Of course. Here is a detailed parameter introduction for the KOYO 23156RHAK bearing.

Quick Summary

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.


Detailed Parameter Breakdown

The core dimensions of the bearing itself (inner ring, rollers, etc.) are identical to the 23156RHA. The adapter sleeve adds additional mounting dimensions.

ParameterValueDescription
Bearing Type
Spherical Roller Bearing with Tapered Bore & Adapter Sleeve
Shaft Diameter (d)280 mmThis 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 mmThe outer diameter of the bearing.
Width (B)146 mmThe total width of the bearing assembly.
Adapter Sleeve DesignationH 2356The 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 mmThe 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 kNThe load the bearing can endure for 1 million revolutions. (Same as 23156RHA).
Static Load Rating (C₀)~3,800 kNThe maximum stationary load. (Same as 23156RHA).
Grease Limit Speed~850 rpmMaximum speed with grease lubrication. The adapter sleeve slightly reduces this compared to a direct mount.
Oil Limit Speed~1,100 rpmMaximum speed with oil lubrication.
Weight~105 kgApproximate 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.


Suffix Code Explanation (RHAK)

The suffix codes describe the bearing's features:

  • REnhanced Internal Design. Optimized geometry for higher load capacity and lower operating temperature.

  • HHardened Steel Cage. Provides superior strength and reliability under high vibration and shock loads.

  • AAsymmetric Roller Design. Offers higher performance and reduced friction compared to older symmetric designs.

  • KTapered 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.
