The DBH 5138Vit radial shaft seal is a lip seal mounted in the housing that closes on the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions of 15.00 mm shaft, 30.00 mm housing and 7.00 mm height place it in small-sized equipment, where space is limited and rotation speed is usually high. It is a wear part: when oil loss appears or dirt enters, it is replaced.

This item is a seal from the DBH line, identified as 5138Vit. Its designation corresponds to a single lip profile with spring, and the dimensions we publish are those shown in the data sheet: 15 mm shaft diameter, 30 mm housing diameter and 7.00 mm height. The Lx design corresponds to a seal with a sealing lip and metal body, intended to be press-fitted into a machined cavity. The lip elastomer works against the shaft and maintains contact through the action of the internal spring.

It is used in small gearboxes, low-power electric motors, centrifugal pumps, fans, mixers and power transmission equipment where oil or grease must be separated from the environment. It also appears in machine tools, roller shafts and similar applications with continuous rotation. In all cases it performs two functions: retaining the lubricant inside the assembly and preventing the entry of contaminants that accelerate the wear of bearings and gears.

To select it, verify that the shaft and housing diameters match the values in the data sheet, and that the cavity width accommodates the 7.00 mm height. The shaft surface must be ground and free of burrs; a mark or a deep scratch ruins the lip in a few hours. Before mounting, lubricate the lip with the same grease or oil as the equipment, and insert the seal perpendicular to the shaft, with a tube or socket that rests on the outer ring, never on the lip. If the shaft has play or is pitted, it is advisable to evaluate replacing the shaft or using a wear sleeve.
