HBYR Rod Seal – Heavy-duty double-acting rod seal with Y-ring lip geometry and dual anti-extrusion backup rings. Asymmetric lip configuration ensures reliable bidirectional sealing under extreme pressure peaks and alternating pressure conditions. Twin backup rings provide superior gap extrusion resistance and stable groove retention under severe side loads and shock forces. Optimized lip contour minimizes friction, operating temperatures, and stick-slip. Rugged elastomeric construction delivers outstanding durability in mining, construction, heavy equipment, and off-highway hydraulics. Material: high-modulus polyurethane with engineered backup rings. Temp: –40°C to +110°C. Pressure: up to 50 MPa. Speed: up to 2 m/s.
