LOCTITE 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.

LOCTITE retaining compounds fill the inner space between components and cure to form a strong precision assembly.

LOCTITE retaining compounds are much superior to conventional assembly methods

Pins, key/keyway assemblies; Have an uneven distribution of mass and an imbalance that can lead to vibration at high speeds.

Splines and serrations: They cause high stresses due to the “notch effect” that occurs in the area of a key. High machining costs.

Clamp rings, press fits, shrink fits, and taper fits: They rely on friction alone to transmit torque, therefore they are limited by material, surfaces and design. Close tolerances are needed to obtain specific load capacities, leading to high production costs. Interference fitting creates stresses in the components that can lead to failure, particularly when combined with operational stresses.

Welding and soldering: Only compatible metals can be joined, the parts can be distorted by the high temperatures required. Heating of the material can lead to residual stresses and structural degradation. Disassembly can also be difficult or impossible.

Advantages

High-strength products can carry high loads

Fill all voids to prevent corrosion and fretting

100% contact – load and stress is distributed evenly over the joint

Higher load transmission and performance with existing design and geometry solutions

Equal performance with lower interference/lighter construction Advanta
