23A6312101, 23A-63-12101 CYLINDER ASSY KOMATSU

The 23A6312101, 23A-63-12101 CYLINDER ASSY KOMATSU is publicly identified as a blade-lift hydraulic cylinder for Komatsu motor graders. Current public parts sources connect this number most clearly to GD510R-1 and GD511A-1 applications, and one catalog listing gives a reference weight of 36.9 kg. Seller listings also place it in the hydraulic system category, which matches the function suggested by the part name and the uploaded banner image.

From the banner image, this component has the expected visual profile of a heavy-duty hydraulic cylinder assembly: a long painted barrel, a rod-end connection point, a central mounting area, and a working layout suited to linear hydraulic movement rather than rotary transmission duty. That visual structure fits well with the public identification of the unit as a blade-lift cylinder used on Komatsu graders.

For buyers, this matters because a blade-lift cylinder is not a cosmetic or low-priority spare part. It is part of the hydraulic control chain that helps raise and position the grader blade during road work, leveling, trimming, and maintenance operations. When a cylinder in that role becomes worn, bent, leaking, or pressure-inefficient, the machine can lose lifting precision, response quality, and overall work consistency. That functional reading is supported by the public “blade lift cylinder” designation used by seller sources.

At 3GEN Export, we supply this part as an OEM supplier for professional buyers who need dependable sourcing, clear communication, and worldwide delivery in 5 working days.

Product Overview

The biggest advantage of this part number is that public sources already describe its role clearly enough to build a reliable product page. A Shop & Supply listing names it “Komatsu 23A-63-12101 Blade Lift Cylinder,” while an MTK Makina listing presents it as “23A-63-12101 Blade Cylinder Assy Komatsu Grader GD511.” Together, those references point to the same conclusion: this is a grader blade-lift cylinder assembly rather than a general cylinder with an unclear application.

That clarity is important because the product name “cylinder assy” on its own can be too broad for serious buyers. Heavy machinery contains many cylinders for steering, articulation, blade shift, drawbar shift, ripper, scarifier, and lifting functions. Public sources reduce that ambiguity by identifying this number specifically with blade-lift use. That makes the part much easier to position for search intent and much easier for buyers to match against the job they are actually doing.

The 23A6312101 / 23A-63-12101 number also appears in both hyphenated and non-hyphenated forms across public listings. That matters for SEO because buyers often search in different ways depending on whether they are reading a printed catalog, copying a warehouse label, or using an ERP system. A strong product page should naturally support 23A6312101, 23A-63-12101, and the spaced format 23A 63 12101 without forcing those variations unnaturally.

What This Cylinder Does

A blade-lift cylinder converts hydraulic pressure into linear force so the grader blade can be raised, controlled, and held at the required position during work. Public seller sources label this exact part as a blade-lift cylinder, which means its job is directly tied to the vertical control of the moldboard or blade assembly rather than to steering or articulation.

In practical field use, that function is critical. A motor grader depends on controlled blade height to cut, spread, shape, and maintain surfaces accurately. If the lifting cylinder does not respond smoothly, hold pressure properly, or extend and retract under load as intended, grading precision starts to suffer. That affects not only finish quality but also operator confidence and jobsite productivity. This is a practical mechanical inference from the documented blade-lift role of the part.

A cylinder assembly in this position must do more than move. It must resist seal wear, handle repeated hydraulic cycles, remain straight under working load, and maintain internal pressure efficiency over time. That is why buyers looking for 23A6312101 or 23A-63-12101 are usually doing real repair work, not speculative browsing. In most cases, the machine is already showing a hydraulic issue or the workshop is already planning a component replacement.

Visual Analysis of the Uploaded Banner

Even though the image is presented as a banner rather than a neutral catalog photo, it still gives useful mechanical clues.

Long hydraulic barrel

The main body appears as a long cylindrical barrel painted in Komatsu-style yellow. This shape is typical of a hydraulic cylinder housing built to contain oil pressure and guide the piston assembly through repeated extension and retraction cycles. That visual structure aligns with the public identification of the part as a hydraulic blade-lift cylinder.

Rod-end connection profile

At the upper end, the component shows a connection profile consistent with a mounted working end rather than a pump drive or rotating gear element. That is exactly what buyers expect from a cylinder assembly used to transfer lifting force into a blade-control linkage or supporting mount.

Mid-body mounting area

The visible side mounting point and central body proportions suggest that this part is designed to sit in a fixed working position while delivering controlled linear movement. In hydraulic systems, that kind of layout is typical when the component must remain structurally stable while transmitting repeated lifting force.

Heavy-duty industrial finish

The painted outer surface, solid barrel proportions, and straightforward industrial geometry all support the same commercial message: this is a high-duty Komatsu grader hydraulic component meant for real field service, not a light accessory item.

Compatible KOMATSU Models

The strongest publicly confirmed machine references I found are:

• Komatsu Motor Grader GD510R-1

• Komatsu Motor Grader GD511A-1

An additional seller listing ties the same part number to “Komatsu Grader GD511,” which reinforces GD511-family use.

There are also broader public references that associate 23A-63-12101 with other grader families, including GD521A, GD611A, GD621A, GD621R, GD623A, GD661A, GD663A, and even GS360 in some listings. However, these broader results are not as cleanly documented as the GD510R-1 and GD511A-1 references, and some public data for neighboring grader models points to different blade-lift cylinder numbers in certain serial ranges. Because of that inconsistency, I would not present the wider list as fully confirmed fitment without serial verification.

For your product page, the safest and most trustworthy wording is:

Confirmed public references

• GD510R-1

• GD511A-1

Additional public marketplace references

• GD511 family

• Some broader grader-family listings mention GD521A, GD611A, GD621A, GD621R, GD623A, GD661A, GD663A, and GS360, but these should be checked against serial number before order.

That phrasing keeps the page strong for search while staying honest about what is firmly supported and what is only partially supported by public listings.

Weight of 23A6312101, 23A-63-12101 CYLINDER ASSY KOMATSU

A current public Komatsu parts catalog listing gives the weight of this part as 36.9 kg. That is the most defensible standalone weight figure I found from public sources.

One public 3GEN Export listing shows 38 kg, which is close but not identical. Because those two public figures are near each other, the most honest website wording is:

Approximate weight: 36.9 kg

or

Approximate weight range: 36.9–38 kg

For a clean product page, I would use 36.9 kg as the primary published weight and note that final packed weight may vary depending on packaging.

Why This Part Matters in Real Grader Work

A blade-lift cylinder matters because the grader blade is the machine’s working edge. If the blade cannot be raised, lowered, or held with precision, the entire machine becomes less effective. Public seller references identify this exact part number as the blade-lift cylinder, so its relationship to blade control is not speculative.

In real operating conditions, that means this component affects finish grading quality, leveling consistency, road shaping accuracy, and general machine response. A cylinder that leaks, drifts, binds, or loses hydraulic efficiency can turn a normally precise grader into a machine that wastes operator time and delivers uneven results. This is a practical performance inference grounded in the documented blade-lift function of the part.

That is also why buyers should not treat this as a minor spare part. The cost of the component is only one part of the decision. The real cost lies in downtime, delayed work schedules, repeat repairs, and lost confidence in the hydraulic system. For contractors and fleet managers, replacing the correct cylinder early is often far less expensive than allowing a hydraulic control problem to spread into a larger service event.

Buying Guidance Before Ordering

A strong e-commerce page should help the customer avoid mistakes before checkout.

Use both part-number styles

Support both 23A6312101 and 23A-63-12101 on the page. Public listings use both formats, and buyers search both ways.

Match the function, not just the number

This part is publicly described as a blade-lift cylinder. That matters because graders have many hydraulic cylinders serving different functions. A buyer should confirm the machine needs the blade-lift cylinder specifically, not a drawbar-shift, blade-shift, or articulation cylinder.

Confirm model and serial number

GD510R-1 and GD511A-1 are the strongest confirmed public applications. Wider public references exist, but model-to-model and serial-range differences appear in the broader grader family, so serial verification remains the safest final step.

Compare visually with the removed part

The uploaded banner shows enough of the body shape and connection style to help a workshop compare the old part before ordering. That kind of visual check reduces returns and shortens downtime.
