Of course. Here is a detailed parameter introduction for the KOYO 23160R bearing.

Quick Summary

The KOYO 23160R is a large-bore Spherical Roller Bearing designed for extremely heavy radial loads and moderate axial loads. The "R" suffix indicates it features an enhanced internal design for superior performance. It is a cornerstone component in the most demanding heavy industrial applications.


Detailed Parameter Breakdown

This is a very large bearing, part of the 23160 size series. Here are its key dimensions and specifications:

ParameterValueDescription
Bearing Type
Spherical Roller Bearing
Shaft Diameter (d)300 mmThe bore size that fits onto the shaft.
Outside Diameter (D)500 mmThe outer diameter of the bearing.
Width (B)160 mmThe total width or thickness of the bearing.
Dynamic Load Rating (C)~2,400 kNThe radial load the bearing can endure for 1 million revolutions. Extremely high.
Static Load Rating (C₀)~4,500 kNThe maximum stationary load without permanent deformation.
Grease Limit Speed~750 rpmMaximum rotational speed recommended for grease lubrication.
Oil Limit Speed~950 rpmMaximum rotational speed recommended for oil lubrication.
Weight~120 kgApproximate weight of the bearing. A heavy-duty component requiring professional handling.

Note: Exact values for load ratings and limiting speeds can vary. Always consult the latest official KOYO/JTEKT catalog for critical design calculations.


Suffix Code Explanation (R)

The suffix is critical for understanding this bearing's capabilities:

  • R: Enhanced Internal Design. This is the key feature. It signifies that KOYO has optimized the internal geometry of the bearing. This typically includes:

    • An asymmetric roller profile for better load distribution and reduced friction.

    • An optimized raceway and flange design.

    • The result is higher load capacity, lower operating temperatures, and longer service life compared to a standard spherical roller bearing of the same size without the "R" suffix.

  • No "K": The absence of a "K" suffix indicates this bearing has a straight cylindrical bore. It is designed to be mounted directly onto a shaft that has been machined to a precise tolerance (typically a tight interference fit).

  • No "H": The absence of an "H" suffix suggests it likely features a standard cage, which could be made of pressed steel or machined brass, rather than a hardened steel cage. For confirmation, checking the KOYO catalog for this specific suffix combination is essential.


Key Features and Benefits

  1. Exceptional Load Capacity: Its primary purpose is to handle extremely heavy radial loads and moderate axial loads in both directions.

  2. Self-Alignment: The spherical outer ring raceway allows it to compensate for static misalignment (typically up to 1.5-2.5 degrees) caused by shaft deflection or mounting errors.

  3. High Performance Design (R suffix): The enhanced internal geometry reduces internal stress and friction, leading to higher reliability and efficiency under extreme loads.

  4. Robust Construction: Built to withstand the harsh conditions of heavy industry, including shock loads and vibration.


Typical Applications

This bearing is found in the heart of massive machinery:

  • Gearboxes for mining excavators, draglines, and ball mills

  • Vibrating Screens and crushers in mining and aggregate processing

  • Marine Propulsion Systems and stern tubes

  • Large Pumps and fans

  • Paper Mill Machinery (e.g., dryer rolls)

  • Metal Rolling Mills

Installation Notes

  • Shaft Preparation: Due to the straight bore and immense size, the shaft must be machined to a very precise tolerance (usually a tight interference fit, like m5 or n5).

  • Mounting: Installation requires professional tools and techniques. Heating the bearing is mandatory for installation. This is almost always done using a controlled induction heater to expand the inner ring uniformly. Never use an open flame.

  • Lubrication: Proper lubrication is critical. A high-quality, high-viscosity grease with extreme pressure (EP) additives is typically required. For high-speed applications, an oil circulation system might be necessary.

  • Alignment: While self-aligning, best practice is to ensure the best possible initial alignment to maximize bearing life.
