A load sensing bearing assembly (10) comprises an inner race (12), an outer race (16), and a plurality of rolling elements (24). A cavity (20) is formed behind a raceway (14, 18) of one of the races, and a strain gage (22) is installed in the cavity to measure forces applied to the bearing assembly. A stop (30) is formed inside the cavity with an end (34) of the stop designed not to engage a support structure (S) of the bearing assembly under normal bearing load conditions. The stop engages the support structure when an applied load on the bearing assembly exceeds a predetermined load to prevent excessive flexing of the assembly, such that the strain gage may continue to provide accurate measurements of the load on the bearing assembly after the overload condition ends. |
