Retaining Adhesives

Anaerobic Retaining Adhesives

Retaining Adhesives for Bearing Mounting, Shaft Assembly & Cylindrical Part Retention

Fasto Retaining Adhesives are high-performance anaerobic bonding compounds designed to secure cylindrical metal assemblies such as bearings, bushings, sleeves, gears, pulleys, rotors, and shafts. Also known as retaining compounds, bearing retaining compounds, or shaft retaining adhesives, these products cure in the absence of air between closely fitted metal surfaces to create a strong and durable bond.

Retaining adhesives are widely used across Industrial Machinery, Transportation, Agricultural Machinery, Automotive Manufacturing, Solar Equipment, LED Equipment, Appliances, and General Engineering industries where reliable cylindrical assembly retention is critical.

Whether you need to secure bearings on shafts, retain bushings within housings, or prevent fretting corrosion in rotating assemblies, Fasto Retaining Adhesives provide dependable performance and long-term reliability.

What Are Retaining Adhesives?

Retaining adhesives are anaerobic compounds specifically formulated to bond and retain cylindrical metal parts. When applied between mating metal components, the adhesive cures to create a high-strength bond that distributes load evenly across the assembly.

Unlike mechanical locking methods such as press fits, keys, splines, and interference fits, retaining compounds fill microscopic gaps between components, improving load distribution and increasing assembly strength.
