Oil seals (turn direction)

Oil seals (turn direction)

Oil seals with turn direction have specific characteristics and applications that distinguish them from standard oil seals.

These seals are designed with a helical or spiral profile (dral) on the sealing lip. This profile helps return fluids, such as oil, to the space they seal. It can help keep dust, dirt or other contaminants away from the sealing area. The direction of rotation of the shaft (anti-clockwise or clockwise) determines how the spiral profile works. Oil seals with turn direction are used in situations where there is a high rotational speed or an increased risk of leakage. The helical pattern on the sealing lip reduces oil loss even at higher rotational speeds.
