HBYR Rod Seal – One-Piece Heavy-Duty Hydraulic Rod Seal with Y-Ring and Integrated Backup Rings for Extreme-Pressure Cylinders.
HBYR one-piece heavy-duty rod seal with Y-ring and integrated backup rings for extreme-pressure hydraulics. Bidirectional, anti-extrusion, durable. PU, –40°C~110°C, ≤50 MPa.
HBYR Rod Seal – A rugged one-piece heavy-duty hydraulic rod seal engineered for extreme-pressure, high-cycle double-acting cylinder applications. This heavy-duty rod seal integrates a Y-ring lip geometry with multiple anti-extrusion backup rings in a monobloc design, providing superior bidirectional sealing and gap resistance under severe pressure spikes, shock loads, and side forces. The pressure-energized lip design ensures tighter sealing as system pressure increases, while the integrated backup rings prevent extrusion into radial clearances. The optimized lip contour minimizes friction, heat generation, and stick-slip for extended service life. The one-piece cartridge construction simplifies installation, eliminates assembly errors, and ensures reliable performance in the harshest environments. This heavy-duty sealing solution is ideal for mining equipment, construction machinery, off-highway vehicles, and heavy industrial hydraulics. Material: high-modulus polyurethane with integrated backup rings. Temp: –40°C to +110°C. Pressure: up to 50 MPa. Speed: up to 2 m/s.
