Buyer Answer
What construction equipment castings can JK Casting review?
JK Casting reviews custom construction and heavy equipment castings and machined parts for equipment OEMs, repair teams, and replacement-part buyers. Typical RFQs include hubs, bearing housings, gearbox and drivetrain housings, brackets, mounts, linkages, and covers made from buyer drawings, 3D files, samples, or worn-part evidence. Carbon steel, ductile iron, and grey iron are our regular material families. Material suitability and the manufacturing route are reviewed for each part; stainless steel and other special grades require separate feasibility confirmation. Every project is checked before quotation.
- Buyer need
- New OEM parts, second-source projects, repair parts, and discontinued replacements.
- Evidence accepted
- 2D drawings, 3D files, physical samples, worn-part photos, and application details.
- Quote basis
- Material, quantity, machining, coating, duty, inspection, packing, and delivery requirements.
Bucket Tooth Geometry
Bucket Teeth by Size and Working Conditions
Compare compact, medium and large general-purpose profiles with teeth for penetration, rock, soft ground and loading. Send your drawing or measured sample so we can review geometry, adapter fit and the intended duty together.
Compact General-Purpose
General digging and loading. Define the overall length, cutting-edge width and adapter fit for a compact tooth.
Medium General-Purpose
General earthmoving. Match tooth size to the adapter and bucket; include pin position and the required material.
Large General-Purpose
A larger general-purpose profile for digging and loading. Specify dimensions and duty; size alone does not establish rock suitability.
Rock Chisel
A narrow chisel profile for rock excavation. Define impact, abrasion, section thickness and the required heat treatment.
Single Tiger
A pointed profile for penetration in compacted ground. Identify soil conditions, tooth projection and wear requirements.
Twin Tiger
Twin points can provide corner clearance alongside single-point teeth. Confirm bucket position, point spacing and adapter fit.
Wide Flare
A broad edge for softer ground and a smoother trench floor. Check cutting width, adjacent-tooth spacing and side clearance.
Heavy-Duty Loader
A broad, thick wear profile for abrasive loading. Identify loader duty, underside wear allowance and the bucket-floor interface.
AI-generated geometry illustrations, not photographs of supplied parts. Size classes are visual references, not a dimensional catalog. Confirm exact dimensions, model compatibility, material, hardness and inspection requirements for your project.
Planning a production batch or repeat supply? Include your drawing or measured sample photos, tooth and adapter references, overall dimensions, pin and pocket details, ground conditions, required material and heat treatment, quantity per part number, and expected annual demand. We confirm project feasibility and the inspection scope before quoting.
Discuss a Bucket Tooth ProjectTypical Components
Cast Components for Construction Machinery
Use the categories below as a starting point. Final geometry, material, machining, coating, and inspection follow your drawings and operating conditions.
Bucket Teeth, Linkage & Pivot Parts
View bucket tooth profiles, alongside linkage parts, pivot bosses, and attachment components. Supply interface dimensions, load requirements, material, and wear-surface details.
Undercarriage & Track Components
Track guides, supports, and mounting brackets. Identify contact surfaces, hole positions, working clearance, and coating requirements.
Gearbox & Drivetrain Housings
Gearbox housings, covers, and carriers. Specify aligned bores, sealing faces, mounting datums, and the required supply condition.
Hydraulic Mounts & Brackets
Cylinder mounts, clevises, and support brackets. Provide pin interfaces, assembly clearance, load conditions, and inspection requirements.
Aftermarket Replacement Castings
Replacement castings for equipment rebuilders and parts suppliers. Include part references, sample measurements, batch size, and forecast repeat demand.
From Drawing to Delivery
A Manufacturing Path Built Around the Part
Material grade, casting method, machining sequence, surface treatment, and inspection are reviewed together. The factory certificate is held by Gaomi Changrong Precision Casting. The quotation defines any required heat treatment, coating, tests, and accompanying records.
1 / Casting & Material Control
Start with the Right Alloy and Casting Route
Review wall thickness, load paths, draft, and machining allowance through the sand and investment casting route. Material and the complete manufacturing scope are confirmed in the quotation.
2 / Precision Machining
Machine the Interfaces That Control Fit
Define bores, faces, threads, and mounting datums for CNC-machined castings, including which surfaces remain as-cast.
3 / Finish & Inspection
Prepare Parts for Real Equipment Duty
Agree coating, material records, packing, and the inspection and report scope before ordering, including the acceptance criteria for your part.
Faster Quotation
Send the Details That Define the Job.
For production or recurring supply, include the initial batch, expected annual demand, and delivery schedule. These inputs help compare tooling, machining, inspection, and packing costs across the program.
- 2D drawings, 3D files, or physical samples
- Material, surface treatment, and coating requirements
- Annual quantity, delivery plan, and inspection level
Part Definition
Part number, equipment model, drawing revision, and whether the project is new OEM production, a second source, or aftermarket supply.
Engineering Inputs
Material grade, load or duty cycle, fits and tolerances, and critical dimensions.
Manufacturing Scope
Casting, machining, coating, assembly requirements, initial batch, expected annual demand, and planned delivery batches.
Quality Needs
Inspection points, dimensional reports, packaging, and any project-specific acceptance criteria.
Component and Interface Review
Flanged hubs: define the bore, mounting face, and hole pattern
This component from our existing product gallery shows a stepped central opening, mounting holes, and machined faces. These are useful reference features when discussing a hub or housing for your equipment; the approved drawing establishes the actual application and fit.
- Bore and shoulder: identify the mating component, finished sizes, fits, and the drawing datum references.
- Mounting interface: supply the hole pattern, face requirements, and clearance around the assembly.
- Delivery condition: specify a raw casting, partly machined body, or finished component, with the required inspection records.
- Acceptance before repeat supply: mark the dimensions to be reported for sample approval, then agree batch identification, packing protection and repeat-order drawing control.
For a quotation, include material, drawing revision, quantity per part number and planned repeat batches. For steel parts, review our carbon steel casting or stainless steel project scope. A worn sample does not establish the intended finished dimensions.

Buyer FAQ
Construction Equipment Casting Questions
Direct answers for OEM, repair, and replacement-part buyers preparing a heavy equipment casting RFQ.
What construction equipment castings can JK Casting review?
JK Casting reviews drawing-based hubs, bearing housings, gearbox and drivetrain housings, brackets, mounts, linkages, covers, and other cast and machined parts when buyers provide drawings, 3D files, samples, or technical requirements.
Can JK Casting review replacement castings from a sample or worn part?
Yes. A replacement project can start from a physical sample, worn-part photos, equipment model, mating dimensions, and service information. Final feasibility depends on the available evidence, material, geometry, quantity, machining, and inspection requirements.
What information helps a heavy equipment casting quotation?
Send a 2D drawing or 3D model when available, plus material, quantity, critical dimensions, machining scope, coating, application or duty cycle, inspection requirements, and target delivery plan.
Is this a stock construction equipment parts catalog?
No. JK Casting supplies custom, drawing-based parts for OEM, repair, and replacement programs. Each RFQ is reviewed before quotation; listed part families do not confirm stock or automatic manufacturability.
