DKBI Dust Seals Product Features
Strong wiping action removes dust, mud, metal particles, and contaminants while providing excellent oil-scraping performance.
Made from modified polyurethane (TPU) with an embedded steel frame, offering long service life and superior elasticity.
The primary sealing lip maintains consistent pressure against the rod surface, ensuring reliable hydraulic oil retention.
The secondary dust lip prevents external contaminants from entering the hydraulic system.
Steel inner frame enhances rigidity and ensures a secure interference fit in the mounting groove.
Simple groove design and tight-fit structure allow fast, stable installation.
Applications
Hydraulic cylinder rods
Engineering and construction machinery
Heavy-duty industrial hydraulic equipment
Environments with high contamination and frequent reciprocating motion
