Пылезащитное уплотнение втулки гидроцилиндра стрелы Caterpillar 1931381

The Boom Cylinder Bushing Dust Seal forms a protective barrier around the bushing to stop contaminants from entering the joint. It prevents dust, dirt, and other particles from reaching the moving surfaces inside the assembly. Maintaining cleaner contact surfaces reduces abrasive wear and allows the bushing to operate smoothly. The dust seal also helps retain lubrication inside the interface, which supports consistent movement during repeated hydraulic cycles.Attributes:• Reduces friction caused by external contaminants.• Limits external particle contact with the bushing.• Helps retain lubrication within the joint.Applications: The Boom Cylinder Bushing Dust Seal is fitted in the rod eye to enclose the bushing and protect it from contaminants during boom cylinder operation.
