High-Strength Retention for Cylindrical Assemblies
\n
Loctite 638 Retaining Compound is a premium anaerobic adhesive formulated to secure cylindrical fitting parts exposed to shock loads, vibration, and demanding operating conditions. It cures between closely fitting metal surfaces to create a powerful bond that prevents component movement, fretting corrosion, and wear.
\n
Designed for use on shafts, bearings, bushes, pulleys, gears, couplings, and sleeves, Loctite 638 is particularly suitable where maximum strength and reliability are required.
