The NSK deep groove ball bearings of this type have a basic designation, made up only of numbers, such as 602, 6204, 6908 or 60/630. They cover very different series and sizes, from very small bearings to large-diameter ones. What they have in common is the design; the dimensions change with each part number, which is why it must be given in full.

A deep groove ball bearing has one row of balls between two rings with deep raceways. This geometry allows it to support radial loads and also moderate axial loads in both directions, with low friction. It is the most widespread design in electric motors, fans, pumps, conveyors and all kinds of general-purpose machinery.

In the designation, the numbers identify series and size: two similar part numbers can have very different diameters or widths. For example, 6204 and 6214 share the first two digits, but not the dimensions. Part numbers with a slash, such as 60/630 or 69/600, and five-digit ones, such as 16001, are also part of this type and are identified by their full number.

When replacing a bearing, take the part number engraved on the ring. If it is not legible, measure the bore diameter, the outside diameter and the width. These three dimensions, together with the part number, confirm that it is the same bearing. Part numbers of this type carry no suffixes: they correspond to the basic designation of each bearing.

During mounting, apply force on the ring with the tight fit and never through the balls, use tools that seat evenly and avoid direct blows. Check the condition of the shaft and the housing, and lubricate according to speed, temperature and load, following the manufacturer's instructions.
