The DBH 5755 radial shaft seal is a lip seal that mounts on a rotating shaft to retain lubricant and block the entry of dust, water or particles. With a 12.70 mm shaft diameter, 31.75 mm housing diameter and 9.52 mm height, and Lx design, it is a common replacement part in equipment with small-section shafts. MR Accesorios Industriales sells this brand and advises you on choosing the right seal for your application.

This item is a DBH 5755 radial shaft seal, identified by its designation 5755. Its dimensions are 12.70 mm shaft diameter (d), 31.75 mm housing diameter (D) and 9.52 mm height (h). The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. The series nomenclature lets you quickly locate the part in the catalogue and compare it against the original size before replacing it.

Seals of this size are used in pumps, small electric motors, gearboxes, compressors, machine tools and power transmission equipment where the shaft has a small section. They also appear in agro-industrial applications and in washing or process equipment, where the seal must contain the oil and stop the entry of water and dirt. If the seal works in an environment with abrasive dust, it is advisable to check the condition of the lip and the shaft before replacing it.

When mounting a radial shaft seal, keep in mind that the shaft must not have burrs or marks in the contact area: a scratched surface ruins the lip within a few hours. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and place the seal perpendicular to the shaft, without hitting it from the side. If the housing has a shoulder or the shaft is off-centre, the seal will not work properly even if the size is correct.

It also helps if you tell us the equipment where it is mounted and the type of lubricant it uses, to better guide the selection.
