data - general
Unless tailored to meet the demands of a specific application, the dimensions, tolerances and internal clearance (where applicable) of SKF bearings conform to International Standards so that interchangeability is assured. Detailed information on which Standards apply will be found in the introductory text to each section dealing with a specific bearing type.
The materials used for SKF bearings are of the best quality and chosen for the dominant application areas for the particular bearing type.
The designation system used for SKF bearings has been devised to provide as much information as possible about the bearing. It has not been ISO practice to standardize designations although the basic designations describing bearing type and size are used by many manufacturers.
