NSK Deep Groove Ball Bearings, Basic Designation
NSK deep groove ball bearings in this group carry a basic designation made up of digits only, for instance 602, 6204, 6908 or 60/630. The range spans many series and sizes, from miniature bearings up to large-diameter units. The shared element is the design itself; each part number brings its own dimensions, so the complete number has to be quoted.
