Hilman 8-XYS Modified Chain Action Rollers were used as a thermal expansion bearing for a Combined Feed Heater at Suncor Energy, Inc. in Ft. McMurray, AB Canada. These rollers were used day in and day out in a nasty, unforgiving environment. The original rollers lasted in this environment from 1999until 2017 when they were replaced during a shutdown. Hilman Rollers are known for their durability and this is just one example of our rollers being used for decades in harsh environments and getting the job done.
