The DBH 8786 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants in rotating equipment. Its dimensions of 54 mm shaft, 79.35 mm housing and height of 12.70/19.00 mm make it suitable for assemblies where axial space is limited and a reliable seal is required. It is manufactured with an elastomer resistant to oils and greases, and is sold at MR Accesorios Industriales for replacement and industrial maintenance.

This item is a DBH 8786 radial shaft seal, with designation 8786 and design A 103-H-H. Its dimensions are 54 mm shaft diameter, 79.35 mm housing diameter and a height that ranges between 12.70 and 19.00 mm. The A 103-H-H design indicates a configuration with a sealing lip and reinforced body, suitable for rotating shafts. The DBH brand is an official brand that MR carries, which ensures standard dimensions and replacement availability.

Typical applications of this seal include gearboxes, pumps, electric motors, rollers and power transmission equipment. In environments with dust, water or chips, the sealing lip prevents oil leakage and the entry of particles, extending the service life of bearings and gears. It is common in production lines, food plants and conveyor systems that operate with permanent lubrication.

For correct installation, verify that the shaft has the appropriate hardness and roughness, and that the housing is clean and free of burrs. Lubricate the lip with the same oil used in the equipment before inserting it, and use an installation tube that presses on the outer diameter so as not to damage the seal. Selection must consider peripheral speed, operating temperature and the chemical compatibility of the elastomer with the fluid to be retained.
