The DBH 8120Pol radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 28.58 mm shaft diameter, 41.20 mm housing and 6.20 mm height make it suitable for equipment with compact spaces. The Mz-R design combines a sealing lip with an exclusion element that improves performance in dusty or dirty environments. MR Accesorios Industriales supplies this brand as part of its seals and oil seals line for industrial maintenance.

This item is a radial shaft seal from the DBH brand, identified with the designation 8120Pol. Its standardized dimensions are: shaft diameter (d) of 28.58 mm, housing diameter (D) of 41.20 mm and height (h) of 6.20 mm. The Mz-R design corresponds to a configuration with a sealing lip and an auxiliary exclusion lip, intended for applications where particles are present. The outer body is made of elastomer and the lip works on the shaft through controlled interference.

Typical applications for this seal include gearboxes, pumps, electric motors, reducers and power transmission equipment. Due to its compact size, it is used in assemblies where axial space is limited and effective sealing against oil or grease leaks is required. It is also common in agricultural machinery, material handling equipment and hydraulic systems operating under exposure to dust or moisture.

For installation, check that the shaft and housing diameters match the indicated dimensions. The shaft must have a polished surface, free of burrs or splines that could damage the lip. Lubricate the lip with the same oil or grease used in the equipment before inserting it and use an installation tube that presses on the outer diameter, never on the lip. The 6.20 mm height should sit flush or slightly recessed according to the housing design.
