Hydraulic Support Fluid

Updated: 2026-09-13

Overview

Hydraulic Support Fluid is a specialized hydraulic oil designed for use in single hydraulic props, commonly employed in mining and construction industries. It plays a critical role in ensuring the smooth operation of hydraulic systems by reducing friction, preventing corrosion, and maintaining thermal stability. The fluid is formulated to withstand high pressures and extreme conditions, making it ideal for heavy-duty applications. Its properties include high viscosity index, anti-wear additives, and excellent thermal stability, ensuring longevity and reliability in demanding environments.

Physical and Chemical Properties

Hydraulic Support Fluid typically appears as a clear to pale yellow liquid with a density ranging from 0.85 to 0.89 g/cm³. It is insoluble in water and exhibits high thermal stability, making it suitable for use in high-temperature environments. The fluid's key chemical properties include anti-wear and anti-corrosion additives, which protect hydraulic components from degradation. Its high viscosity index ensures consistent performance across a wide temperature range, from sub-zero conditions to elevated temperatures encountered in mining operations.

Main Applications

The primary application of Hydraulic Support Fluid is in single hydraulic props used in mining and construction. These props rely on the fluid to transmit power, lubricate moving parts, and prevent corrosion. Beyond mining, the fluid is also used in other hydraulic systems requiring high-pressure resistance and thermal stability. Its anti-wear properties make it suitable for heavy machinery, ensuring minimal wear and tear on hydraulic pumps and cylinders.

Safety and Storage

Hydraulic Support Fluid should be stored in a cool, dry place away from direct sunlight to prevent degradation. Containers must be tightly sealed to avoid contamination and evaporation. When handling the fluid, personal protective equipment (PPE) such as gloves and goggles should be worn to prevent skin and eye contact. In case of spills, absorbent materials should be used to clean up the fluid, and proper disposal methods must be followed to comply with environmental regulations.

B2B Procurement Guide

When procuring Hydraulic Support Fluid, it is essential to verify its compatibility with the specific hydraulic systems in use. Look for certifications such as ISO 6743-4 to ensure quality and performance standards are met. Suppliers often offer bulk purchasing options, which can reduce costs. It is advisable to request samples for testing before committing to large orders. Additionally, consider the supplier's reputation, delivery timelines, and after-sales support to ensure a smooth procurement process.
