Rod Seals Manufacturers

The rod seal is often the significant factor for the function of the hydraulic cylinder in its entirety. It is typically the most decisive seal on any type of equipment because a leak in a rod seal can not only decrease the efficiency of the equipment, it also can potentially cause environmental issues. It utilizes a nonsymmetrical design in which the diameter of the seal is oversized for the groove diameter. Oversizing creates a hoop pressure resulting in higher static sealing force on the seal in the gland, which aids in stability and helps to limit the rocking motion of the seal as the rod cycles, which in turn can reduce fluid seepage.
