Large Gap Retaining : A limitation to Anaerobic Retaining Compound



LOCTITE Quick Metal 660 ( 22647 )  is designed for the bonding of cylindrical fitting parts, particularly where bond gaps can approach 0.50 mm (0.02 in.). The product cures when confined in the absence of  air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. This product possesses excellent gap cure characteristics. Typical applications include restoring correct fits on worn shafts, spun beraings, and damaged keyways.


However, any clearance greater that 0.50 mm, it is not recommended to apply Loctite 660. The gap allows the contact between the air and the retaining compound, being the nature of an anaerobic adhesive, it would not cure in the presence of oxygen.







You can make use of  LOCTITE  Steel Liquid 97483 or Devcon Steel Liquid 10210 for large gap retaining. However, it is not recommended for application in rotating equipments.
