1.Segmented shaft Seal Ring consists of certain number of segments surrounded by spring. Number of segments depends on shaft diameter.

2.During the application medium pressure is equally distributed on outer ring diameter, the purpose of spring is to hold segments together until sufficient pressure of medium is achieved. Number of segment rings depends on working pressure.

3.For assembly reasons the carbon rings are made in segments and are held in position in housings and anti-rotation pin is fitted to each ring to prevent it rotating with the shaft.

4.Either rectangular section rings or bevel section rings may be used. The segments are usually butt- jointed.
