Oil–Air Lubrication Explained: From Principle to Industrial Application
Release time:
2025-12-17
For those new to oil–air lubrication, this article offers a quick overview of one of today’s most efficient industrial lubrication technologies.
Oil–air lubrication works by mixing a precise amount of lubricant with compressed air to create a stable oil–air flow. The lubricant is delivered as fine oil droplets through pipelines directly to friction points, ensuring accurate and continuous lubrication.
Unlike conventional systems, oil–air lubrication is not limited by lubricant viscosity. It can reliably deliver light oils, semi-fluid greases, and even specialty lubricants containing a high percentage of solid additives, making it ideal for demanding operating conditions.
This technology is widely used on rolling bearings, drive chains, wheel flanges and rails, high-temperature crane components, and open gears, where reliable lubrication is critical.
In industrial applications—especially in the steel industry—oil–air lubrication has proven highly effective. It is commonly applied to roller table bearings on billet and slab continuous casting machines, rolling mill bearings in bar and wire rod lines, high-speed wire rod equipment, and key transmission points in strip mills. Precise oil delivery minimizes waste, reduces failure rates, and significantly extends maintenance intervals.
With its high efficiency, strong adaptability, and proven performance, oil–air lubrication is becoming a preferred solution for companies seeking long-term equipment reliability. For operations limited by traditional lubrication methods, oil–air lubrication offers a practical and impactful upgrade.
