Пылезащитный уплотнитель штока гидравлического цилиндра Caterpillar 6Q9221

The Hydraulic Cylinder Rod Dust Seal, also known as a wiper seal, is used to prevent external debris from entering the hydraulic cylinder as the rod retracts. It plays a role in extending the service life of internal components by acting as the first line of defense against environmental contamination. These seals are made from tough elastomeric or polyurethane materials that are resistant to abrasion, UV exposure, and harsh temperatures. Attributes:• Suitable for a diameter rod of 55 millimeters.• Protects internal seals and hydraulic fluid.• Maintains overall cleanliness of the hydraulic cylinder.Applications: The Hydraulic Cylinder Rod Dust Seal is located at the outermost edge of the cylinder’s rod end, where the dust seal scrapes off accumulated grime and prevents it from bypassing into the seal gland. They work in tandem with the rod seal to ensure both contamination control and leak prevention.
