Pulp & paper mills: eliminate set screw loosening

A paper mill sought a solution to prevent set screw loosening on sticker wheels and prevent downtime and costly repairs.


How to ensure set screws remain set?


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.

LOCTITE® 222 eliminates downtime


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.
