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 23156RHAK bearing.
The KOYO 23156RHAK is a Spherical Roller Bearing with a tapered bore and an integral tapered adapter sleeve. It's designed for mounting on straight (non-stepped) shafts. This bearing is engineered to handle extremely heavy radial loads and moderate axial loads while compensating for misalignment, making it a critical component in heavy industrial machinery.
The key differentiator from a standard bearing is the "K" suffix, which signifies the inclusion of the adapter sleeve for mounting.
The core dimensions of the bearing itself (inner ring, rollers, etc.) are identical to the 23156RHA. The adapter sleeve adds additional mounting dimensions.
Parameter | Value | Description |
---|---|---|
Bearing Type | Spherical Roller Bearing with Tapered Bore & Adapter Sleeve | |
Shaft Diameter (d) | 280 mm | This is the nominal bore of the bearing itself. The actual shaft it fits 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 assembly. |
Adapter Sleeve Designation | H 2356 | The specific part number for the adapter sleeve. The "H" followed by the bearing bore size (280) is a standard coding system. |
Shaft Size Range (with sleeve) | ~260 - 270 mm | The actual diameter of the straight shaft you would machine for this bearing. This is the most critical mounting dimension. |
Dynamic Load Rating (C) | ~2,100 kN | The load the bearing can endure for 1 million revolutions. (Same as 23156RHA). |
Static Load Rating (C₀) | ~3,800 kN | The maximum stationary load. (Same as 23156RHA). |
Grease Limit Speed | ~850 rpm | Maximum speed with grease lubrication. The adapter sleeve slightly reduces this compared to a direct mount. |
Oil Limit Speed | ~1,100 rpm | Maximum speed with oil lubrication. |
Weight | ~105 kg | Approximate total weight (bearing + sleeve + nut + washer). |
Crucial Note: The exact shaft diameter must be determined from the KOYO adapter sleeve tables for H 2356. It must be machined to a very precise tolerance (e.g., h9 or h10) to ensure a tight, secure fit.
The suffix codes describe the bearing's features:
R: Enhanced Internal Design. Optimized geometry for higher load capacity and lower operating temperature.
H: Hardened Steel Cage. Provides superior strength and reliability under high vibration and shock loads.
A: Asymmetric Roller Design. Offers higher performance and reduced friction compared to older symmetric designs.
K: Tapered Bore and Adapter Sleeve. This is the key suffix. It indicates the bearing has a tapered inner ring bore and is supplied with an adapter sleeve (H 2356), locking nut, and locking washer for mounting on a straight shaft.
