The DBH 9128 oil seal is a single-lip radial seal with a spring, designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or contaminating particles. With dimensions of 38 mm shaft diameter, 50 mm housing and 10 mm height, and an Lx design, it is a common replacement part in pumps, electric motors, gearboxes and transmission equipment. MR Accesorios Industriales supplies this brand and helps you identify the correct size for your equipment.

The DBH 9128 is a radial shaft seal with 38 mm shaft diameter (d), 50 mm housing diameter (D) and 10 mm height (h). Its Lx design indicates a single-lip configuration with a spring, intended for rotating lubricated shafts. The sealing lip, generally made of elastomer, runs on the shaft and the spring maintains contact pressure to compensate for wear. The outer metal case ensures a firm fit in the housing. This combination of dimensions and design makes it suitable for limited radial spaces and moderate speeds.

Typical applications for this oil seal include centrifugal pumps, electric motors, gearboxes, gear cases, conveyor rollers and power transmission equipment. In all cases, its function is twofold: retain the oil or grease of the bearing and block the entry of external contaminants. It is a wear part that is usually replaced during preventive or corrective maintenance, when leaks or noise are detected in the assembly. It is also used on fan shafts, mixers and agricultural or general industrial machinery.

To correctly install an oil seal such as the DBH 9128, verify that the shaft is clean, free of burrs and deep marks, and that the sealing surface has the appropriate hardness and roughness. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, with the lip facing the lubricant side. Avoid striking the lip during installation. When selecting a replacement, consider not only the dimensions (38 x 50 x 10 mm) but also the type of elastomer, the spring and the lip design, according to temperature, speed and fluid conditions.
