In 2009 a specialty aggregate quarry on a 1,000-acre site on the shores of Lake Huron approached us with a problem
The very hard, durable nature of trap rock put a lot of strain on their conveyor belts, and would wear out the cheap metal steel and plastic side guide rollers that keep the belt in alignment after a few months.
Make a product with high quality steel, case hardened to last 10x longer than OEM products
Make it last even longer by adding dust covers the protect the inner bearings. The result is a patented heavy-duty guide roller that won’t wear out and will protect the leading edge of the conveyor belt for years.
