Description

200rr-koyo
Japan’s koyo  bearing
 company produces tens of thousands of high-precision and high-quality Koyo bearing series products), providing information about aerospace technology, computer components, motors, high-speed trains, MRT trains, industrial machinery, CNC lathes, high-precision machining machines, automobile, locomotive industry, steel industry And other important components to make the best choice.

Of course. The code KOYO 23192RHA refers to a specific variant of a very large, heavy-duty tapered roller bearing.

Here is the detailed breakdown:

KOYO Bearing 23192RHA

  • Manufacturer: KOYO (JTEKT Corporation).

  • Type: Tapered Roller Bearing. Designed to handle extremely heavy combined radial and axial loads.

  • Series: The prefix 23192 defines the bore size and external dimensions.

    • The "2" signifies a metric tapered roller bearing.

    • The "3" indicates a wide contact angle, optimized for heavy axial loads.

    • The number "192" specifies the bore size.

  • Bore Diameter: The bore size (inner diameter) for this bearing is 460 mm. This is calculated from the last two digits of the basic number ("92") using a standard formula for large bore bearings.

  • Suffix: The suffix RHA is crucial and defines specific, high-performance features:

    • R: Indicates a flanged outer ring (cup). The flange acts as a shoulder, making axial location and installation into the housing simpler and more secure.

    • HA: Signifies that the rollers and cone (inner ring) are made from case-hardened steel. This process creates a very hard, wear-resistant outer surface while maintaining a tougher, more shock-resistant core. This is essential for bearings handling extreme loads, shock loads, and contamination in the most demanding applications.


Key Specifications (Approximate Dimensions)

The external dimensions are identical to the standard 23192R version.

DimensionValue (mm)Value (inches)
Bore Diameter (d)460 mm18.1102 in
Outer Diameter (D)780 mm30.7087 in
Width (T)~ 256 mm~ 10.0787 in
Weight~ 298 kg~ 657 lbs

Important Note: Always refer to the official KOYO/JTEKT engineering catalog for precise dimensions, exact load ratings (Dynamic & Static), and tolerances before design and installation.


The Significance of the "HA" Suffix

This is the key differentiator from a standard 23192R bearing. The HA designation means the bearing's internal components (the cone and rollers) are case hardened.

  • Standard 23192R: Internal components are made from standard through-hardened steel.

  • 23192RHA: Internal components are case-hardened. This provides:

    • Superior Fracture Resistance: The tough core prevents cracking under extreme shock and impact loads.

    • Enhanced Wear Resistance: The hard outer surface resists abrasion and extends bearing life, especially in contaminated environments.

    • Improved Fatigue Life: Better ability to withstand the stress of heavy, cyclic loading.

Common Applications

This bearing is used in the most severe applications where its advanced features are necessary:

  • Mining Equipment: Gyratory crushers, rotary blast hole drills, and the propel drives of massive draglines.

  • Heavy Construction Machinery: The main drives and propel systems of the largest excavators and mining shovels.

  • Metal Rolling Mills: Work roll backups in roughing stands where loads and shock are highest.

How to Find More Information or a Replacement

  1. Cross-Reference: This bearing can be cross-referenced with other brands that use the same suffix system, such as Timken 23192RHA.

  2. Search Online: Use the full part number "23192RHA" in your search on industrial supplier websites.

  3. Consult a Catalog: For critical technical data, always look up the part number in the official KOYO Tapered Roller Bearing catalog.

In summary, the KOYO 23192RHA is a giant, severe-duty, metric tapered roller bearing with a flanged outer ring and case-hardened internal components. It represents the top tier of performance and durability for the most extreme industrial applications.
