The DBH 8155 seal is a single-lip radial shaft seal that mounts on the shaft to retain lubricant and prevent contaminants from entering. Its A 141 design and dimensions —50.8 mm shaft diameter and 14.28 mm height— make it suitable for rotating equipment where axial space is limited. MR Accesorios Industriales carries this official brand and advises you so you choose the right seal for your application.

This item is a radial shaft seal from the DBH line, identified with code 8155. According to the product page data, it corresponds to a shaft with a diameter (d) of 50.8 mm and a total height (h) of 14.28 mm. The A 141 design defines the geometry of the lip and the metal body. The housing diameter is listed as 0 mm, a value that usually indicates the measurement is confirmed against a sample or drawing; therefore, before requesting a quote, it is advisable to verify the bore diameter of the housing where it is mounted.

Seals of this type are used in gearboxes, pumps, electric motors, transmission shafts and continuous process equipment. Their function is twofold: to retain the oil or grease inside the assembly and to block dust, water or particles that wear down the bearings. In food, chemical or water treatment plants, choosing the right lip compound makes the difference in the service life of the seal.

To select a seal properly, three things must be checked: the shaft diameter, the housing diameter and the height. Rotation speed, operating temperature and the type of lubricant also matter. An incorrectly sized lip or a material incompatible with the fluid causes premature leaks. If you have doubts, send us the shaft and housing measurements; we cross-check them against the manufacturer's product page.

If you need a nearby size or an equivalent, send us the full code shown on the old seal, the brand and the measurements taken with a caliper. With that data we search the DBH line and other compatible alternatives. We do not invent sizes: if the housing diameter is not on the product page, we confirm it with the manufacturer before offering you a solution.
