These B620 and B648 retainers are high-strength anaerobic compounds designed for securing cylindrical components, offering enhanced performance under high temperatures and dynamic conditions. B620 is specifically formulated to withstand temperatures up to 200°C, making it ideal for automotive, aerospace, and industrial equipment like engines and turbines. B648 is suited for bonding gears, rotors, and shafts in similar environments, where reliable performance under shock and vibration is critical.

Features and Benefits
• High-temperature resistance, ideal for environments exposed to high heat
• Enhance the reliability of mechanical assemblies by ensuring secure fits even under harsh conditions
• Eliminates backlash in keys and splines preventing mechanical play and wear in critical component interfaces
• Strengthens heavy press fits enhancing the fit and load capacity of assembled parts
• Fretting corrosion prevention protects the metal surfaces from the microscopic wear and oxidation that occurs in tight fits
• Environmental corrosion sealing offers a barrier against damaging environmental elements
• Designed to minimise the risk of damage from uneven stress distribution during operation
• Formulated to maintain uniform force distribution, critical for mechanical efficiency and longevity
