Reduce downtime and increase efficiency with LOCTITE® 638 Industry Sector:
Situation
PRIMARY INDUSTRY
A cement manufacturer needed to repair a shaft on a large fan that had been damaged from a loose, spinning bearing. Repair of the shaft - from hardfacing to machining - would of taken five days. Hardfacing can also distort and weaken the shaft, and machining doesn’t always guarantee prevention of future fretting corrosion.
Application:
FAN SHAFT BEARING
Solution
Benefits
After removing and cleaning the main bearing, LOCTITE® 638 Retaining Compound was applied to the shaft, and the bearing was slipped into its proper position. Retaining compounds fills voids, preventing fretting corrosion and evenly distribute high load stress.
Maintenance was easily performed and the fan was up and running in eight hours - a large reduction in downtime from hardfacing and machining. Future damage to the shaft has also been prevented and the fit of the bearing maintained for its entire lifecycle.
