SKF Bearing Designation Guide

The document outlines SKF's basic designation system for standard metric ball and roller bearings according to ISO 355. It provides a table that assigns a single-letter code to different bearing types, including double row angular contact ball bearings (code 0), self-aligning ball bearings (code 1), spherical roller thrust bearings (code 2), tapered roller bearings (code 3), and others. The system also uses additional letters to identify configurations for bearings like cylindrical roller bearings.
