Product Information

R41 Retainer

Lockfast R41 Bearing Retainer


Lockfast R41 Bearing Retainer is a yellow, medium-strength, medium-viscosity retaining compound used for bonding cylindrical fitting parts where disassembly is required in the future.  Typical applications include the mounting/retention of bearings and bushes onto shafts and into housings. R41 can also prevent loosening and leakage from shock and vibration.  UV fluorescent properties allow the products presence to be monitored in quality control via a UV black light.


Directions For Use


1. For optimum performance surfaces should be clean and free of grease.

2. If the material is an inactive metal consider using activator.

3. Shake the product thoroughly before use. Apply several drops to parts to be bonded.

4. Assemble as required. (see the Lockfast retainer technical information sheet for further information on types of application).

5. To prevent the clogging of the nozzle, do not let the tip touch metal surface during application.


Fixture Time vs. Substrate


There may be a difference in fixture speed and strength based on the substrate. As opposed to passive materials such as stainless steel or zinc dichromate, anaerobic adhesives will reach full strength more rapidly with active materials such as mild steel and brass.

For more information on strength of bond and cure time, please see the Lockfast retainer technical information sheet.


Disassembly and Clean-up


Remove with standard hand tools. In circumstances where hand tools do not work, use localised heat, disassemble while hot. To remove cured product use a combination of solvent and abrasion such as a wire brush.
