HC Machinery Parts is the export operation of Guangzhou Jiaying Mingdong Machinery Equipment Co., Ltd — specialized in excavator hydraulic parts: hydraulic pumps, swing motors, travel motors, hydraulic components, relief valves, electrical parts and seal kits.
Thousands of models are already cataloged and photographed. If you run excavators, we hold the part — or we find it.
Most "suppliers" you find online are traders forwarding your inquiry to someone else. Every model on this site is a part we actually catalog, photograph and ship — the picture you see is the unit you get, not a stock rendering.
Our warehouse keeps complete assemblies, rotary-group components and seal kits on the shelf for the machines that move the most: CAT 320/330, Komatsu PC200/PC220, Hitachi ZAX200/330, Doosan DH/DX, Volvo EC210/360, Sany SY and Hyundai R families.
Pumps and motors are inspected and pressure-checked before dispatch and leave with a test report. If a part surprises you on installation, our engineers answer on WhatsApp — the same people who packed it.
From complete swing devices down to single seal kits — one supplier, one shipment, one invoice.
Send a part number, a machine model, or just a photo of the nameplate.

Start from your excavator model — each page lists the hydraulic pumps, swing motors, gearboxes, travel reducers and seal kits we hold for that machine, with the OEM part numbers we cross-reference against.
