BEARING DESIGNATION SYSTEMS
Within each order code, a distinction is made between the basic designation and any suffixes and/or prefixes. The basic designation indicates the bearing type and the bore size. These basic designations are defined in the. German DIN 623 standard and the relevant. ISO standard. For most bearing types, the. Maintains ISO standards and other operating criteria. □ Service life doubled when compared to SKF standard shield greased bearings. □ Reduced running temperature. □ Extended range. □ Available in sealed and shielded versions.
