The mill used set screws to hold its bearings on a shaft, but the screws sometimes loosened. This caused the roller bearings to spin on the shaft, leading to damage and up to 10 hours of costly repair time for every incident.
Henkel Adhesive Technologies’ LOCTITE® team selected LOCTITE® 222™ to rectify the issue. Once the bearing set screws were cleaned, the solution was applied, filling the gap between bearing and screw and through hole. Metal set screw ions aid the curing process, helping create a hard fixed thermoset plastic.
