Wiper 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 Lips
Function: 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 Boots
Function: Flexible covers shielding entire rod assemblies. Ideal for extreme contamination or corrosive environments.
Material: Typically elastomers or reinforced fabrics.
Labyrinth Seals
Function: Non-contact design using grooves to trap particles via centrifugal force. Low friction, suitable for high-speed applications.
Common Materials
Polyurethane (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.
