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 23156RHA bearing.
The 23156RHA is a Spherical Roller Bearing from KOYO, a major Japanese bearing manufacturer (now part of JTEKT Corporation). It's designed to handle very heavy radial loads and moderate axial (thrust) loads in both directions. The "RHA" suffix indicates specific internal design and cage material features.
This bearing is a staple in heavy industrial machinery where shock loads and misalignment are common.
Here is a table of the key dimensions and specifications for the 23156RHA bearing:
Parameter | Value | Description |
---|---|---|
Bearing Type | Spherical Roller Bearing | |
ISO Dimension Series | 31 Series (Heavy) | |
Shaft Diameter (d) | 280 mm | Bore size, the inner diameter that fits onto the shaft. |
Outside Diameter (D) | 460 mm | The outer diameter of the bearing. |
Width (B) | 146 mm | The total width or thickness of the bearing. |
Dynamic Load Rating (C) | ~2,100 kN | The load the bearing can endure for 1 million revolutions. Indicates capacity for rotating applications. |
Static Load Rating (C₀) | ~3,800 kN | The maximum stationary load the bearing can handle without permanent deformation. |
Grease Limit Speed | ~850 rpm | Maximum rotational speed recommended for grease lubrication. |
Oil Limit Speed | ~1,100 rpm | Maximum rotational speed recommended for oil lubrication. |
Weight | ~95 kg | Approximate weight of the bearing. |
Note: Exact values for load ratings and limiting speeds can vary slightly depending on the specific internal design and the reference catalog used. Always consult the latest official KOYO/JTEKT catalog for critical design calculations.
KOYO uses suffix codes to denote specific design features. For 23156RHA:
R: Enhanced Internal Design. This typically refers to an optimized internal geometry (roller design, raceway profile) that improves load capacity, reduces friction, and/or lowers operating temperature compared to a standard design.
H: Hardened Cage. The cage (which separates and guides the rollers) is made from hardened steel. This is crucial for applications with high vibration, shock loads, or high speeds where a pressed steel or brass cage might fail.
A: Internal Design Asymmetry. This indicates that the rollers and raceways have an asymmetric design. An asymmetric design generally provides higher load capacity and better performance under extreme misalignment and heavy loads compared to older symmetric designs.
In simple terms: RHA = A heavy-duty, high-performance, robust version of a standard spherical roller bearing.
