Misalignment

IntroductionSelection Guide Engineering DataBrochure

Radial deep groove ball bearings do have the ability to accomodate a limited amount of angular misalignment. The amount of angular misalignment that can be tolerated before adversely effecting bearing performance is a function of a variety of parameters. Internal radial clearance, internal design, applied loads, and the size of the bearing all play a role in determining the bearing's misalignment capability. Because of this, exact values for allowable misalignment are not provided. Under normal operating conditions,a safe estimate of permissable angular misalignment is usually between .0005 in/in and .003 in/in. Noise levels may increase when the bearing is operating misaligned.
