The DBH 8122Pol oil seal is a single-lip radial shaft seal designed for rotating shafts. Its function is to retain lubricant inside the assembly and prevent the ingress of contaminants, particles and moisture. It is installed in gearboxes, pumps, electric motors and industrial equipment where the shaft rotates on bearings or bushings. MR Accesorios Industriales supplies this brand and advises you on choosing the right oil seal. Its A 203 design and 15.00/20.00 mm height make it suitable for housings with a shoulder or for assemblies requiring a longer lip.

This DBH 8122Pol oil seal is identified by its designation 8122Pol and corresponds to a single-lip radial shaft seal. Its main dimensions are: shaft diameter 145 mm, housing diameter 170 mm and height 15.00/20.00 mm. The A 203 design indicates a specific construction configuration within the DBH line. The sealing lip, generally made of elastomer, runs on the rotating shaft, while the outer body is seated in the cavity with an interference fit. The variable height allows the seal to be adapted to different housing depths.

Typical applications for this oil seal include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and transmission equipment. In all these cases, the oil seal protects the bearings and the lubricant from external contamination, and prevents leaks that could affect equipment performance. It is also used in agricultural machinery, mining equipment and hydraulic systems where the shaft rotates at moderate speeds and there is exposure to dust, water or chips.

To correctly select an oil seal, take into account the shaft diameter, housing diameter, height and design type. Check that the shaft surface is ground and has adequate hardness, and that the housing has the recommended chamfer and roughness. Installation must be done with tools that do not damage the lip; lubricate the lip with the same oil or grease used in the equipment before inserting it. If the shaft shows wear, consider an oil seal with an auxiliary lip or a wear sleeve.
