Structural Integration & Sealing Principle
🔧 Product Overview
The YX and YXD series PU hydraulic seals, together with the U‑cup rod seal, are precision‑engineered for demanding machinery applications. Manufactured from high‑grade polyurethane, they deliver exceptional wear resistance and long service life under high‑pressure cycles.
🛡️ Superior Sealing Performance
The unique lip design ensures tight, low‑friction sealing against dynamic rod motion, effectively preventing fluid leakage and contamination ingress. The YXD variant features an added buffer lip for enhanced shock absorption in reciprocating systems.
⚙️ Material Advantages
Premium PU compound offers excellent tensile strength, high tear resistance, and stable performance across a wide temperature range (–35°C to +100°C). It resists hydraulic oils, water‑glycol fluids, and most industrial lubricants without swelling or hardening.
📦 Versatile Compatibility
Available in standard metric and inch sizes, these seals fit most hydraulic cylinders, pumps, and valves. They are easy to install, require minimal break‑in, and maintain consistent friction characteristics even after prolonged standby periods.
✅ Reliable Choice for Industry
Ideal for construction equipment, agricultural machinery, presses, and injection molding machines. Backed by strict quality control, YX/YXD and U‑cup seals reduce downtime, lower maintenance costs, and ensure stable operation in harsh working conditions.
