Weinheim, Germany – Freudenberg Sealing Technologies has developed a new rotary seal for wet-running applications and pressures up to eight bar.
Named the Gerromatic, the seal is equipped with a wave-shaped sealing lip, not a rotation-symmetrical design. Freudenberg said this results in a sinusoidal contact pattern.
As the shaft rotates, each point of the seal lip repeatedly coats a different area of the shaft, moistening it with the medium to reduce friction and the usual temperature rise at the sealing area.
