High load retention with Loctite 638
- Reliable cylindrical parts assembly: You secure sleeves, gears, and pulleys against heavy dynamic loads and severe vibrations.
- Effective gap filling performance: You bridge diametral clearances up to 0.25 mm for a rigid structural bond.
- Strong resistance to heat: You maintain dependable joint strength in operating temperatures from -55 °C to 180 °C.
With Loctite 638 retaining compound, you secure cylindrical metal parts firmly against severe vibrations and heavy dynamic loads. Supplied in a 50 ml bottle, this anaerobic retaining adhesive bridges diametral clearances up to 0.25 mm and provides uniform stress distribution across shafts, bearings, bushings, and gears. Thanks to its good oil tolerance, the liquid cures reliably even through minor surface contamination. You also gain dependable joint strength across an operating temperature range of -55 °C to 180 °C, eliminating costly high-tolerance machining and preventing premature wear during maintenance.
Product description:
- LOCTITE 638 - Retaining Compound - Henkel
- LOCTITE 638 is designed for the bonding of cylindrical fitting parts, particularly where bond gaps can approach 0.25 mm.
- The product cures when confined in the absence of air between close-fitting metal surfaces and prevents looseningand leakage due to shock and vibration.
- It not only works on active metals but also on passive substrates, exhibiting robust cure performance.
- The product offers high-temperature performanceand good oil tolerance, and tolerates minor surface contaminants.
