By comparison with conventional assembly methods, the use of an engineering adhesive to secure bearings, bushes and cylindrical parts into housings or onto shafts has many merits. These retaining compounds provide an effective and economical method of eliminating loosening, backlash, fretting corrosion and wear by unitising the assembly and ensuring uniform stress distribution.
The LOCTITE brand is reported to be pre-eminent in this field. Applied as a liquid, the LOCTITE retaining compound fills all the voids between mating metal surfaces to create 100% contact so load and stress are distributed evenly over the joint. The method eliminates the need for expensive replacements parts, time-consuming machining or the use of mechanical methods such as pins, key/keyway assemblies, splines and serrations, clamp rings and press-, shrink- and taper fits.

HENKEL says when it started to explore the best way to convey the merits of its latest LOCTITE structural bonding development, it set its sights on creating a demonstration that would really make industry take notice. Henkel engineers decided to show the strength and durability of new and patented LOCTITE hybrid adhesive technology by designing a bonded coupler that would pull freight train wagons weighing 208 tons.
