The DBH 8399Vit radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of contaminants, such as dust or water, that accelerate the wear of bearings and bushings. With dimensions of 38 mm shaft, 50 mm housing and 6 mm height, and an Lx-R design, it is a common replacement part in industrial equipment. At MR Accesorios Industriales we carry it as part of our line of seals and shaft seals.

This item is a DBH radial shaft seal, identified with the designation 8399Vit. Its dimensions are: shaft diameter (d) 38 mm, housing diameter (D) 50 mm and height (h) 6.00 mm. The Lx-R design indicates a configuration with a retaining lip and a spring that ensures constant contact on the shaft. It is intended to be press-fitted into the housing and seal against the surface of the moving shaft. DBH is a brand that MR carries, which guarantees a reliable alternative within our range of seals.

Typical applications for this seal include gearboxes, pumps, electric motors, rollers and power transmission equipment. In general, it is used in assemblies where there is a rotating shaft that must be isolated from the outside environment. It also appears in machine tools, conveyors and lubrication systems. It is always advisable to verify that the temperature, speed and lubricant type conditions are compatible with the material of the lip and the seal body, data confirmed with the manufacturer's technical data sheet.

To correctly select and install a seal such as the 8399Vit, take into account the cleanliness of the surfaces, the condition of the shaft (free of scratches or wear) and the concentricity of the housing. The lip must be lubricated before installation to prevent damage at start-up. The installation pressure must be uniform, using a tube or socket that bears on the outer diameter. If the shaft shows a worn track, consider using a seal with an offset lip or a repair sleeve. These practices extend the service life of the seal.

If you need an equivalent or a nearby size, the most practical thing is to send us code 8399Vit or the current dimensions (shaft diameter, housing and height). With that data we can look for alternatives within our DBH seal line or other brands we carry. We can also advise you on the most suitable design according to the type of application. Remember that the dimensions must match the housing and the shaft to ensure effective sealing.
