The DBH 9403 radial shaft seal is a lip seal mounted in cylindrical housings to retain lubricant and exclude contaminants on rotating shafts. With dimensions of 35 mm shaft diameter, 64 mm outer diameter and 8 mm height, and Lx design, it is a compact solution for equipment where axial space is limited. MR Accesorios Industriales carries this official brand and advises you so you choose the correct seal for your application.

The DBH 9403 is a radial-type seal with a sealing lip, identified by its numerical designation and its standardised dimensions: 35 mm shaft diameter (d), 64 mm housing diameter (D) and 8.00 mm overall height (h). Its Lx design indicates a specific construction within the DBH line, combining a main lip with a secondary exclusion lip. It is made with elastomers resistant to mineral oils and greases, and its metal case ensures a firm fit in the housing. It is a direct replacement part for equipment that requires this exact size.

Radial shaft seals such as the DBH 9403 are used in gearboxes, pumps, electric motors, transmission shafts, rollers and continuous process equipment. Their function is twofold: to prevent lubricant leaks to the outside and to block the entry of dust, water or particles that accelerate wear on bearings and gears. In industrial plants, they are commonly found in packaging lines, conveyors, mixers and agricultural machinery. Whenever there is a rotating shaft inside a lubricated housing, a seal of these characteristics protects the internal components and extends the service life of the assembly.

To select a seal correctly, check that the shaft, housing and height dimensions match those of your equipment's housing and shaft. The shaft surface must be ground and free of grooves so as not to damage the lip; a minimum hardness and controlled roughness are recommended. During installation, lubricate the lip with the same oil used in the equipment, insert the seal perpendicular and apply uniform pressure on the case, never on the lip. If the housing has burrs or wear, correct them before installing the new part to ensure effective sealing.

If you need a seal equivalent to the DBH 9403 or a nearby size, gather the equipment data: shaft diameter, housing diameter, height and type of lubricant. With that information, the technical team at MR Accesorios Industriales can offer you alternatives from other brands or configurations within the same seal category. We can also evaluate variants with an additional lip, double lip or special materials for aggressive temperatures or fluids. The idea is that you do not end up with equipment stopped for a sealing part.
