Description
Heartland FasLok Retaining Compound is an anaerobic retaining adhesive for cylindrical metal assemblies that need locking between close-fitting parts. Use it on bearings, bushings, sleeves, gears, pulleys, and shaft-mounted components when a liquid retaining adhesive can fill small voids and support the mechanical fit.
FasLok Retaining Compound Benefits
- Anaerobic chemistry cures between metal surfaces when air is excluded from the joint.
- Helps lock slip-fit and press-fit cylindrical parts against movement, fretting, and vibration.
- Fills small surface irregularities that can remain after machining, wear, or normal tolerance stack-up.
- Green retaining grades in the Fas-Lok family cover different viscosities, cure speeds, and strength levels.
- Useful for maintenance teams and OEM assembly lines that want a clean liquid alternative to staking or sleeving.
This product family fits metal-to-metal retaining work where the parts are already designed to carry load and the adhesive is used to stabilize the joint. Clean oil, chips, and loose corrosion from the parts before assembly. Apply the compound to the mating area, assemble promptly, and allow the joint to cure before putting the equipment back under load.
Common Applications for Retaining Compounds
- Securing bearings, bushings, and sleeves in housings.
- Retaining gears, pulleys, rotors, and collars on shafts.
- Repairing worn fits when the gap is still within the selected grade range.
- Reducing movement in cylindrical assemblies exposed to vibration.
- General plant maintenance where metal parts need a retained slip fit.
Compatible Materials and Use Notes
- Best suited to active metal surfaces such as steel and iron.
- May require additional surface preparation or primer on inactive metals.
- Works only where adhesive is confined between mating parts, not as an exposed surface coating.
- Grade selection should match gap size, required strength, cure speed, and service temperature.
