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 23164RK bearing.
The KOYO 23164RK is a Spherical Roller Bearing with a tapered bore designed for mounting using an adapter sleeve. The "RK" suffix indicates a specific internal design and the inclusion of mounting hardware. 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 "RHAK" variant is the internal design and cage material, making the "RK" a robust, standard-duty option.
The core dimensions (bore, OD, width) are identical to other 23164 bearings. The differences are internal and related to mounting.
Parameter | Value | Description |
---|---|---|
Bearing Type | Spherical Roller Bearing with Tapered Bore & Adapter Sleeve | |
Shaft Diameter (d) | 320 mm | This is the nominal bore size. The actual shaft size will be smaller. |
Outside Diameter (D) | 540 mm | The outer diameter of the bearing. |
Width (B) | 176 mm | The total width of the bearing. |
Dynamic Load Rating (C) | ~2,700 kN | The load capacity. Typically slightly lower than the RHA design. |
Static Load Rating (C₀) | ~5,100 kN | The maximum stationary load. Typically slightly lower than the RHA design. |
Grease Limit Speed | ~630 rpm | Maximum speed with grease lubrication. |
Oil Limit Speed | ~800 rpm | Maximum speed with oil lubrication. |
Adapter Sleeve | H 2364 | The designated adapter sleeve required for mounting. |
Shaft Size Range (with sleeve) | ~300 - 310 mm | The actual diameter of the straight shaft to be machined (must be confirmed via H 2364 sleeve tables). |
Weight | ~160 kg | Approximate total weight (bearing + sleeve + nut + washer). |
Note: Load and speed ratings are approximate. Always consult the specific product catalog for exact values.
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 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 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: 23164RK = A robust, standard-duty spherical roller bearing with a tapered bore and adapter sleeve, likely featuring a pressed steel cage and symmetric rollers.
Features:
Tapered Bore & Sleeve Mounting: Allows for easy installation and removal on straight shafts and enables precise adjustment of the internal clearance.
Self-Alignment: Compensates for misalignment caused by shaft deflection or mounting errors.
High Load Capacity: Excellent for heavy radial loads, though marginally less than the modern RHA design.
Cost-Effectiveness: Often a more economical choice than the premium RHAK version for applications where the highest load capacity and extreme robustness are not absolutely critical.
Typical Applications:
This bearing is found in a wide range of heavy-duty equipment, including:
Industrial Gearboxes
Conveyor Drive Pulleys
Large Fans and Blowers
Pumps
Crushers
Paper Mill Machinery
Feature | 23164RK | 23164RHAK |
---|---|---|
Internal Design | Likely Symmetric Rollers | Asymmetric Rollers (A) |
Cage Material | Pressed Steel / Brass | Hardened Steel (H) |
Load Capacity | Standard / High | Higher / Premium |
Robustness | Good for most applications | Superior for shock/vibration |
Typical Use Case | General heavy-duty industry | Extreme-duty, critical applications |
Like other "K" versions, mounting the 23164RK requires:
A correctly machined straight shaft to the dimensions specified for the H 2364 adapter sleeve.
Proper tightening of the locking nut to achieve the correct interference fit and internal clearance.
