A cement plant in the US was experiencing premature bearing failures due to contamination in its slurry pumps. Bearings were only lasting 2-3 months, leading to bearing replacement, downtime and maintenance costs of 96,616€ per year.
Cement plants are notoriously challenging in terms of their operational environment. Pumps with bearings not suitable for the conditions means more frequent failures and downtime.
Contamination entering the existing bearings was causing premature failure and unwanted costs.
NSK recommended replacing the previous, poor-performing bearings with TF Tough Steel Series Angular Contact Ball Bearings, which are ideal for use in demanding, heavily contaminated environments. The move has reduced costs by 56,176€, even when including the costs of providing NSK technical training to 10 customer employees in best-practice installation and maintenance techniques.
