Guangzhou Zhonghai Jiuchuan Machinery Equipment Co., Ltd. supplies excavator lubricants for the hydraulic systems, diesel engines, final drives, swing drives, pins, bushings, bearings and other lubrication points of construction machinery.
Our excavator lubricant range is divided into two main categories:
Lubricating Oil
Lubricating Grease
Excavator lubricating oil is used in systems where the lubricant must circulate, transfer power, dissipate heat or protect enclosed moving components.
Depending on the excavator design, lubricating oil may be required for:
Hydraulic pumps and valves
Hydraulic cylinders and motors
Heavy-duty diesel engines
Final drives
Travel reduction gearboxes
Swing reduction gearboxes
Enclosed gear systems
Applicable transmissions and auxiliary systems
Using the correct excavator lubricating oil helps maintain a stable lubricating film, control wear, carry heat away from working components and protect metal surfaces against rust and corrosion.
Excavator lubricating grease is used where oil cannot remain reliably at the contact surface or where the joint requires a lubricant with stronger adhesion and sealing ability.
Typical excavator grease points include:
Boom foot pins
Boom cylinder pins
Arm and boom connections
Bucket linkage
Bucket pins and bushings
Attachment connection points
Swing bearing grease points
Applicable support bearings
Manual and automatic lubrication systems
Pins and bushings operate at relatively low speed but under high load, repeated shock and oscillating movement. The grease must remain between the metal surfaces instead of being quickly displaced by pressure, water or contamination.
Selecting an excavator lubricant by price or product colour alone can result in poor lubrication, difficult cold starting, excessive heat or premature component wear.
Use the following selection process.
Confirm whether the product is required for:
Engine
Hydraulic system
Final drive
Swing gearbox
Pins and bushings
Swing bearing
Centralized lubrication system
Another specified component
The excavator maintenance manual may specify:
SAE viscosity grade
ISO viscosity grade
API performance category
Gear-oil classification
NLGI grease grade
OEM fluid standard
Permitted temperature range
The required standard is more important than the general product name.
Cold weather requires sufficient low-temperature flow and pumpability. High ambient and component temperatures require the lubricant to maintain viscosity and resist oxidation.
Provide both the minimum and maximum operating temperatures when requesting technical selection assistance.
Excavators used in mining, quarrying and demolition normally experience greater impact and loading than machines performing light landscaping or municipal work.
Operating hours, digging intensity, travel frequency and attachment type should all be considered.
Mud, rain, washdown water and airborne dust can affect lubricant performance.
Wet applications may require stronger water resistance and corrosion protection. Dusty applications require careful storage, clean handling and effective filtration to prevent abrasive contamination.
Do not mix lubricants solely because they have the same viscosity or NLGI grade.
Different products may use different:
Base oils
Additive packages
Grease thickeners
Performance standards
Seal-compatibility characteristics
When changing lubricant type, consult the machine manual or lubricant supplier regarding draining, flushing and grease compatibility.
Our excavator lubricant supply service can support lubrication requirements for:
Mini excavators
Compact excavators
Crawler excavators
Wheeled excavators
Long-reach excavators
Mining excavators
Demolition excavators
Material-handling excavators
Forestry excavators
Amphibious excavators
The oil capacity, lubricant specification and grease demand vary substantially between a compact excavator and a large mining machine. Model information should therefore be included with every enquiry.
We understand excavator operating systems, replacement parts and maintenance requirements, allowing lubricant selection to be connected with the actual machine application.
Customers can coordinate lubricants together with undercarriage parts and other construction machinery components, simplifying supplier management and shipment consolidation.

Our team reviews the excavator model, lubrication position, existing specification and operating environment before recommending a supply option.
Our warehouse supports organized product storage, order consolidation and preparation for overseas shipments.
A multilingual foreign-trade team provides support for product confirmation, export documents, customs-clearance coordination and after-sales communication.
Service in 12 languages helps distributors and equipment companies communicate technical and purchasing requirements more efficiently.
Our Guangzhou location provides access to a mature construction machinery supply chain, supporting the consolidation of lubricants, components and related maintenance products.
Correct lubrication helps protect hydraulic components, engines, gears, pins and bushings from premature wear and unplanned downtime.
Guangzhou Zhonghai Jiuchuan Machinery Equipment Co., Ltd. combines construction machinery knowledge, warehousing resources, multilingual communication and export services to support overseas excavator lubricant purchasing.
Send us the excavator model, lubrication point, required grade and purchasing quantity. Our team will review the information and prepare a matched supply proposal.
