Cómo seleccionar el compuesto de retención adecuado

What is a Retaining Compound?

A retaining compound is an anaerobic adhesive whose primary function is to securely bond bearings, bushes, and other cylindrical parts into housings or on shafts. Often referred to specifically as a bearing retaining compound when used in these applications, this type of adhesive cures with the absence of air and the presence of an active metal. Retaining compounds have a broad range of industrial applications, finding uses wherever joined components require high-strength bonding and sealing solutions.

FAQs about Loctite retaining compound

Which Loctite retaining compound is the strongest?

The strongest Loctite retaining compound available for general purpose industrial applications is typically Loctite 638. It offers high strength for dynamic loads and large gaps.

How long does it take for a Loctite retaining compound to cure?

Loctite retaining compounds typically achieve fixture strength in 10-30 minutes, meaning the assembly can be handled. A full cure and maximum strength are usually reached within 24 hours. Cure time can vary based on the specific product, temperature, and gap size.

Can a threadlocker be used as a retaining compound?

While both are anaerobic adhesives, threadlockers are for threaded fasteners, optimised for small, consistent gaps. Retaining compounds are for larger, varying cylindrical gaps in non-threaded parts, offering higher strength and gap-filling capabilities. Using a threadlocker as a retaining compound is generally not recommended for critical applications, as it can lead to insufficient bond strength and premature failure. Always choose a dedicated retaining compound for cylindrical assemblies.

How do I choose the right Loctite retaining compound?

Selection depends on gap size, strength needs, and temperature range. For example:

  • Small gaps (≤0.15mm): Loctite 603
  • Medium gaps (0.15–0.25mm): Loctite 638
  • High-temperature use (up to 230°C): Loctite 640
