Loctite LOC66040 Retaining Compound Press Fit Repair 660

Product Description

The LOCTITE LOC66040 is a retaining compound formulated for quick metal press fit repair, sold as Loctite 660. Retaining compounds in this class cure anaerobically between close-fitting metal surfaces, filling microscopic gaps to create a rigid, load-bearing bond. This product is designed for shafts, bearings, bushings, and cylindrical assemblies where a slip or loose press fit needs to be restored to close-tolerance performance without machining. Maintenance technicians, millwrights, and mechanical service professionals use retaining compounds like this one to extend component service life and avoid costly part replacement.

Loctite 660 is suited for industrial and commercial maintenance applications where metal-to-metal cylindrical fits have worn or are undersized. Typical scenarios include bearing-to-housing repairs, shaft-to-hub bonding, and sleeve or bushing retention. It is sold in individual units with a minimum purchase quantity of 10 units per order, making it appropriate for shop stock or fleet maintenance programs.

Key Features

• Anaerobic cure chemistry activates between close-fitting metal surfaces without air exposure
• Fills gaps in worn or undersized cylindrical fits, restoring structural integrity
• Designed for press fit repair on shafts, bearings, bushings, and hubs
• Eliminates the need for re-machining loose or worn metal fits in many applications
• Sold per each unit with a minimum order quantity of 10

Compatibility

Designed as an OEM-style retaining compound for metal cylindrical assemblies including shaft-to-bearing and housing-to-bushing applications in industrial and commercial maintenance settings.

Installation Notes

Application is typically performed by maintenance technicians or millwrights following lockout/tagout procedures with all equipment de-energized and stationary. Clean and degrease mating surfaces thoroughly before applying the compound to ensure full anaerobic cure. Allow adequate cure time before returning the assembly to service and applying load. Refer to the product technical data sheet for surface preparation and cure schedule guidance.
