The DBH 8922 radial shaft seal is a lip seal that mounts between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. Its dimensions —50 mm shaft, 70 mm housing and 8 mm height— place it in medium-sized transmission equipment, such as gearboxes, pumps and electric motors. MR Accesorios Industriales carries the DBH brand within its line of seals and oil seals.

This item is a seal with an Lx design, with the following dimensions: shaft diameter (d) of 50 mm, housing diameter (D) of 70 mm and height (h) of 8.00 mm. The Lx design corresponds to a seal with a sealing lip and a metal body, intended for rotating shafts with lubrication. The code 8922 identifies this size within the DBH line. Before installing, check that the housing and the shaft match these dimensions; any difference requires another reference.

Typical applications of a 50 x 70 x 8 mm seal include gearboxes, speed reducers, centrifugal pumps, electric motors and power transmission equipment in general. In all cases, the seal performs the function of confining the oil or grease inside the assembly and preventing contaminants from entering from the outside. It is a wear part: over time, the lip hardens or wears and lubricant loss appears.

To correctly select a seal, in addition to the dimensions, take into account the shaft speed, the working temperature and the type of lubricant. The Lx design is suitable for applications with a rotating shaft and oil or grease lubrication. During installation, lubricate the lip before inserting it, check that the shaft has no burrs or marks and place the seal perpendicular to the shaft, without striking it directly. If the housing shows wear, consider a prior repair.
