Opis produktu
LOCTITE 641 10 ml — retaining compound for bearings requiring subsequent disassembly
LOCTITE 641 is a one-part anaerobic retaining compound for bonding cylindrical metal components. It is suitable for securing bearings onto shafts and into housings, particularly where periodic disassembly is required for inspections or repairs.
Sold individually. The displayed price is for 1 bottle containing 10 ml.
Applications and properties
The adhesive cures when confined in the absence of air between close-fitting metal surfaces. It helps prevent assemblies from loosening due to vibration and shock loads. Its medium strength facilitates subsequent maintenance.
- Securing bearings onto shafts and into housing bores.
- Bonding close-fitting cylindrical metal components.
- Assembling parts that require periodic disassembly.

Directions for use
- Clean and degrease the mating surfaces, then allow them to dry.
- For slip-fitted assemblies, apply the adhesive to the shaft and the inside of the collar. Assemble the parts using a rotating motion.
- For press-fitted assemblies, apply the adhesive to both mating surfaces and assemble promptly.
- Allow the assembly to cure. Fixture time does not indicate that full strength has been achieved.
Cure speed depends on the type of metal, gap size and temperature. Read the label and the current Safety Data Sheet before use.
Frequently asked questions
Do I have to buy 12 pieces?
No. The product is sold individually. One piece means one bottle containing 10 ml of adhesive.
Can the assembly be dismantled later?
Yes. The medium strength of LOCTITE 641 facilitates disassembly during servicing. The disassembly method should be selected according to the assembly design and the manufacturer's recommendations.
Can the assembly be fully loaded after 20 minutes?
Fixture time should not be confused with full cure. Before applying loads, take into account the material, gap size and assembly temperature.
Is the adhesive suitable for plastics?
The product is primarily intended for metal assemblies. Henkel does not generally recommend its use on plastics, particularly those susceptible to stress cracking.
