LOCTITE 660 is a strong component adhesive with good filling properties designed for bonding cylindrical parts with increased clearance. It is therefore well suited for repairs of worn-out parts such as bearing seats, keys, keyways, tapered connections, worn shafts and twisted bearings, without the parts needing machining. This product cures in the absence of air when sealed between closely fitting metal surfaces, preventing loosening and leakage due to shock and vibration. Its excellent curing characteristics also make it suitable for filler plates. Show more
