Balancing Machines, Dynamic, Ball Type Slave Bearings for Rotor Support
This Aerospace Recommenced Practice (ARP) defines a series of ball bearings which are specifically designed to support the rotor in a dynamic balancing machine. By establishing certain bearing sizes the number of required balancing machine support adapters will be reduced. The intent is that each size bearing identified by its outside diameter and width will be capable of accommodating any bore diameter within the specified range of that size. This ARP specifies both the nominal dimensions and the tolerances for a series of ball bearings with semifinished inside diameters which are suitable for supporting gas turbine rotating components in dynamic balancing machines.
Rationale: This original standard was based on terminolgy and informatioin available in 1973. The document requires updating and modification to current manufacturing processes, general practices, and terminology to be more current for the industry.
