Inspection Procedures: Limitations – Dish, Pitch & Burr

Limitations—Dish, Pitch & Burr

Rotor Clip retaining rings meet accepted industry parameters for limitations of dish and pitch. These characteristics are illustrated below.

DISH LIMITATIONS
Dish is any difference in height occurring from the outer edge of the ring to the inner edge. This condition should be considered separate from Pitch (see below). To determine Dish, a small amount of weight can be applied to the upper surface of the ring to remove pitch from the overall height measurement.

     

 
 
PITCH LIMITATIONS
Pitch takes into account thickness of the ring including any mismatching of lugs, where applicable.

   

 
 
BURR LIMITATIONS
A burr results from the metal stamping process. It is a raised edge for which the following parameters apply.
