Structure of NTN Bearing Part Designation System Nomenclature

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:

  • Prefix – Identifies the manufacturer of the bearing. For NTN bearings, the prefix is “NTN.”
  • Basic Number – The basic number identifies the series or type of bearing. This part of the part number consists of two or more digits, depending on the bearing type.
  • Suffix – The suffix is a letter or letters that indicate the bearing’s configuration or special features.
  • Internal Design – Depending on the type of bearing, additional codes may be used to
    further define the internal design or other features of the bearing.
  • Material – A letter or letters may be used to designate the material from which the bearing is made.
  • Cage Type – A letter or letters may be used to indicate the bearing’s cage type.

Understanding the Basic Number and Prefix of the NTN Bearing Part Designation

  • 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.

Understanding the Suffix of the NTN Bearing Part Designation

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:

  • C – Indicates that the bearing has a steel cage.
  • D – Indicates that the bearing has a snap ring groove in the outer ring.
  • J – Indicates that the bearing has hardened high carbon chromium steel rollers.
  • G – Indicates that the bearing has a tapered bore.
  • L – Indicates that the bearing has a removable inner ring.

Other letters may be used to indicate specific features of the bearing, such as seals, shields, or special materials used in construction.

Conclusion:

  • In conclusion, NTN Bearing Part Designation System Nomenclature is a concise and consistent way to describe the characteristics of NTN bearings.
  • By understanding the different parts of the part number, customers can identify the right bearing for their specific application. The prefix and basic number provide information about the bearing’s series and type, while the suffix indicates the bearing’s configuration and special features.
  • When researching bearings, it is crucial to have a good understanding of the NTN Bearing Part Designation System Nomenclature to ensure that the bearing meets the needs of the application.
