The DBH 8271Pol radial shaft seal is a lip seal designed to close off the passage of oil or grease on rotating shafts, housed in a 90 mm housing. Its Mx-R design and 10 mm height make it suitable for equipment with limited axial space. It is used in gearboxes, pumps, electric motors and transmissions where preventing leaks and dust ingress is key. MR Accesorios Industriales supplies this brand and advises you on choosing the correct size.

This item is a radial shaft seal from the DBH line, identified as 8271Pol. Its nominal dimensions are 74 mm shaft, 90 mm housing and 10 mm height. The Mx-R design corresponds to a seal with a sealing lip and metal body, intended to be press-fitted into the housing and seal against the shaft. The 8271Pol nomenclature allows it to be located within the manufacturer's catalogue and to confirm material or spring variants if your application requires it.

Typical applications for a seal of these dimensions include gearboxes, centrifugal pumps, electric motors, rollers and transmission shafts. In all cases, the function is to retain the lubricant inside the assembly and block the entry of external contaminants such as dust or water. It is a critical part in equipment that operates continuously, because a leak can cause loss of lubricant, premature bearing wear and unplanned downtime.

To install this seal, verify that the shaft has the appropriate hardness and roughness, with no burrs or marks that could damage the lip. The housing must be clean and free of deformation; it is advisable to lubricate the lip with the same oil used in the equipment before inserting it. The 10 mm height allows it to be housed in shallow cavities, but make sure the seal sits fully seated and perpendicular to the shaft. If the equipment operates with high vibration or temperature, consider an alternative material.

If you need to replace this seal and cannot find the exact size, we can look for an equivalent from other brands or a nearby size that fits your shaft and housing. To do this, send us the part number 8271Pol or the dimensions of your shaft, housing and height. We can also quote the seal in different material qualities depending on the fluid and working temperature. The idea is that you are not left with equipment down because of a sealing part.
