How Effective Is Oil-Air Lubrication? Can 1.5 ml/h Really Ensure Proper Lubrication?

A common question in industrial lubrication is: Can a low oil consumption of just 1.5 ml/h truly meet equipment lubrication needs? To answer this, it’s important to understand the fundamental principle of lubrication.
The Core Principle of Lubrication
The purpose of lubrication is to form a protective oil film between two moving surfaces, preventing direct contact and reducing wear. For components such as bearings, the key factor is not the total oil volume, but whether a stable and continuous oil film can be maintained.
As long as this oil film is properly formed, effective lubrication can be achieved—regardless of how small the oil supply may seem.
Why Micro-Lubrication Works
In an oil-air lubrication system, a supply rate of 1.5 ml/h can be sufficient to maintain the required oil film under appropriate conditions. This is possible because the system delivers precise, continuous, and evenly distributed micro-quantities of lubricant directly to the lubrication point.
Key Advantages of Oil-Air Lubrication
- Precision and energy efficiency: Oil is supplied exactly as needed, avoiding both over-lubrication and under-lubrication
- Reduced oil consumption: Significant savings compared to conventional lubrication methods
- Cleaner operation: Minimal oil leakage helps maintain a clean working environment
- Extended equipment life: Stable lubrication reduces friction and wear, lowering failure rates
- Automation-ready: Supports remote monitoring and precise control, reducing maintenance workload
Flexible Adjustment for Real Applications
It is important to note that 1.5 ml/h is a reference value. In practice, oil supply should be adjusted based on factors such as bearing size, operating speed, load, and temperature to ensure optimal performance. By focusing on oil film quality rather than oil quantity, oil-air lubrication delivers highly efficient, reliable, and cost-effective lubrication for modern industrial applications.
