Hubs & Bearing Housings
Cast hubs, flanged housings, bearing carriers, and machined mounting interfaces.
Construction Equipment Parts
Cast and Machined Parts Built for Heavy Equipment.
JK Casting reviews cast and machined parts for excavators, wheel loaders, dozers, compact equipment, and repair programs. Send a drawing, 3D file, sample, or worn part; our Gaomi works checks material, load, fit, finish, inspection, and packing before quotation.

Typical Components
Parts Engineered for Demanding Machines
Use the categories below as a starting point. Final geometry, material, machining, coating, and inspection follow your drawings and operating conditions.
Bucket, Linkage & Pivot Parts
Load-bearing links, pivot arms, bosses, adapters, and attachment-side components.
Undercarriage & Track Components
Cast and machined supports, guides, brackets, and service-replacement components.
Gearbox & Drivetrain Housings
Rigid housings, covers, carriers, and precision-bored interfaces for drive systems.
Hydraulic Mounts & Brackets
Reinforced cylinder mounts, support brackets, clevises, and structural castings.
Aftermarket Replacement Castings
Reverse-engineered or drawing-based parts for maintenance, repair, and retrofit programs.
From Drawing to Delivery
A Manufacturing Path Built Around the Part
Material, casting method, machining sequence, surface treatment, and inspection are reviewed together - not as isolated steps. Casting, CNC machining, heat treatment, finishing, and inspection all run under one roof at an ISO 9001:2015 certified works held by our same-factory affiliate Gaomi Changrong Precision Casting.
1 / Casting & Material Control
Start with the Right Alloy and Casting Route
Review wall thickness, load paths, draft, machining allowance, and material requirements before production.
2 / Precision Machining
Machine the Interfaces That Control Fit
Bores, faces, threads, datums, and mounting features are processed to the drawing.
3 / Finish & Inspection
Prepare Parts for Real Equipment Duty
Coating, dimensional checks, in-house EN 10204 3.1 material reports, flaw detection, and packing follow the agreed project requirements.
Faster Quotation
Send the Details That Define the Job.
A complete inquiry helps engineering evaluate manufacturability, cost drivers, tooling, machining, inspection, and lead time more accurately.
- 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, sample condition, or target replacement application.
Engineering Inputs
Material grade, load or duty cycle, fits and tolerances, and critical dimensions.
Manufacturing Scope
Casting, machining, surface treatment, painting or coating, and assembly requirements.
Quality Needs
Inspection points, dimensional reports, packaging, and any project-specific acceptance criteria.
Application Coverage
Built Around Real Equipment Duty Cycles
The same component can face very different loads depending on machine size, terrain, attachment, maintenance practices, and operating hours. Quote the application - not only the shape.
For replacement projects, include the machine model, failed-part photos, mating dimensions, and any known service issues.
