LOCTITE 680 Retaining Compound : Simple Fixing, Reliablity Guaranteed






LOCTITE® 680™ ( 23416 ) is designed for the bonding of cylindrical fitting parts, particularly where low viscosity is required. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration.



An oleo -  chemical with edible oil refinery plant located in Pasir Gudang had a partial shutdown. One of the air blowers faced a bearing loosening problem and had no choice to stop the operation. One of the four bearings had  to be changed.

Fixing a new bearing to the housing and shaft  could not solve the problem due to a small gap in between bearing and bearing housing. To solve this problem with conventional method like rebuilding the bearing housing, metal spraying found to be not feasible. Costing was one issue, and taking few days to complete was another greater issue.


Loctite Engineer, En Saharudding was invited to tackle the problem. Loctite 680 was later proposed to fix the bearing. 




" Applying the Loctite 680 to the bearing housing and the shaft; the surfaces to be treated were first cleaned with Loctite ODC Free Cleaner  & Degreaser 22355 "



" Applying the Loctite 680 to the bearing "




" The bearing is being fixing into the housing "


One would be surprised by this simple solution compared to the conventional methods, in terms of  time spent, and the cost involved. Less than half bottle of Loctite 680 was used, and certainly less than Ringgit Malaysia 50.00  or USD16.00 was spent.
