Automotive Adjustable Adapter Assemblies


Multiple spindles require the accuracy of precision Acme threads and the concentricity of a precisely ground O.D. and I.D. All adapters are produced to precise automotive standards to maintain maximum spindle performance and minimize tool runout. The lock nut provides the positive positioning desired in the spindle.
