The DBH 8399Pol radial shaft seal is a lip seal that mounts on the shaft and seats in the bore of a housing or box. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles. With a 38 mm shaft, 50 mm housing and 6 mm height, it is a compact size for equipment where axial space is limited.
This item is a seal with an Lx-R design, with the following dimensions: shaft diameter 38 mm, housing diameter 50 mm and height 6.00 mm. The Lx-R design corresponds to a spring-loaded sealing lip and a construction that combines an outer metal body with the elastomeric element. It is a radial-section seal, intended for rotating shafts with internal lubrication.
It is used in gearboxes, pumps, electric motors, rollers and transmission equipment where oil or grease must be contained and contamination from the outside avoided. It is commonly found in applications with moderate speeds and shafts that do not show significant runout. It is also used as a closure in split plummer block housings and in assemblies built with bearings.
To select it, check that the shaft diameter is within the tolerance recommended for radial shaft seals and that the contact surface is ground and free of marks. The housing must have the right diameter and depth for the seal to seat without deforming. If the shaft shows wear, consider a repair sleeve or a nearby size. Lubricating the lip before installation helps prevent damage at start-up.
If you need an equivalent or a different size, send us the part number 8399Pol or the shaft, housing and height dimensions. We can also look for a seal with the same Lx-R design in another brand or with a different elastomer if the working environment requires it. We work with in-house manufacturing, so we can guide you according to the application.
MR Accesorios Industriales carries the DBH brand as an official brand. If you want to ask about a nearby size, write to us on WhatsApp with the part number 8399Pol and we will reply with the alternative that best fits your equipment.
