Types and Broad Applications of Advanced Self-Lubricating Bearings
To meet the demands of diverse operating conditions, the market offers various types of advanced self-lubricating and maintenance-free bearing solutions. Currently, the primary types that are technologically mature and widely used include:
Metal-Plastic Composite Bearings: Typically constructed with a metal backing (e.g., steel or bronze), a sintered porous bronze interlayer, and a surface layer impregnated with self-lubricating materials such as PTFE. These offer excellent low friction and wear resistance properties.
Cast Bronze Bearings: Utilizing a base of high-strength brass or tin bronze, these bearings achieve self-lubrication through embedded solid lubricants (like graphite or MoS₂) or by leveraging the inherent properties of special alloys. They are well-suited for high-load, low-speed applications.
Rolled Bronze Bearings: Formed by rolling specially formulated bronze alloy sheets. Their surface can feature indentations (oil pockets) or through-holes for grease retention, making them suitable for applications requiring supplemental grease or operating under boundary lubrication conditions. Solid lubricants can also be embedded.
Bi-metal Bearings: These feature a steel backing onto which a layer of wear-resistant bearing alloy (such as copper-lead or aluminum-tin alloys) is sintered. This combines the strength of steel with the anti-friction properties of the bearing alloy, commonly used for moderate to high loads and speeds.
Professional manufacturers typically adhere strictly to international or industry standards (e.g., ISO, DIN) during production, ensuring consistent product quality and performance stability. Furthermore, to meet specific equipment design requirements, many manufacturers offer custom manufacturing services based on client drawings or detailed specifications.
The application scope for these high-performance bearings is extremely broad, extending far beyond the heavy construction machinery like excavators and bulldozers discussed earlier. They play an indispensable role in a multitude of industrial sectors, including:
Heavy Industry: Metallurgical machinery, mining machinery, lifting equipment, port and marine machinery
General & Specialized Machinery: Textile machinery, construction machinery (other types), printing machinery, agricultural/forestry/water conservancy machinery, chemical machinery, food machinery
Automation & Equipment: Automation equipment, fitness equipment, etc.
Whether dealing with critical, high-load pivot points in construction machinery, precision movements in automated equipment, or harsh environments in mining and metallurgical machinery, selecting the appropriate self-lubricating or maintenance-free bearing significantly enhances operational reliability, reduces maintenance costs, extends service life, and contributes to cleaner, more efficient operations.
