HBYR Rod Seal – Heavy-duty double-acting rod seal with dual anti-extrusion backup rings. Symmetrical/stepped lip arrangement delivers reliable sealing in both high-pressure and alternating-pressure applications. Twin backup rings provide superior gap extrusion resistance under extreme pressure spikes and side loads. Optimized contact geometry reduces friction and operating temperatures. Rugged construction ensures outstanding durability in mining, construction, and heavy-equipment hydraulics. Material: high-modulus polyurethane with engineered backup rings. Temp: –40°C to +110°C. Pressure: up to 50 MPa.
