Model analysis:

372260/HCC3

372260: indicates the model of the bearing, usually referring to the size and design of the bearing. The specific meaning of the number varies depending on the manufacturer’s naming rules, but generally identifies the inner and outer diameters and width of the bearing.
HCC3: This is the identification of the lubrication level and internal structure of the bearing. Usually, H represents special design or manufacturing requirements, while C3 represents larger internal clearance, suitable for use at higher temperatures or larger loads to cope with clearance changes caused by thermal expansion.
372268X3/C3

372268X3: Bearing model, indicating that this is a double row column roller bearing with specific dimensions and design.
X3: Usually identifies the design series or additional reinforcement design of the bearing, such as enhanced sealing, high temperature resistance, etc. X3 indicates that it has specific reinforcement or improved design to enhance performance.
C3: Refers to the internal clearance of the bearing. C3 clearance is larger than the standard clearance and is suitable for working conditions such as high temperature, high speed, or carrying large loads.
370672/HC

370672: The model of the bearing, indicating its size and basic design.
HC: usually represents the special material or high-temperature resistant design of the bearing, indicating that the bearing is suitable for use in high-temperature environments or has high wear resistance.
Product features:

Double row design:

Double row vertebral column roller bearings are composed of two rows of tapered rollers, designed to have higher radial and axial load-bearing capacity. The arrangement of two rows of rollers can share the load, thereby improving the bearing’s load-bearing capacity and stability.

High load-bearing capacity:

Double row vertebral column roller bearings can effectively withstand large radial loads and can also withstand certain axial loads, especially suitable for heavy machinery that requires strong load-bearing capacity.

Strong impact resistance:

This type of bearing design is suitable for applications with impact loads in the working environment, and can effectively reduce bearing damage caused by impact loads.

High temperature resistance performance:

By using C3 or HC markings, these bearings have a large internal clearance, which can cope with thermal expansion in high-temperature environments and ensure normal operation under large temperature fluctuations.
