A comprehensive engineers' reference source for radial ball bearings and thrust ball bearing



Most adhesives used for metal-to-metal bonding are of the anaerobic type. These adhesives require the absence of oxygen before curing can start. At least one mating surface must be porous to oxygen in order to allow absorption of oxygen from the bond. This type of adhesive can have shear strength in the order of 2-5,000 pounds per square inch, resulting in push-out forces of hundreds of pounds, even for a small assembly.

There are many types of suitable anaerobic adhesives available from several manufacturers. The specific adhesive used will depend on the materials to be bonded and the application itself. Dynaroll has extensive adhesive bonding experience and our bearing engineers can make adhesive recommendations based on each application. Please contact Dynaroll for the latest information on adhesives.
