Q: What is Loctite 641 Retaining Compound used for?

It's designed for retaining bearings and cylindrical parts that need to stay in service reliably but be removed again for periodic maintenance — a medium-strength retaining compound rather than a permanent one.

It provides 12 N/mm² shear strength on steel, fixtures in 20 minutes, fills gaps up to 0.15mm, and has a service temperature range of -55°C to +150°C.

Q: Does Loctite 641 resist shock and vibration in service?

Yes — it's formulated to resist loosening from shock and vibration reliably across the full service life of the joint, while still allowing hand-tool disassembly when maintenance is due.

Product Highlights −

LOCTITE 641 is a medium-strength anaerobic retaining compound for retention of bearings on shafts and in housings where regular dismantling is required. Cures when confined in the absence of air between close-fitting metal surfaces, preventing loosening and leakage due to shock and vibration. Shear strength, steel: 12.0 N/mm2 (1700 psi). Fixture time: 20 min. Gap fill: 0.15 mm. Viscosity: 600 mPa·s. Operating temperature: -55 to +150°C. Colour: Yellow.

Medium strength (12 N/mm2), disassembleable bearing retaining compound for regular maintenance.
Gap fill 0.15 mm, fixture in 20 minutes, -55 to +150°C service range.
Resists vibration and shock on steel bearings, shafts and housing bores.

Loctite 641 is the go-to where bearings, gears or cylindrical parts need to be retained reliably but also removed periodically. Its medium strength holds firm in service while remaining serviceable with standard tooling.
