Industries Where Retaining Adhesives Can be Use

Ensures secure fastening in machinery operating under continuous stress.
WHY
Retaining Adhesive?
Retaining Compounds secure bearings, bushes and cylindrical parts into housings or onto shafts. They achieve maximum load transmission capability and uniform stress distribution and eliminate fretting corrosion. Applied as a liquid, they form a 100% contact between mating metal surfaces, eliminating the need for expensive replacement parts, time consuming machining or the use of mechanical methods.
Advantages of Fasto Retaining Adhesive
- High-strength products can carry high loads
- Fill all voids to prevent corrosion and fretting
- 100% contact – load and stress are distributed evenly over the joint
FAQs
What is a Retaining Adhesive?
A retaining adhesive is an anaerobic bonding compound designed to secure cylindrical metal assemblies such as bearings, bushings, sleeves, gears, pulleys, and shafts. It fills microscopic gaps between mating parts and cures in the absence of air to create a strong, durable bond.
What are Retaining Adhesives Used for?
Retaining adhesives are used to secure cylindrical components in industrial assemblies, including:Bearings,
Bushings,
Sleeves,
Shafts,
Gears,
Pulleys,
Rotors,
Couplings, etc,.They help improve load distribution, reduce movement, and increase assembly reliability.
How Does a Retaining Adhesive Work?
Retaining adhesives cure when confined between metal surfaces and deprived of oxygen. Once cured, they create a high-strength bond that prevents relative movement between cylindrical components and helps distribute stresses evenly across the assembly.
What is the Difference Between a Retaining Adhesive and a Thread Locker?
Retaining adhesives are designed for cylindrical assemblies such as shafts and bearings, while thread lockers are specifically formulated to secure threaded fasteners like bolts, nuts, and screws against loosening.
Can Retaining Adhesives Replace Press Fits and Mechanical Fastening Methods?
In many applications, retaining adhesives can enhance or replace traditional mechanical retention methods such as press fits, interference fits, keys, splines, and set screws. They improve load-bearing capacity while reducing wear and fretting.
What Materials Can Retaining Adhesives be used on?
Retaining adhesives are commonly used on:Steel,
