Polyurethane improves safety in mills

In a steel or aluminum mills, safety is always a major concern. With many employees staying in the workforce longer, there is a growing concern for reducing injuries that result from heavy lifting.

Recently, an aluminum mill established a goal to limit the maximum weight lifted manually at 50 pounds. In the roll shop this was a major concern because the bearings are held in place by a large steel split ring, known as a thrust collar that is locked into place. The maintenance process of changing out the bearing requires the worker to break the ring free and remove it. These rings can typically weigh more than 60 pounds each.

Interestingly, Kastalon was able to design a custom engineered polyurethane alternative that had all of the same strength and wear characteristics of the steel ring, but only weighed 12 pounds.

The first 4 rings well exceeded the life expectancy by lasting more than a year in continuous service and proved to reduced lost time due to back injuries in that area.

Not only did the mill find a method that would protect their workforce from unsafe practices but also found a way to achieve greater efficiency.
