An agitator is a device or mechanism used to put something into motion by shaking or stirring. In general, agitators usually consist of an impeller and a shaft. An impeller is a rotor located within a tube or conduit attached to the shaft. Agitators are used to mix liquids or products together or to prevent congealing. Collars can be found in all types of restaurant equipment and are common accessories to other components. A collar is a restraining or connecting band, ring, flange, or pipe in machinery used to restrain motion, hold something in place, or join two or more parts together. Mechanical collars often hold bearings and sprockets on shafts, situate components in motor and gearbox assemblies, and serve as mechanical stops. Collars may also be used on cups and containers, blending pitchers and more. Features. 0.65 x 2.65 x 0.65 Agitator Collar. Made with high quality materialSpecifications. Length 0.65. Width 2.65.
