duo cone seal

Floating Seal also known as duo cone seal or mechanical face seal, floating seal is an essential sealing part for final drives and wheel assemblies of excavators, bulldozers and other construction machinery. It consists of high-hardness alloy cast iron seal rings and elastomer O-rings in NBR, HNBR or FKM, available in DO and DF types. With precision lapped sealing surface, it features outstanding wear resistance, temperature resistance and anti-fouling performance. Adopting advanced floating compensation design, our products automatically offset shaft eccentricity and runout. The uniform oil film formed during operation delivers excellent self-cleaning effect and maintenance-free service. It works steadily at -40℃ to 200℃ with max working pressure up to 3MPa, and the service life exceeds 8000 hours under standard conditions. As a core product of WONEPART, our floating seals and full-range machinery parts have been widely used in major projects including Lusail Stadium for Qatar World Cup, performing reliably under high temperature and sandy conditions. We offer 18-month warranty and global after-sales service, providing trustworthy sealing solutions for heavy-duty equipment worldwide.
