Поршневое расширительное кольцо, внутренний диаметр 3,8 дюйма Caterpillar 5J8010

A Piston Expander Ring is positioned on the piston and serves to provide a secure seal between the piston and cylinder bore. The primary function of the expander ring is to prevent fluid leakage and maintain hydraulic pressure within the cylinder, ensuring efficient operation of the bucket unit. It works by exerting outward pressure against the cylinder wall, creating a tight seal. It is made of durable materials to withstand the forces exerted by the operation.Attributes:• Maintain consistent hydraulic pressure for efficient operation• Minimizes internal leakage, optimizing the power transferApplications:A Piston Expander Ring used in a backhoe bucket cylinder helps maintain consistent hydraulic pressure for efficient operation. It minimizes friction between the piston and cylinder, reducing wear.
