Of course. The code KOYO 23188R refers to a specific tapered roller bearing from the KOYO (JTEKT) series.

Here is the detailed information for that bearing:

KOYO Bearing 23188R

  • Manufacturer: KOYO (A major Japanese bearing manufacturer, now part of JTEKT Corporation).

  • Type: Tapered Roller Bearing. This type is designed to handle heavy combined radial and axial loads simultaneously.

  • Series: The prefix 23188 indicates the series, which defines the bore size and the external dimensions.

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

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

    • The number "188" specifically defines the bore size and the overall dimensions of the cup (outer ring) and cone (inner ring assembly).

  • Bore Diameter: The bore size (the inner diameter where it fits on the shaft) for this bearing is 440 mm. This is calculated from the last two digits of the basic number ("88") using a standard formula for large bore bearings.

  • Suffix: The suffix R is a common designation that typically indicates the bearing has a flanged outer ring (cup). The flange acts as a shoulder, making axial location and installation into the housing simpler and more secure.


Key Specifications (Approximate Dimensions)

Here are the standard dimensions for a 23188R bearing:

DimensionValue (mm)Value (inches)
Bore Diameter (d)440 mm17.3228 in
Outer Diameter (D)720 mm28.3465 in
Width (T)~ 226 mm~ 8.8976 in
Weight~ 206 kg~ 454 lbs

Important Note: Always refer to the official KOYO/JTEKT engineering catalog for the most precise dimensions, load ratings (Dynamic & Static), and exact tolerances before design and installation. The "R" suffix can sometimes have minor variations in meaning between manufacturers, so confirming with the technical sheet is crucial.
