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 23156RK bearing.
The KOYO 23156RK is a Spherical Roller Bearing with a tapered bore designed for mounting using an adapter sleeve. The "RK" suffix is a key identifier of this mounting style. It is engineered to handle extremely heavy radial loads and moderate axial loads while compensating for shaft misalignment, making it a fundamental component in heavy industrial machinery.
The core difference from the previous examples is the "RK" suffix set, which indicates a specific, and slightly older, internal design and cage material compared to the "RHA" and "RHAK" variants.
The core dimensions (bore, OD, width) are identical to other 23156 bearings, as they are defined by the basic number. The differences are internal.
Parameter | Value | Description |
---|---|---|
Bearing Type | Spherical Roller Bearing with Tapered Bore | |
Shaft Diameter (d) | 280 mm | This is the nominal bore size. The actual shaft size will be smaller due to the adapter sleeve. |
Outside Diameter (D) | 460 mm | The outer diameter of the bearing. |
Width (B) | 146 mm | The total width of the bearing. |
Dynamic Load Rating (C) | ~1,900 kN | The load capacity for a lifetime of 1 million revolutions. Typically slightly lower than the RHA design. |
Static Load Rating (C₀) | ~3,500 kN | The maximum stationary load. Typically slightly lower than the RHA design. |
Grease Limit Speed | ~800 rpm | Maximum rotational speed recommended for grease lubrication. |
Oil Limit Speed | ~1,000 rpm | Maximum rotational speed recommended for oil lubrication. |
Adapter Sleeve | H 2356 | The designated adapter sleeve required for mounting on a straight shaft. |
Shaft Size Range (with sleeve) | ~260 - 270 mm | The actual diameter of the straight shaft to be machined (must be confirmed via H 2356 sleeve tables). |
Note: Load and speed ratings are approximate and based on a typical "RK" designation. Always consult the specific product catalog for the exact values, as they can vary between manufacturing periods.
This is the most important part for understanding this specific bearing. The suffixes have evolved over time.
R: Tapered Bore. This indicates the inner ring has a tapered bore (usually a 1:12 taper) for mounting with an adapter or withdrawal sleeve.
K: Adapter Sleeve Mounting. This signifies the bearing is supplied for use with an adapter sleeve. It often implies the bearing comes as a set, including the locking nut and locking washer.
Critical Interpretation of the Missing Suffixes:
The absence of an "H" or "A" in the suffix code is highly significant.
No 'H': This strongly suggests the cage is not a hardened steel cage. It is most likely a pressed steel cage or, in older designs, potentially a machined brass cage. This makes the bearing less suitable for extremely high-vibration or shock-load applications compared to an "H" type bearing.
No 'A': This indicates the bearing likely features an older, symmetric roller design. While still very robust, symmetric rollers generally have a lower load capacity and higher friction than the modern asymmetric ("A" suffix) design.
In summary: 23156RK = A robust, standard-duty spherical roller bearing with a tapered bore and adapter sleeve, likely featuring a pressed steel cage and symmetric rollers.
