Problem: The OEM supplied steel carry rollers that supported the steel cable. Over time, this created metal fretting; which caused the steel cable to fray.
Solution: Given the large and heavy steel cable, we needed to create a rolling surface with dissimilar materials. With the assistance of our factory engineers, we designed a solid steel roller mounted on pillow block bearings and cast with a 95A 1/2″ thick urethane. With this harsh application, something is going to wear over time; the idea was to make the rollers absorb the wear and not the expensive steel cable.
