To withstand demanding hydraulic environments, CFKS produces GA seals in specialized elastomer Formulations, primarily NBR and FKM. Standard NBR formulations deliver excellent tensile strength and superior resistance to mineral-based hydraulic oils, grease, and abrasion across operating temperatures from -20℃ to 120℃. For high-temperature applications, high-velocity shafts, or synthetic fluids, our premium FKM elastomers extend performance up to 220℃ while providing exceptional chemical immunity against aggressive additives and high-thermal oxidation. The elastomeric compound is bond-engineered directly to the steel casing to prevent inter-layer delamination during long-term service.

Achieving optimal seal life requires proper alignment during installation to avoid dynamic lip distortion. The GA double-lip profile allows for straightforward press-fitting into open housings using standard hydraulic press tooling or uniform driver sleeves without requiring full shaft teardown in routine maintenance cycles. The balanced contact pressure geometry lowers overall dynamic friction, reducing shaft heat buildup and preventing premature grooving on hardened journal surfaces. This low-friction characteristic significantly extends continuous operational service intervals in high-duty excavators and heavy industrial hydraulic equipment.
