Bearings, often regarded as the “heart” of industrial equipment, rely heavily on effective lubrication to maintain performance and service life. Traditional lubrication methods frequently suffer from oil film failure, high friction losses, and rapid component wear, leading to increased maintenance costs and downtime.

The oil-air lubrication system addresses these challenges through its advanced air-oil two-phase lubrication film technology. This innovative approach combines both hydrodynamic and hydrostatic lubrication characteristics. Compressed air acts as an “air spring”, distributing heavy loads and reducing localized stress, while micron-sized oil droplets form a uniform and durable oil film on friction surfaces. As a result, load-carrying capacity increases by over 50%, and the friction coefficient is reduced by 30–50%.

Real-world performance confirms these benefits. In one steel plant, the risk of oil film breakdown in rolling mill bearings decreased from 32% to 1.2%, while resistance to impact loads improved by 40%.

Another key advantage is the continuous micro-lubrication mechanism. With a precise supply of only 1.5–2 ml/h, the system ensures that the oil film remains constantly refreshed. At the same time, compressed air creates a positive pressure seal, preventing contamination and eliminating oxidation-related degradation common in traditional lubrication.

These combined advantages translate into a 3–6 times increase in bearing service life. Maintenance frequency is significantly reduced, unplanned downtime can drop by up to 60%, and lubricant consumption is as low as 1/50 of grease lubrication. In many cases, the system achieves a return on investment within 6 to 12 months, making it a powerful solution for improving industrial efficiency and cost performance.

In these industrial scenarios, oil air lubrication is the preferred choice
