Product Description Types of Hydraulic Dust SealsWiper Seals (Scraper Seals)Function: Primary defense against external contaminants (dust, dirt, moisture). Installed on the rod side of cylinders to scrape debris during retraction.Design: Rigid lips with sharp edges for effective particle removal. Often paired with secondary seals for redundancy.Rod Seals with Integrated Dust LipsFunction: Dual-purpose seals combining fluid retention and dust exclusion. The outer lip acts as a wiper, while the inner lip retains hydraulic fluid.Applications: Compact systems requiring space efficiency.Bellows and BootsFunction: Flexible covers shielding entire rod assemblies. Ideal for extreme contamination or corrosive environments.Material: Typically elastomers or reinforced fabrics.Labyrinth SealsFunction: Non-contact design using grooves to trap particles via centrifugal force. Low friction, suitable for high-speed applications.Common MaterialsPolyurethane (PU)Advantages: Excellent abrasion resistance, durability, and load-bearing capacity. Performs well in moderate temperatures (-30°C to +80°C).Use Cases: Wiper seals in construction/agricultural machinery.Nitrile Rubber (NBR)Advantages: Cost-effective, good oil/fuel resistance. Limited temperature range (-40°C to +120°C).Limitations: Poor performance in ozone or extreme heat.Fluorocarbon Rubber (FKM)Advantages: Superior chemical/thermal resistance (-20°C to +200°C). Ideal for aggressive environments.Applications: Aerospace, chemical processing.Polytetrafluoroethylene (PTFE)Advantages: Low friction, wide temperature tolerance (-100°C to +260°C), and chemical inertness. Often combined with elastomers for elasticity.Use Cases: High-pressure systems with dynamic motion.Thermoplastic Polyester (TPE)Advantages: Balanced elasticity and wear resistance. Resistant to cracking under dynamic stress.
