► Bare-Co | Retaining Compounds

Precision Locking Solutions for Eliminating Mechanical Looseness & Extending Industrial Assembly Life

Mechanical failure rarely begins with a dramatic break — it usually starts with microscopic movement between fitted components that gradually escalates into tolerance loss, vibration damage & eventual system breakdown.

Bare-Co retaining compounds are high-strength anaerobic adhesives designed to secure metal-on-metal assemblies such as bearings, shafts, housings & cylindrical fits where mechanical fastening alone cannot maintain stability.

Once applied, they cure in the absence of air to form a rigid polymer layer that fills microscopic surface gaps, eliminating movement, reducing wear progression & stabilising load transfer across mechanical interfaces.

In Australian industrial environments where vibration, thermal cycling & continuous duty operation are constant, these compounds act as a critical defence layer against hidden mechanical degradation.

Why Choose Bare-Co Retaining Compounds?

When machinery begins to loosen internally, the damage is often already in progress long before visible symptoms appear.

Bare-Co compounds are engineered to arrest this failure progression by chemically bonding fitted components into a single load-bearing unit, reducing micro-movement under stress.

They deliver:

► Elimination of micro-slippage in press-fit assemblies under load cycling
► Improved torque transfer stability across rotating mechanical systems
► Resistance to fretting corrosion caused by vibration-induced movement
► Enhanced thermal stability in high-heat industrial environments
► Stronger long-term retention of bearings, shafts & housings
► Reduced premature wear in high-vibration machinery applications

When integrated with Bearings, they significantly extend service intervals by stabilising fit integrity at the microscopic level.

Common Applications

Bearing Retention & Housing Stabilisation

In rotating machinery, even minimal clearance expansion can lead to catastrophic alignment failure over time.

► Bearing fixation in worn or re-machined housings
► Prevention of race movement under continuous load
► Restoration of tolerance loss in aged assemblies
► Stabilisation of high-speed rotating equipment interfaces

Shaft Fit Reinforcement & Torque Transfer Systems

Shaft micro-movement is a silent contributor to long-term drivetrain inefficiency.

► Securing slip-fit shafts under fluctuating torque conditions
► Eliminating backlash in rotating drive assemblies
► Reinforcing worn keyless shaft connections
► Improving load consistency across mechanical drive systems

Mining & High-Vibration Equipment Environments

Continuous shock loading accelerates mechanical loosening faster than standard wear processes.

► Crusher assembly retention under constant impact vibration
► Conveyor drive stabilisation in abrasive environments
► Heavy plant repair where tolerances have degraded in service
► Field repair of high-load rotating machinery components

Agricultural & Seasonal Machinery Operation

Extended operating cycles amplify small mechanical inconsistencies into seasonal breakdown risks.

► Tractor drivetrain component stabilisation during field loading
► Harvester bearing security across long duty cycles
► Pump system reinforcement in irrigation equipment
► Agricultural gearbox housing retention under variable load

For preventative surface preparation workflows, technicians often align with Tool Maintenance Kit to ensure correct bonding conditions before application.

Expert Tips

► Ensure all mating surfaces are completely free from oil, grease & contamination before application
► Use correct primer where required to improve bond strength in low-energy surfaces
► Avoid movement during curing phase to achieve full structural bond formation
► Select compound strength based on whether future disassembly is required
► Do not rely on retaining compounds as a substitute for severely damaged mechanical fits
► Align installation procedures with Drive Accessories & Maintenance for full system reliability

Most retaining compound failures occur due to poor surface preparation rather than product selection issues.
