Bearing number meaning
The bearing number typically consists of alphanumeric characters that convey specific information about the bearing’s type, size, series, and other relevant specifications. While the format can vary between manufacturers, here is a general explanation of the meaning behind bearing numbers:
1. Prefix: The prefix often consists of letters indicating the type or series of the bearing. Common prefixes include:
– “6” for deep groove ball bearings
– “R” for inch series bearings
– “T” for thrust bearings
– “NU” for cylindrical roller bearings
2. Suffixes: Suffixes are appended to the basic number to denote specific features, variants, or modifications of the bearing. These suffixes can indicate factors such as:
– Bearing clearance (e.g., C2, C3, C4)
– Bearing seals or shields (e.g., ZZ, 2RS)
– Bearing cage material (e.g., TN9 for glass fiber-reinforced polyamide)
– Special internal design or features (e.g., W for filling slot bearings)
3. Dimensional Details: Additional numbers or letters may indicate specific dimensional details such as bore diameter, outside diameter, width, or bore taper. These details help identify the physical dimensions of the bearing.
4. Basic Number: The basic number follows the prefix and represents the bearing’s size or series within a particular product line. It may not have a specific meaning across all manufacturers but serves as an identification number.
Interpreting bearing numbers accurately requires consulting the manufacturer’s specifications and documentation, as the format and meaning can vary between manufacturers and bearing standards. Understanding bearing numbers is essential for selecting the correct bearings for specific applications and ensuring proper installation and performance.
