The UDI type piston rod seal is a high-performance single-acting hydraulic rod seal designed for reciprocating piston rods in hydraulic cylinders. Featuring a precision asymmetrical sealing lip structure, the UDI rod seal achieves self-sealing pressure energization, which greatly improves sealing tightness as system pressure rises.
Made of high-quality polyurethane material, this UDI piston rod seal has excellent abrasion resistance, tear resistance and low friction characteristics. It effectively stops internal hydraulic fluid leakage and blocks external dirt, dust and moisture from invading the hydraulic cylinder. The built-in anti-extrusion profile enhances stability under high pressure, avoiding seal deformation and extrusion damage during long-time reciprocating movement. It can work steadily under pressure up to 32 MPa, with operating temperature ranging from -35℃ to 100℃.
Compatible with mineral hydraulic oil and many synthetic hydraulic media, UDI piston rod seals are widely used in excavators, forklifts, injection molding machines and various industrial hydraulic equipment. It conforms to standard seal groove sizes for quick installation and direct replacement. Reducing oil leakage failures and lowering maintenance frequency, the UDI hydraulic rod seal offers a reliable and economical sealing solution for heavy-duty hydraulic systems.
