Retaining Solutions

 

Retaining compounds reliably secure bearings, keyways and cylindrical parts into housings or onto shafts. LOCTITE® retaining compounds offer an effective and economical method to eliminate challenges such as loosening, corrosion, backlash and wearing by providing uniform stress distribution and unitizing the assembly.

 

100% unitized assembly

By filling all airgaps, the adhesive distributes load and stress evenly over the joint.

1,000's hours reduced

In unplanned downtime through eliminating cylindrical failure.

Leading to improved machine reliability.

Press Fit Bearings Fail. We Seal.

Gaps exists in traditional cylindrical assembly methods such as press fits and shrink fits. LOCTITE Retaining Compounds work to fill these gaps. Not only do LOCTITE Retaining Compounds significantly increase the reliability of your assemblies, but they also reduce machining and rework costs. LOCTITE Retaining Compounds unitize assemblies against vibrations and provides greater reliability.

Explore Retaining Compounds

LOCTITE retaining compounds are available in many different compositions and strengths to cater to a wide range of industrial applications. These different retaining compounds cover a wide variety of tolerances and applications for plant maintenance and assembly needs. 

A Simple Air Gap Causes Mechanical Fitting Methods to Fail

Failure of cylindrical assemblies can lead to major unplanned downtime and decreased product reliability. Many traditional retaining methods have shortcomings that lead to their failure. Pins & keyway assemblies have an uneven distribution of mass, an imbalance that can lead to vibration at high speeds. Splines and serrations cause high stresses due to the “notch effect”. Press and shrink fits rely on friction alone to transmit torque, requiring close tolerances. Most of these traditional methods involve high production costs.

LOCTITE Retaining Compounds Are The Answer

LOCTITE retaining compounds offer a reliable and cost-effective method to secure bearings, bushes, and cylindrical parts into housings or onto shafts. Because LOCTITE Retaining Compounds are applied as liquid, they fill the entire space between two close-fitting cylindrical surfaces and harden into a tough thermoset plastic, resulting in a unitized assembly. LOCTITE Retaining Compounds increase the maximum load transmission capability of the assembly and eliminate fretting corrosion and expensive machining.
