High temperatures were causing premature failures of 4-bolt flange bearings in this glass manufacturer’s lehr. Bearings had to be heavily greased in an attempt to keep them running.
Unfortunately, the excessive use of grease was causing a safety and fire hazard. Chronic failures were still occurring, resulting in frequent down time and lost production.
An economical solution was found by retro-fitting the existing housings with GRAPHALLOY® 845 Series Inserts. The inserts have now lasted more than a year without a single failure or need for replacement. Using GRAPHALLOY 4-Bolt Flange Inserts has saved this company over $150,000 to date.
