The double acting rotating grid ring is used to seal the rod, shaft, cylinder hole, rotating transmission input end, and rotating joint in rotating, spiral, or swinging motion, and is exerted by the force of the elastic 0-shaped ring. The dual acting performance of the seal comes from the symmetrical cross-sectional structure, which allows the seal to withstand bidirectional pressure. The radial compression of the O-ring can provide initial contact pressure. When the system pressure increases, the O-ring transforms it into another contact pressure, so the contact pressure of the sealing element is automatically adjusted to ensure sealing performance under all working conditions.
