The DBH 8155 oil 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 supplies this brand and advises you so you can choose the right seal for your application.

This item is a radial shaft seal from the DBH line, identified by code 8155. According to the product data, it corresponds to a shaft 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 case. 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 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 correctly, three things must be checked: shaft diameter, housing diameter and height. Rotation speed, operating temperature and 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 data sheet.

To quote 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. If the housing diameter is not on the data sheet, we confirm it with the manufacturer before offering you a solution.
