Product Description

Hydraulic Cylinder Shaft Polyurethane PU Dust Wiper Oil Seal
Product Description

DH/DHS Hydraulic Cylinder Shaft PU Dust Wiper Oil Seal | High-Temperature Resistance Industrial Scraper Seal for Hydraulic Systems
DH/DHS is double wiper for improving the overall sealing effect; dimensions for standardized installation spaces as per ISO 6195 Type C. Its lip seal with molded-on wiper lip (double-lip wiper); sealing edge of wiper lip slightly rounded.
Product Advantages 
1. Inwardly directed sealing lips provide the function of a lip seal 
2. Wiper lip with a slightly rounded sealing edge can be relied upon to strip off dirt, and leaves a residual film of oil on the entering rod, with concomitant  benefits for the sealing effect, the lifetime and the friction behavior.

DH/DHS Hydraulic Cylinder Shaft PU Dust Wiper Oil Seal
Premium polyurethane (PU) dust wiper oil seals designed for DH/DHS hydraulic cylinder shafts, providing superior protection against contaminants while maintaining reliable sealing performance. Engineered with a dual-lip scraping design, these seals effectively remove dust, dirt, and moisture from the rod surface, preventing abrasion and extending cylinder lifespan.
 
Key Features
 
  • High-Performance PU Material:
    • Durable polyurethane compound with excellent resistance to oil, fuel, and chemicals
    • Operates in temperatures ranging from -35°C to +100°C (-31°F to +212°F)
    • Shore hardness: 80-90 A for optimal balance of elasticity and wear resistance
  • Dual-Lip Scraper Design:
    • Primary lip removes debris from the rod during retraction
    • Secondary lip prevents oil leakage and enhances sealing efficiency
    • Reduces friction and wear in dynamic applications
  • Precision Engineering:
    • CNC-machined to ISO 3601-1 standards for tight dimensional tolerances
    • Available in standard metric sizes (e.g., 98x108x6mm, 100x110x8mm) and imperial equivalents
    • Custom dimensions and profiles available for non-standard applications
