The DBH 5354 oil seal is a single-lip radial shaft seal that mounts on rotating shafts to retain lubricant and block the entry of dust, water or particles. With a 55 mm shaft diameter, 75 mm housing and 12 mm height, it covers industrial applications where bearings and gearboxes must be protected. Its Lz design works with a sealing lip that bears on the shaft and a metal case that fits under pressure in the housing.

This DBH 5354 oil seal has the nominal dimensions of 55.00 mm shaft diameter, 75.00 mm housing diameter and 12.00 mm height. The Lz design corresponds to a single-lip radial shaft seal with a spring, intended for rotating shafts with grease or oil lubrication. The outer case is metal and the sealing lip is elastomer, which gives it flexibility to compensate for small misalignments and vibrations typical of operation. It is installed under pressure in the housing and seals against the moving shaft.

It is used in gearboxes, pumps, electric motors, conveyor rollers and transmission equipment where lubricant leaks and the entry of contaminants must be prevented. It also appears in applications exposed to dust or sprayed water, provided the shaft and housing have the right dimensions and finish. It is a wear part: it should be checked when there are oil leaks, noise or play in the associated bearing.

To install it, check that the shaft diameter is within the tolerance recommended for radial shaft seals and that the housing has no burrs or marks. Lubricate the lip with the same grease or oil as the equipment before inserting it, and do it with a tube or press that bears on the outer edge, never on the lip. If the shaft shows wear, consider a neighboring size or a seal with the lip in another position. The selection depends on the speed, the temperature and the type of fluid to be retained.
