UDI Rod Seal – Heavy-Duty Double-Acting Hydraulic Rod Seal with Integrated Anti-Extrusion Backup Rings
High-performance UDI rod seal for heavy-duty hydraulic cylinders. Double-acting, low-friction, with integrated anti-extrusion backup rings. PU, –35°C~110°C, ≤40 MPa.
UDI Rod Seal – A high-performance hydraulic rod seal engineered for demanding double-acting cylinder applications. This heavy-duty rod seal features a one-piece cartridge design with integrated anti-extrusion backup rings that resist gap extrusion under high-pressure spikes and cyclic loading. The asymmetric lip profile ensures reliable bidirectional sealing with minimal leakage, while the low-friction polyurethane compound reduces operating temperatures and extends service life. The compact monobloc construction simplifies installation, reduces assembly errors, and fits standard groove profiles — making it an ideal sealing solution for medium to heavy-duty hydraulic cylinders in mobile and industrial equipment. Material: abrasion-resistant polyurethane with integrated support elements. Temp: –35°C to +110°C. Pressure: up to 40 MPa. Speed: up to 2 m/s.
