BELPARTS MACHINERY LIMITED Factory Tour

Precision Manufacturing, Fully Traceable

From raw material to finished product — every Belparts hydraulic component is manufactured, tested, and traced under one integrated quality system.

Raw Material & Heat Treatment

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.

Precision Machining

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.

OEM & ODM: Built Around Your Fleet

Broad OEM-based compatibility, flexible customization, and fast turnaround — built to reduce your inventory burden and adapt to your exact appliion.

Cross-Model Compatibility by Design

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.

Customization Capabilities

• Custom final drive and travel product dimensions tailored to specific client requirements and appliion scenarios
• One-on-one service coordination from design through delivery
• Mass customization orders completed within 45 days
• Proven track record serving customers across global markets

Model Coverage

Why OEM/ODM with Belparts

• Reduced Inventory Complexity — Universal-fit design across multiple machine models means fewer part numbers to stock.
• Fast Turnaround — Mass customization completed within 45 days from confirmation to delivery.
• Direct Engineering Support — One-on-one technical coordination ensures the customized product matches your exact appliion.
• Global Track Record — Trusted by customers worldwide for both standard and non-standard part development.

Genuine Original-Brand Parts Sourcing

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.
