Belparts Machinery Limited — Your Trusted Partner in Excavator Hydraulic Parts
Founded in September 2013 and headquartered in Guangzhou, China's premier engineering machinery hub, Belparts has grown into an integrated manufacturer and global exporter of excavator hydraulic components. Backed by our own production facility and a network of specialized manufacturing partners, we combine in-house engineering control with flexible supply chain capacity — giving customers both high quality and competitive lead times.
Our core product range covers the full hydraulic system — engineered and manufactured to deliver reliable performance across every major excavator brand and model.
In addition to our own manufactured and premium aftermarket products, Belparts maintains established supply chain channels to source genuine original-brand hydraulic components — including brands such as Rexroth, Nachi, Eaton, Kawasaki, NABTESCO, and KYB (Kayaba) — for customers who require original manufacturer parts.
For over a decade, the "Belparts" brand has earned the trust of customers across North America, South America, Europe, Africa, the Middle East, Southeast Asia and Oceania.
From precision manufacturing to face-to-face customer relationships around the world — our factory floor and our trade show booth tell the same story of quality and trust.

Our commitment goes beyond the sale — a professional technical team, a complete part-number cross-reference system, and a comprehensive after-sales support structure ensure every customer gets the right part, the first time. We continue to invest in technical expertise, product quality, and long-term partnerships — building a business built on trust, reliability, and mutual growth.
Broad OEM-based compatibility, flexible customization, and fast turnaround — built to reduce your inventory burden and adapt to your exact appliion.
Belparts hydraulic pumps, travel motors, and swing motors are developed and refined based on original OEM specifiions — engineered so that a single model can fit multiple excavator models. This cross- model compatibility reduces the number of SKUs customers need to stock, lowering inventory costs while maintaining reliable fitment across a broad equipment fleet.

In addition to our own manufactured and premium aftermarket products, Belparts maintains established supply chain channels to source genuine original-brand hydraulic components — including brands such as Rexroth, Nachi, Nabtesco, Kawasaki, Hitachi, Komatsu, Casappa, Toshiba, and KYB (Kayaba) — for customers who require original manufacturer parts. This gives customers a single-window option to source both cost-effective aftermarket alternatives and genuine original-brand parts through one trusted supplier.
From raw material to finished product — every Belparts hydraulic component is manufactured, tested, and traced under one integrated quality system.
All core components are forged from high-strength alloy steel (42CrMo grade), hardened to HRC 58-62 through carburizing (depth 0.8-1.3mm) and induction hardening (12-24 hours). Every incoming batch undergoes spectral analysis, Rockwell hardness testing, and flaw detection (UT/MPI) before entering production — with full raw-material-to- finished-product traceability.
Our facility runs CNC turning centers, gear grinders, and honing equipment achieving dimensional accuracy within ±0.01mm. Key processes include mirror-polished cylinder block/valve plate honing for hydraulic pumps, and fully automated gear-cutting lines (rolling → chamfering → gear-cutting → cleaning) for travel and swing gearboxes. In 2016, Belparts imported 200 sets of advanced production and testing equipment from Germany and Japan, forming an Automated Dust-Free Hydraulic Components Workshop.
