640™ is designed for the bonding of cylindrical
fitting parts. The product cures when confined in the absence
of air between close fitting metal surfaces and prevents
loosening and leakage from shock and vibration. Typical
applications include retaining keys and splines, eliminating
backlash in worn assemblies, retaining bearings in place -
preventing spin out, retaining rotor to shafts in fractional and
subfractional horsepower motors, retaining bushings and
sleeves in housings and on shafts, augmenting press fits,
restoring the fit to worn assemblies or out of tolerance parts.
