Advantages of solid inlaid self-lubricating bearings

Published by HuiTong 2024-05-16

Solid inlaid self-lubricating bearings have holes of appropriate size and orderly arrangement on the metal friction surface of the bearing base, and then embedded solid lubricants with unique lubricating properties in the holes (the area of ​​solid lubricant is generally 25% of the friction area). -35%) and made of self-lubricating bearings.

The bearing combines the respective advantages of metal matrix and specially formulated lubricating materials, breaking through the limitations of general bearings relying on oil film lubrication. RCB solid inlaid self-lubricating bearings are especially suitable for oil-free, high temperature, high load, low speed, anti-fouling, anti-corrosion, anti-radiation, and special working conditions that cannot be lubricated by water or vacuum solution infiltration.

In the selection of the base material of the self-lubricating bearing (graphite copper sleeve), according to the main failure mode of the bearing, combined with the harsh and changeable characteristics of the use environment of construction machinery, and comprehensively considering factors such as material strength, corrosion resistance and adaptability, solid The base material of the self-lubricating bearings is high-strength brass with high bearing capacity, its allowable static bearing capacity is 250N/mmi, the allowable low-speed dynamic bearing capacity is 100N/mm', and it has good wear resistance.

The application of self-lubricating bearings (graphite copper sleeves) on excavators effectively simplifies the mechanical design, and has a simple structure and good manufacturability, which reduces the maintenance cost of the machine, and the quality disc is reliable, which helps to improve the performance of the whole machine. Work reliability. At the same time, the solid self-lubricating bearings has superior performance in use and strong product competitiveness, and it will definitely be more fully applied in the use of construction machinery in the future.
