The URUA rod seal ring is a main rod seal ring made of polyurethane rubber by turning molding process. This processing form has the characteristics of mold, fast, flexible size, and can provide customers with the products they need more quickly. Because the sealing ring used for ordinary polyurethane rod is of the same material, the performance surface is completely equivalent to that of URU series.

URU rod seal ring is the main rod seal ring made of polyurethane rubber. This is a form of design that has been tested for a long time. Because of its good mechanical properties, it is widely used in the use of standard cylinders. It is especially suitable for the field of construction machinery in harsh environment. The asymmetrical lip design ensures optimal resistance to dynamic pressure in reciprocating motion. At low speeds, crawling may occur because of insufficient oil film formation. The notch on the back of the lip eliminates pressure accumulation between the sealing rings.
