The DBH 1389Vit radial shaft seal is a lip seal that closes off the passage of oil or grease at the point where a shaft rotates inside a housing. Its Lx-R H design combines a sealing lip with a dust lip, so that it retains lubricant inward and blocks the entry of dust, water or particles from outside. It is press-fitted into the cavity and runs on the shaft surface, which is why the shaft, housing and height dimensions must match those of the equipment.

This item is an oil seal from the DBH line, identified with the code 1389Vit. Its dimensions are 46 mm shaft diameter, 56.40 mm housing diameter and 7.00 mm height, and its design is Lx-R H. Those three dimensions define whether or not it fits into the cavity: the outer diameter seats in the housing, the lip runs against the shaft and the height determines how far it protrudes from the face. Before ordering it, compare the three values with the old oil seal or with the equipment drawing.

Radial shaft seals of this type are used in gearboxes, pumps, electric motors, drive shafts, rollers and process equipment. In each case they perform the same function: separating the lubricated side from the environment. When the equipment operates with dust, chips or water, the dust lip of the Lx-R H design helps keep the contaminant from reaching the main lip. That is why it is advisable to check the condition of the shaft and the housing before replacing the part.

To select an oil seal correctly, verify that the shaft and housing diameters match the original part, that the height is compatible with the cavity and that the lip material is suitable for the lubricant and the working temperature. When installing it, lubricate the lip, keep the spring in position and place the oil seal perpendicular to the shaft, without striking it unevenly. A lip installed crooked or on a scratched shaft loses sealing within a few hours.
