Breakaway Force of a Magnet

This document explains the test methods used to determine how much force it takes to pull a magnet directly away from the surface it is attached to.

Effect of Surface Thickness on Holding Strength

This chart explains the relationship between the thicknesses of the surface an assembly is attached to, and the amount of weight the assembly can hold. We used our popular item RB-80 (64H0004) in this example. If you need to know how surface thickness affects a different Adams assembly, please contact us and we'll get you the answers you need.

Effect of an Air Gap on Holding Strength

This chart explains the effect of an air gap on the amount of weight an assembly can hold. We used our popular item RB-80 (64H0004) in this example. If you need to know air gap effects for a different Adams assembly, please contact us and we’ll get you the answers you need.
