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 23160RHA bearing.
The KOYO 23160RHA is a premium, high-performance Spherical Roller Bearing with a straight cylindrical bore. It is engineered for the most demanding applications involving extreme radial loads, misalignment, and harsh operating conditions. The "RHA" suffix combination signifies a bearing with enhanced internal geometry and a robust hardened steel cage.
This is a large, heavy-duty bearing. Its core dimensions are part of the standardized 23160 size series.
Parameter | Value | Description |
---|---|---|
Bearing Type | Spherical Roller Bearing | |
Shaft Diameter (d) | 300 mm | The bore size that fits onto the shaft. |
Outside Diameter (D) | 500 mm | The outer diameter of the bearing. |
Width (B) | 160 mm | The total width or thickness of the bearing. |
Dynamic Load Rating (C) | ~2,500 kN | The radial load the bearing can endure for 1 million revolutions. Very high. |
Static Load Rating (C₀) | ~4,700 kN | The maximum stationary load without permanent deformation. |
Grease Limit Speed | ~750 rpm | Maximum rotational speed recommended for grease lubrication. |
Oil Limit Speed | ~950 rpm | Maximum rotational speed recommended for oil lubrication. |
Weight | ~120 kg | Approximate weight of the bearing. Requires 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.
The suffix combination is what defines this as a premium bearing. Each letter has a specific meaning:
R: Enhanced Internal Design. This indicates an optimized internal geometry. 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.
H: Hardened Steel Cage. This is a critical feature. The cage (which separates and guides the rollers) is made from through-hardened steel. This provides:
Superior strength and resistance to shock loads.
High resistance to wear and deformation.
Exceptional performance in high-vibration applications where other cages might fail.
A: Internal Design Asymmetry. This suffix often reinforces the "R" designation, explicitly confirming the use of advanced asymmetric rollers for maximum performance.
In summary: 23160RHA = A top-tier spherical roller bearing with an optimized asymmetric design and an ultra-robust hardened steel cage.
Ultra-High Load Capacity: Designed to withstand the most severe radial loads and moderate axial loads.
Superior Robustness (H Cage): The hardened steel cage makes it ideal for applications with high vibration, impact loads, and potential cage-slippage issues.
Self-Alignment: Compensates for static misalignment (up to ~1.5-2.5°) from mounting errors or shaft deflection.
High Efficiency (R/A Design): The asymmetric roller design reduces friction, leading to lower operating temperatures and higher energy efficiency.
Long Service Life: The combination of enhanced geometry and a robust cage maximizes reliability and service life in critical machinery.
This bearing is specified for the most critical and heavy-duty applications across various industries:
Gearboxes in mining equipment (e.g., large excavators, draglines, ball mills)
Vibrating Screens and crushers in mining and aggregate processing
Marine Propulsion Systems and stern tubes
Large Pumps and fans in power generation
Metal Rolling Mills
Paper Mill Dryer Rolls
Heavy-duty industrial fans
Shaft Fit: This bearing has a straight cylindrical bore. The shaft must be machined to a very precise tolerance (usually a tight interference fit, like m5 or n5) to ensure a secure mount.
Mounting: Due to its size and weight (~120 kg), professional tools and procedures are essential. Heating the bearing using a controlled induction heater is mandatory for installation to expand the inner ring. Never use an open flame.
Lubrication: Proper lubrication is critical. Use a high-quality, high-viscosity grease with extreme pressure (EP) additives. 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.
