Description
The IDR-Type Piston Rod Seal (Inverted Double-Ring seal) is a heavy-duty, two-component hydraulic sealing system engineered for extreme-pressure piston rod applications requiring superior extrusion resistance and long-term reliability. Featuring a primary polyurethane sealing ring with a separate backup/anti-extrusion element, the IDR design provides exceptional performance under high-pressure cycling, shock loads, and demanding environmental conditions.
Technical Summary: The IDR-Type piston rod seal is a heavy-duty, two-component sealing system engineered for extreme-pressure hydraulic applications up to 60 MPa (600 bar). The primary polyurethane sealing ring provides self-energized pressure sealing and contamination wiping, while the secondary POM/PTFE/PA backup ring provides superior anti-extrusion protection. Ideal for heavy mobile equipment, industrial presses, ultra-high pressure systems, and applications with severe pressure spikes or shock loads.
