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. Here is a detailed parameter introduction for the KOYO 23164R bearing.
The KOYO 23164R is a large-bore Spherical Roller Bearing with a straight cylindrical bore and an enhanced internal design. The "R" suffix indicates it features optimized internal geometry for superior performance under extremely heavy radial loads and moderate misalignment. It is a critical component in the most demanding heavy industrial machinery.
This is a very large bearing, part of the standardized 23164 size series. Here are its key dimensions and specifications:
Parameter | Value | Description |
---|---|---|
Bearing Type | Spherical Roller Bearing | |
Shaft Diameter (d) | 320 mm | The bore size that fits onto the shaft. |
Outside Diameter (D) | 540 mm | The outer diameter of the bearing. |
Width (B) | 176 mm | The total width or thickness of the bearing. |
Dynamic Load Rating (C) | ~2,800 kN | The radial load the bearing can endure for 1 million revolutions. Extremely high. |
Static Load Rating (C₀) | ~5,300 kN | The maximum stationary load without permanent deformation. |
Grease Limit Speed | ~670 rpm | Maximum rotational speed recommended for grease lubrication. |
Oil Limit Speed | ~850 rpm | Maximum rotational speed recommended for oil lubrication. |
Weight | ~155 kg | Approximate weight of the bearing. Requires professional handling and installation tools. |
Note: Exact values for load ratings and limiting speeds can vary. Always consult the latest official KOYO/JTEKT catalog for critical design calculations.
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, like m5 or n5).
No "H" or "A": The absence of an "H" (hardened steel cage) or "A" (explicit asymmetric design) suggests it likely features a standard cage (e.g., pressed steel or machined brass) and that the "R" suffix encompasses the general performance enhancement. For confirmation of the cage type, checking the KOYO catalog for this specific suffix is essential.
Exceptional Load Capacity: Its primary purpose is to handle extremely heavy radial loads and moderate axial loads in both directions.
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.
High Performance Design (R suffix): The enhanced internal geometry reduces internal stress and friction, leading to higher reliability and efficiency under extreme loads.
Robust Construction: Built to withstand the harsh conditions of heavy industry, including shock loads and vibration.
This massive bearing is found in the heart of the largest industrial machinery:
Gearboxes for mining excavators, draglines, and large ball mills
Vibrating Screens and crushers in mining and aggregate processing
Marine Propulsion Systems and stern tubes
Large Industrial Pumps and fans
Paper Mill Machinery (e.g., large dryer rolls)
Metal Rolling Mills
Kilns and other large rotating equipment
Shaft Preparation: Due to the straight bore and immense size and weight (~155 kg), 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.
