The true cost of downtime in cement operations: Dagmita and NSK reliability solutions
NSK has contributed to the growth of many industries and the advancement of mechanical technology. With more than 100 years of experience and a broad portfolio of products and services, NSK delivers solutions that meet application requirements and high quality standards.
As an NSK partner, Dagmita supports industrial customers in selecting solutions that reduce unplanned downtime and improve reliability. In cement related applications, contamination, abrasives and vibration are among the most common drivers of premature bearing failures. Below are practical examples where the solution started with failure analysis.
Concrete pipe cutting and dust contamination
NSK engineers performed a detailed failure analysis and application review. Traditional deep groove ball bearings could not withstand abrasive concrete dust. Dust contamination degraded the lubricant and directly caused premature failures. Before the solution, failures occurred every 8 to 12 weeks and each incident resulted in around 8 hours of unplanned downtime. NSK Molded Oil technology is designed to enhance performance and reliability in harsh dusty environments.
Cement slurry pumps and rising maintenance costs
A leading cement plant in the United States faced repeated stoppages and increasing maintenance costs due to early slurry pump bearing failures. In harsh conditions with contamination, bearing life was only 2 to 3 months. NSK engineers identified contamination as the key factor. NSK recommended angular contact ball bearings produced from high toughness HTF steel, engineered to withstand extreme operating environments and increase resistance to wear, contamination and fatigue.
Vibration intensive environments
A paving manufacturer in Poland experienced frequent failures in a vibration compaction machine. In four months, motor bearings failed 10 times, and each replacement required at least 2 hours of downtime. In such applications, bearing technology and correct selection based on real conditions are critical.
