The DBH 8550Pol radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of dust, water or contaminating particles. With dimensions of 52 mm shaft diameter, 72 mm housing diameter and 9 mm height, it is press-fitted into gearboxes, covers and reduction gear housings. It is a wear part that should be replaced when oil leakage or shaft play appears. MR Accesorios Industriales supplies it as an official brand.
This item is a seal from the DBH line, identified as 8550Pol. Its nominal dimensions are 52 mm for the shaft diameter (d), 72 mm for the housing diameter (D) and 9.00 mm height (h). The Lx-R-H design indicates a configuration with a retaining lip, reinforced body and secondary exclusion lip. The elastomer and internal spring ensure sealing under continuous rotation conditions. It is supplied with the exact dimensions indicated, with no need for additional adjustments.
Typical applications for this seal include gearboxes, pumps, electric motors, transmission shafts and process equipment. In the food, chemical or water treatment industries, where contamination is critical, this type of seal prevents the ingress of liquids and particles. It is also used in reducers and rollers of road machinery. Its compact size makes it suitable for tight spaces where a reliable, easy-to-replace closure is required.
To correctly select a seal, verify that the shaft and housing dimensions match those of the seal. The shaft must have a polished surface, free of grooves or wear, and the housing must be clean and free of burrs. During assembly, lubricate the lip with the same oil used in the equipment and use an installation tool to avoid damaging the spring. Poor alignment or a scratched shaft cause premature leaks. If in doubt, consult our technical team.
