Oil air lubrication can extend bearing life by 3-6 times, which is not an exaggeration, but stems from its scientific technical principles and practical verification.

As the "heart" of industrial equipment, the lubrication quality of bearings directly determines their operational stability and lifespan. Oil-air lubrication, through its three core advantages, completely solves the pain points of traditional lubrication.

The key to extended lifespan is the gas-liquid two-phase film technology. The special film structure formed by oil-air lubrication possesses both hydrodynamic and hydrostatic characteristics. Compared to traditional lubrication, the probability of oil film formation is increased by 70%, the thickness can be 2-3 times, and the load-bearing capacity directly jumps by 50%.

This strong and tough oil film acts as a robust barrier, effectively buffering mechanical impacts and reducing the coefficient of friction by 30%-50%. Data from a steel plant shows that the risk of oil film rupture in rolling mill bearings decreased from 32% to 1.2%.

Fresh lubrication supply builds long-term protection. Through precise control, the system delivers a small amount of lubricating oil to the lubrication point in the form of continuous droplets, ensuring that the oil-air film inside the bearing housing remains fresh at all times, fundamentally preventing component wear caused by lubricating oil aging and deterioration. Practice has proven that using oil-air lubrication can extend the bearing oil change cycle to over one year and reduce the failure rate by 80%.

Compressed air provides both cooling and protection. As a natural coolant, compressed air can quickly remove the heat generated by bearing operation, reducing the bearing temperature rise by 20-30°C, up to a maximum of 150°C. Simultaneously, the 0.1-0.3 bar positive pressure it creates within the bearing housing effectively prevents the intrusion of impurities such as iron oxide scale and cooling water, significantly improving the bearing's anti-contamination capability.

This triple advantage synergistically has led to the widespread acceptance of oil-air lubrication in various operating conditions. From heavy-duty conditions to high-temperature environments, oil-air lubrication demonstrates a stable lifespan extension effect, with practical applications verifying the feasibility of a 3-6 times increase in lifespan.
