The DBH 8428 seal is a radial seal of A 124 design that is placed between a rotating shaft and a fixed housing to retain lubricant and exclude contaminants. Its dimensions of 120.5 mm shaft diameter, 152.4 mm housing and height of 15.00/22.80 mm make it suitable for equipment with large-diameter shafts. MR Accesorios Industriales sells this official brand and advises you so that you choose the correct seal according to your application.

This DBH 8428 seal has a shaft diameter of 120.5 mm, a housing diameter of 152.4 mm and a height of 15.00/22.80 mm. The A 124 design corresponds to a radial seal with a sealing lip and metal body, designed to be press-fitted into the housing. The variable height indicates that the mounting section and the lip can have different dimensions, which is common in seals with reinforcement or an integrated dust lip. Always verify these dimensions against the housing and the shaft before replacing.

Radial seals of this size are used in reducer gearboxes, pumps, mills, mixers and power transmission equipment with large-diameter shafts. They also appear in conveyor rollers, presses and process machinery where oil or grease must be contained and the entry of dust or water prevented. As it is a wear component, it is advisable to check it at each scheduled maintenance and replace it when leaks appear or the lip hardens.

To select the correct seal, take into account the shaft diameter, the housing diameter and the available height. The A 124 design can vary in the shape of the lip and in the presence of a dust lip, so it is important to respect the original dimension or ask if there is a compatible variant. Mounting must be done with a suitable tool, lubricating the lip and avoiding blows that could damage the spring or the sealing edge. Careful cleaning of the housing and the shaft extends the service life.
