23A1512270, 23A-15-12270 HUB KOMATSU

Transmission Hub for Komatsu Motor Grader Power Train Systems

The 23A1512270, 23A-15-12270 HUB KOMATSU is a Komatsu grader transmission component sold publicly as HUBand placed in transmission or power-train-related categories. Public listings connect this exact part number with Komatsu grader applications including GD505A-3, GD511A-1, GD521A-1, GD521A-1E, and GD525A-1C, while one Komatsu parts listing specifically places it in the transmission 1st and 2nd clutch section for GD505A-3 and another does the same for GD525A-1.

That matters because this is not a simple generic hub. The images show a large, heavy-duty transmission part with an internally splined center, a wide machined body, and an integrated outer toothed ring, which is consistent with a hub used inside a grader clutch or transmission assembly. The image-based description is an interpretation from the product photos, while the transmission/clutch placement comes from public parts pages.

At 3GEN Export, we supply 23A1512270, 23A-15-12270 HUB KOMATSU as an OEM supplier solution for buyers who need exact-number transmission parts for Komatsu graders. We deliver all over the world in 5 working days, helping workshops, resellers, contractors, and fleet owners reduce downtime when gearbox and clutch-related parts need fast replacement.

What Is 23A1512270, 23A-15-12270 HUB KOMATSU?

The clearest public naming for this part is simply HUB. 3GEN lists 23A-15-12270 Hub, 3GEN lists Komatsu HUB 23A-15-12270, and 3GENcalls it KOMATSU 23A-15-12270 HUB with the additional phrase Transmission Hub.

Public sources also place the part in a transmission setting rather than a cab, undercarriage, or hydraulic setting. One GD505A-3 parts page shows 23A1512270 / 23A-15-12270 in the power train transmission 1st and 2nd clutch section, and a GD525A-1 page shows the same number in the same transmission 1st and 2nd clutch area. 3GEN likewise markets it as a Transmission Hub for Komatsu grader models.

For your website, that gives a strong and safe product position: 23A1512270, 23A-15-12270 HUB KOMATSU should be described as a Komatsu grader transmission hub used in the 1st and 2nd clutch / power train transmission area of selected grader models.

Why This Hub Matters in Real Grader Operation

A transmission hub works at the center of torque transfer. In grader applications, especially inside clutch and transmission sections, parts like this help connect splined shafts and related gear or clutch members so the machine can transfer power smoothly under load. That functional explanation is partly based on the visible splined, toothed design in your images and partly on the public transmission/clutch placement of the part.

When a hub in this kind of assembly wears or is damaged, the transmission system may suffer from poor fitment, backlash, noise, or unreliable engagement. I am making that as a mechanical inference rather than claiming a published failure list, but it is the normal consequence of wear in a splined transmission hub. Since this part is explicitly sold for the transmission and clutch area, it should be treated as a precision replacement component rather than a simple cast part.

For buyers, that means replacing 23A1512270, 23A-15-12270 HUB KOMATSU can help restore tighter internal fit, more dependable torque transfer, and better service quality during grader transmission rebuilds.

Technical Details of 23A1512270, 23A-15-12270 HUB KOMATSU

Part Number Formats

This part appears publicly in both of these formats:

23A1512270
23A-15-12270

Using both formats on your page is important because sellers and buyers search both ways.

Product Name

Public sources identify the part as:

HUB
Transmission Hub

There is one conflicting 3GEN listing that titles the part as GEAR KOMATSU GRADER, but the stronger and more specific sources identify the same number as HUB, including model-level transmission pages and supplier pages. For a customer-facing page, HUB is the safer main product name.

Product Category

The strongest public category descriptions are:

Power Train / Transmission
1st and 2nd Clutch
Transmission Hub
Housing Parts

Visual Features Seen in the Images

From your images, this part clearly shows:

• an internally splined center bore
• a wide hub body
• an integrated external toothed ring
• multiple machined through-holes
• a thick, heavy-duty profile

These points come from the images, not from a published factory drawing. They support describing the item as a transmission hub designed for internal power-train engagement.

Weight in KG

I could not verify a reliable public KG weight for 23A1512270, 23A-15-12270 HUB KOMATSU from the accessible sources. One supplier page explicitly shows the weight as Undefined, and the others I found did not provide a trustworthy numeric value.

For your product page, the safest wording is:

Weight: please confirm before shipment.

I do not want to invent a number that the sources do not support.

Product Design and Working Characteristics

The design of 23A1512270, 23A-15-12270 HUB KOMATSU suggests a working transmission member rather than a passive support ring. The internal splines indicate shaft engagement, while the outer teeth indicate meshing or driven interaction with another transmission component. That is a mechanical interpretation from the images, but it matches the public classification of the part inside the transmission and clutch area.

This kind of part typically matters during gearbox rebuilds because correct spline fit, tooth condition, and concentricity affect the quality of the entire assembly. That is why a buyer searching 23A1512270 usually needs the exact component, not a near match.

For your site, that means the page should emphasize:

• exact OEM number searchability
• transmission hub function
• grader compatibility
• rebuild and service relevance
• fast worldwide supply from 3GEN Export
