Retaining products have a high load-bearing capacity – with LOCTITE you can find the right product for cylindrical parts. Find out more here!
Our Retaining Products
LOCTITE retaining products secure bearings, bushes and cylindrical parts into housings or onto shafts. They increase maximum load transmission capability and uniform stress distribution and eliminate fretting corrosion. Applied as a liquid, they allow 100% contact between mating metal surfaces, eliminating the need for more expensive designs, time consuming machining and even the use of mechanical methods.

Advantages of LOCTITE Retaining Compared to Conventional Assembly Methods
- Higher strength with simplified and less costly designs
- Reduces dependence on machining tolerances
- Prevents corrosion and fretting
- Load and stress is distributed evenly over the Joint
When Used in Combination With Interference Fits, LOCTITE Retaining Compounds Allow:
- Higher load transmission and better performance with existing designs and geometry.
- Equal performance with relaxed tolerances.
- Reductions in the size and weight of an assembly.
Problems With Conventional Assembly Methods that LOCTITE Retaining Products Can Help Overcome
Pins, key/keyway assemblies have 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” that occurs in the area of a key. And they have high machining costs.
Clamp rings, press fits, shrink fits, and taper fits 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.
