Three new Loctite^®anaerobic retaining compounds can allow primerless performance on oily or contaminated surfaces, even at operating temperatures as high as 180°C. Used in combination with interference fits to secure bearings, bushings, gears and cylindrical assemblies into housings or shafts, Loctite 638™, 648™ and 680™ retaining compounds reportedly allow: higher load transmission; better performance with existing designs; relaxed machining tolerances; and reductions in the size, weight and overall cost of an assembly.

All three retaining adhesives can reportedly make joints stronger, distribute stress evenly, prevent corrosion and fretting, and reduce or eliminate expensive machining and surface-finishing operations.
