Achieve Unyielding Precision and Strength for Bearings and Cylindrical Assemblies with LOCTITE® 638 High Strength Retaining Compound

For critical assemblies demanding robust and permanent bonding of cylindrical fitting parts, including bearings, bushings, shafts, gears, and pulleys, 3FPARTS.COM proudly presents the LOCTITE® 638 High Strength Retaining Compound. This 50 ml, single-component anaerobic adhesive is specifically engineered for high-strength retention in applications with narrow bond gaps up to 0.25 mm (0.01").

LOCTITE® 638 delivers exceptional performance on all metals, including passive substrates such as stainless steel, ensuring a fast and reliable cure. Its advanced formulation provides excellent temperature performance (from -55°C to 180°C / -65°F to 355°F) and superior oil tolerance, allowing it to effectively bond even on surfaces with minor industrial oil contaminants without prior cleaning.

This high-viscosity compound is the ideal solution for permanently securing components like bearings into housings, shafts into rotors, gears onto shafts, and pulleys or similar cylindrical parts. Beyond its primary role as a retaining compound, LOCTITE® 638 can also be effectively utilized for demanding high-strength threadlocking and thread sealing applications, adding to its remarkable versatility.

Reliable Performance, Certified Quality: LOCTITE® 638 is designed to resist loosening and leakage caused by severe shock and vibration. It fills all voids between mating parts, curing into a rigid thermoset polymer that significantly reinforces the joint. This results in up to a 40% increase in breakaway torque, reinforcing the overall joint stability. Furthermore, this product meets the stringent performance requirements of KIWA GASTEC QA AR 214 for admixtures up to and including 100% hydrogen gas on metal threaded fittings, affirming its suitability for emerging energy applications where certified safety is paramount.
