HBYR Seal – Extreme-Pressure Rod Seal with Twin Anti-Extrusion Protection

HBYR Rod Seal – Heavy-Duty Double-Acting Hydraulic Rod Seal with Y-Ring and Dual Backup Rings.

Heavy-duty HBYR rod seal with Y-ring geometry and dual backup rings for extreme-pressure hydraulic cylinders. Anti-extrusion, low-friction, PU. –40°C~110°C, ≤50 MPa.

HBYR Rod Seal – A rugged heavy-duty hydraulic rod seal engineered for extreme-pressure and high-cycle double-acting cylinder applications. This Y-ring rod seal features a dual anti-extrusion backup ring configuration that provides superior gap resistance under severe pressure spikes, shock loads, and side forces. The asymmetric lip profile ensures reliable bidirectional sealing in both dynamic and static conditions, while the high-modulus polyurethane compound delivers outstanding abrasion resistance and thermal stability. The twin-ring protection system prevents extrusion into radial clearances, maintaining seal integrity even under alternating pressure conditions. This heavy-duty sealing solution is ideal for mining equipment, construction machinery, off-highway vehicles, and heavy industrial 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.
