In addition to protecting the cylinder from contaminants, dust seals also help maintain the proper lubrication levels within the system. When dust and dirt particles enter the cylinder, they can mix with the hydraulic fluid and create abrasive sludge. This not only increases friction within the cylinder but also reduces the effectiveness of the lubrication, leading to increased wear on the moving parts. By keeping out contaminants, dust seals help ensure that the hydraulic system operates smoothly and efficiently.
