Self Adjustment and Aligning

rotary shaft seals

CinchSeal rotary shaft seals readily accommodate a reasonable amount of shaft vibration, misalignment, or wobble. The rotor cup “floats” against the face of the stator plate so any lateral shaft movement produces nothing more than a slight orbital eccentricity.
