23B7072190, 23B-70-72190 BUSHING KOMATSU

Product Overview

The 23B7072190, 23B-70-72190 BUSHING KOMATSU is a heavy-duty Komatsu replacement part identified in public parts references simply as a bushing and associated with several Komatsu motor grader applications. Public catalog sources list this part under the GD555, GD655, and GD675 grader families across several serial ranges, making it a relevant search and service item for grader maintenance, circle revolving systems, and related wear-point rebuild work.

When buyers search this part online, they usually use both formats: 23B7072190 and 23B-70-72190. For search performance, it is important to keep both versions in the content so the product can appear in searches from ERP systems, printed parts books, workshop job sheets, and marketplace lookups. Public listings also confirm the item as a Komatsu bushing and classify it within Komatsu spare parts catalogs and aftermarket inventories.

What Is 23B7072190, 23B-70-72190 BUSHING KOMATSU?

A bushing is one of the most important wear-control components in heavy machinery, even though it looks simpler than a shaft, gear, or housing. In practice, a bushing protects the surrounding assembly by supporting alignment, reducing metal-to-metal wear, managing surface load, and helping connected components move with controlled clearance.

Public Komatsu parts references identify 23B-70-72190 as a BUSHING and place it in grader-related sections such as Circle Drawbar, Circle Revolving and Circle Revolving Unit, Case, depending on machine model and serial range. That catalog placement strongly suggests that this part is used in the grader circle or revolving structure, where stable rotation, alignment, and wear resistance are essential.

the 23B7072190, 23B-70-72190 BUSHING KOMATSU appears to be a flanged cylindrical bushing with a broad upper flange and a machined inner sleeve surface. The color contrast and finish suggest a wear-oriented design with a metallic body and a precision-machined bearing surface. Based on the visible geometry, this part is suitable for applications where axial seating and radial support are both important.

Why This Komatsu Bushing Matters

A motor grader works under continuous vibration, shock loading, side load, dust exposure, and repeated articulation. In such an environment, a properly fitted bushing is not a minor item. It is a part that directly affects how smoothly the assembly operates and how long adjacent components survive.

In circle revolving and drawbar systems, bushings help maintain proper movement between loaded parts. If the bushing is worn, undersized, or poorly fitted, the result can be excessive play, uneven contact, abnormal noise, accelerated wear, and loss of dimensional control inside the working assembly. Over time, that kind of wear may damage neighboring bores, shafts, or housing surfaces and turn a manageable maintenance job into a major repair.

That is why buyers who know Komatsu grader maintenance often search by exact part number instead of searching only by generic description. Using the exact number 23B7072190 or 23B-70-72190 helps ensure the correct part is sourced for the correct machine family and assembly location.

Publicly Referenced KOMATSU Models

Public Komatsu parts references connect the 23B7072190, 23B-70-72190 BUSHING KOMATSU to multiple grader models and serial ranges. One detailed catalog source lists the following machinery for this part:

Confirmed public model references

• GD555-5 S/N 55001-UP
• GD675-5 S/N 55001-UP
• GD655-5 S/N 55001-UP
• GD655-6 S/N 60001-UP
• GD675-6 S/N 60001-UP
• GD655-7 S/N 65001-UP
• GD675-7E0 S/N 65001-UP
• GD655-5 S/N B40001-UP

The same source places the part in sections such as:

• Circle Drawbar, Circle Revolving (1/2)
• Circle Revolving Unit, Case

This is useful because it shows the part is not random or generic. It is tied to grader circle and revolving system assemblies in a traceable way. Still, because Komatsu fitment can vary by serial number, sub-configuration, and catalog revision, the best practice is to confirm the machine model and serial number before ordering.

Visual Inspection

Flanged design

The part has a wide flange at one end. This usually indicates that the bushing is designed not only to support radial movement but also to provide a positive seating face during installation. The flange can help control axial location and stop the component at a defined position inside the mounting point.

Precision-machined outer body

The outer cylindrical wall appears uniformly machined and finished, which supports a stable press-fit or seated-fit installation in a corresponding bore or housing.

Inner bearing surface

The inner side appears smooth and carefully finished, which is exactly what buyers want from a wear component that must work around a moving shaft, pin, or mating rotating surface.

Heavy-duty section thickness

This is not a thin sleeve. The wall thickness and flange size suggest that the 23B7072190, 23B-70-72190 BUSHING KOMATSU is meant for a loaded grader application rather than a light-duty pivot point.

Industrial wear-oriented construction

The overall shape indicates a robust wear component designed for service intervals, rebuild cycles, and harsh field environments rather than decorative or low-load use.

Function in Circle and Revolving Assemblies

Public catalog placement is the most important clue to how this part works. Because 23B-70-72190 appears in Circle Drawbar, Circle Revolving and Circle Revolving Unit sections, it is reasonable to describe its role in terms of alignment, support, and wear control within that grader structure.

In practical service terms, a bushing in this kind of assembly may contribute to:

Controlled movement

It supports the movement of one component relative to another while limiting uncontrolled friction and excessive looseness.

Dimensional protection

The bushing can act as a sacrificial wear interface, protecting more expensive neighboring parts such as housings, revolving structures, or mounting bores.

Alignment preservation

Correct fitment helps maintain proper relationship between the circle assembly and connected parts, which matters for blade positioning accuracy and consistent grader performance.

Serviceability

Replacing a worn bushing is generally far easier and more cost-effective than machining or replacing a larger surrounding structure. That makes the bushing a maintenance-critical component.

Load distribution

A flanged bushing can help spread contact loads across a larger seating face while still maintaining a stable bore for the moving or supported part.

Why 3GEN Export Is the Right Source
