Specialist bearings manufacturer SKF recently supplied the SKF Explorer series large roller bearings for a vertical roller mill used in the production of cement. Following a routine maintenance check, a long-standing SKF customer in the cement and concrete industry determined that the bearings on one of its vertical roller mills needed replacement. The SKF Explorer series was suggested as the optimal solution.

SKF Explorer bearings supplied for vertical roller mill“These bearings feature optimisation of the internal design, high performance materials and heat treatment. These properties result in a greater wear resistance, lower operating temperatures and longer service life even under contaminated or poor lubrication conditions. This translates to improved availability and productivity,” says SKF Territory Sales Manager, Sean Weir.

“Operating in an extremely demanding environment, the vertical roller mill is critical in the production process of the cement producing facility. It was therefore crucial that the bearings are of superior quality to deliver reliable performance and maximise productivity for the customer. That’s why the SKF Explorer series bearings were proposed.”

However, SKF Europe was only able to provide a delivery time of six months. This was not an option for the customer, which considered the risk exposure too high. “As one of our loyal key customers who use a wide range of SKF products we had to pull out all the stops in order to come up with a better solution,” Weir says.

“SKF South Africa solicited support from the SKF mining segment team and we were consequently able to reduce the delivery time from SKF Dalian factory in China by 1.5 months to the satisfaction of our customer.”

The bearings condition is being closely monitored until a maintenance event can be scheduled. “Both the engineering company that overhauled the mill as well as the customer valued our knowledge and expertise. In addition to strengthening their confidence in SKF as a partner, our ability to assist the customer has opened up many other opportunities for collaboration and engagement in other projects between the customer and our authorised distributor also,” Weir concludes.
