The NTN Bearing Part Designation System Nomenclature consists of a combination of letters and numbers that identify different aspects of the bearing’s characteristics. The structure generally consists of six digits, but can vary depending on the type of bearing. The structure is as follows:
The basic number and prefix of the part number of an NTN bearing provide valuable information about the bearing’s series and type. The first two digits of the basic number typically identify the series or type of the bearing. For example, a bearing with a basic number of “63” is part of the 6300 series, while a basic number of “12” indicates the bearing is part of the 1200 series.
The prefix “NTN” identifies the manufacturer and ensures that the bearing is a genuine NTN product. However, it is important to note that not all NTN bearings have the prefix “NTN.” In some cases, the prefix may be omitted, especially for older bearings.
The suffix of the NTN Bearing Part Designation can vary depending on the bearing’s configuration and special features. The following letters are commonly used as suffixes:
Other letters may be used to indicate specific features of the bearing, such as seals, shields, or special materials used in construction.
