Solutions With GRAPHALLOY® 4-Bolt Flange Inserts

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.

Bearing Problems in Overhead Conveyors

A heat treat company was experiencing bearing problems with their overhead conveyor. They had high maintenance costs and lost production due to weekly bearing lubrication. Ball bearings, brass and bronze bearings were tried with no success.

GRAPHALLOY® Bushings and Thrust Washers were installed, generating annual savings of more than $15,000 in weekly maintenance costs alone.
