MR Accesorios Industriales supplies it as an official brand.

This item is a radial shaft seal from the DBH brand, identified with part number 5931. Its dimensions are 15.77 mm shaft diameter (d), 25.41 mm housing diameter (D) and 5.20 mm height (h). The Lz design corresponds to a single-lip configuration with spring, intended for lubricated rotating shafts. It is a small-section seal, suitable for mechanisms where axial space is limited and a reliable closure is required.

Seals of this type are used in gearboxes, electric motors, pumps, compressors, transmission shafts and power transmission equipment in general. They also appear in machine tools, washing equipment and conveyor systems. Their function is twofold: to prevent oil or grease leaks to the outside and to protect bearings and gears from the entry of contaminants, which extends the service life of the assembly.

To select a seal, check the shaft diameter, the housing diameter and the available height. The Lz design defines the lip type and its geometry, so the mounting orientation should be respected: the lip faces the lubricant side. The shaft surface must be ground and free of burrs, and the housing clean and undamaged. Poor installation, with the lip inverted or knocked, causes premature leaks.
