bearing failure: why bearings fail & how you can prevent,bearing failure demands immediate attention because it can cost as much as $25,000-$50,000 per hour—in lost productivity, unplanned outages and downtime. what’s interesting, though, is that the bearing replacement itself is almost always the cheapest part of the failure. a $50 bearing can take down a multi-million-dollar process..conveyor belt common problem trouble shooting guide 1,6. belt runs to one side for a considerable distance, or the entire conveyor. a. the belt is running off centre as it comes around the tail pulley and/or through the load point. re-track belt, install training idlers on the return prior to the tail pulley. b. build up of material on idler rollers. clean and maintain. install scrapers, brushes.
