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 23168RHAK bearing.
The KOYO 23168RHAK is a premium, high-performance Spherical Roller Bearing designed for mounting on a straight shaft using an adapter sleeve. The "RHAK" suffix combination signifies it is the top-tier version, featuring an enhanced internal design, a hardened steel cage, and includes the hardware for easy sleeve mounting. It is built for the most demanding heavy-industrial applications where extreme load, reliability, and simplified mounting are required.
The core dimensions of the bearing itself are defined by the 23168 standard. The adapter sleeve adds mounting-specific dimensions.
Parameter | Value | Description |
---|---|---|
Bearing Type | Spherical Roller Bearing with Tapered Bore & Adapter Sleeve | |
Shaft Diameter (d) | 340 mm | This is the nominal bore of the bearing itself. The actual shaft will be smaller. |
Outside Diameter (D) | 580 mm | The outer diameter of the bearing. |
Width (B) | 190 mm | The total width of the bearing assembly. |
Dynamic Load Rating (C) | ~3,300 kN | The radial load capacity. Slightly reduced from the straight-bore version due to the sleeve. |
Static Load Rating (C₀) | ~6,300 kN | The maximum stationary load. |
Grease Limit Speed | ~560 rpm | Maximum speed with grease. Reduced due to the adapter sleeve. |
Oil Limit Speed | ~700 rpm | Maximum speed with oil lubrication. |
Adapter Sleeve | H 2368 | The specific part number for the adapter sleeve. |
Shaft Size Range (with sleeve) | ~320 - 330 mm | The actual diameter of the straight shaft to be machined. This is critical. |
Weight | ~200 kg | Approximate total weight (bearing + sleeve + nut + washer). |
Note: The exact shaft diameter must be determined from KOYO's adapter sleeve tables for H 2368. It must be machined to a precise tolerance (e.g., h9 or h10).
This suffix set defines a premium bearing for adapter sleeve mounting:
R: Enhanced Internal Design. Optimized geometry (e.g., asymmetric rollers) for higher load capacity and lower operating temperature.
H: Hardened Steel Cage. Provides superior strength and reliability under high vibration and shock loads. A key feature for extreme-duty applications.
A: Asymmetric Roller Design. Offers higher performance and reduced friction compared to older symmetric designs.
K: Tapered Bore and Adapter Sleeve. This indicates the bearing has a tapered inner ring bore and is supplied as a set, including the adapter sleeve (H 2368), locking nut, and locking washer.
In summary: 23168RHAK = A top-tier spherical roller bearing with asymmetric rollers and a hardened cage, complete with an adapter sleeve for mounting on a straight shaft.
Simplified Mounting: The primary advantage of the "K" type. It allows for easy installation and removal on a straight, non-stepped shaft, reducing machining costs and simplifying maintenance.
Ultra-High Load Capacity: Designed to withstand the most severe radial loads and moderate axial loads.
Superior Robustness (H Cage): Ideal for applications with high vibration and impact loads.
Self-Alignment: Compensates for static misalignment (up to ~1.5-2.5°) from shaft deflection or mounting errors.
Pre-Interference Fit: The adapter sleeve allows for a precise and consistent interference fit to be achieved by tightening the locking nut.
This specific type of bearing is ideal for applications where shafts are straight and simplicity of maintenance is key, but operating conditions are extreme:
Conveyor Drive Pulleys (in mining, heavy aggregate)
Industrial Fans and Blowers (large ID fans)
Crushers and Screening Equipment
Large Pumps
Marine and Offshore Equipment
Vibrating Machinery
Shaft Preparation: The shaft must be machined to the correct diameter and tolerance specified for the H 2368 sleeve. The surface finish is critical.
Mounting: The bearing is positioned on the sleeve, and then the locking nut is tightened. This action drives the bearing onto the tapered sleeve, creating the necessary interference fit on the shaft.
Nut Tightening: Proper procedure is vital. It involves tightening to a specified torque or, more commonly, advancing the nut by a specific angle to achieve the correct internal clearance. Always follow KOYO's installation guidelines.
Locking: After tightening, the locking washer must be bent firmly into a notch on the nut to prevent it from loosening during operation.
Lubrication: The bearing, sleeve bore, and shaft must be properly lubricated before installation to prevent damage and ensure correct seating.
