Its dimensions —30.10 mm shaft, 61.90 mm housing and 11.90 mm height— and its Mz design make it suitable for assemblies that require reliable sealing. MR Accesorios Industriales carries this brand as part of its seals and oil seals line, with technical advice to select the right part.

This item is a DBH radial shaft seal, identified by part number 5784. Its dimensions are 30.10 mm for the shaft diameter (d), 61.90 mm for the housing diameter (D) and 11.90 mm height (h). The Mz design corresponds to a specific construction configuration within the DBH line, which combines a sealing lip and a metal reinforcement structure. It is a precision part intended for rotating shafts where oil or grease must be contained and dust, water or particles kept out.

Radial shaft seals such as the DBH 5784 are used in gearboxes, pumps, electric motors, drive shafts and industrial equipment in general. Their function is twofold: to retain the lubricant inside the assembly and to act as a barrier against external agents. In applications with continuous rotary motion, the lip must maintain uniform contact on the shaft to minimize leaks and wear. They are common in machinery maintenance, replacement of worn seals and manufacturing of new equipment.

To install a radial shaft seal correctly, check that the shaft and housing are clean, free of burrs and scratches, and that the dimensions match those of the seal. The Mz design may require a specific lip orientation depending on the direction of rotation or the working pressure. Lubricate the lip before inserting it and use an installation tool that presses on the outer diameter, never on the lip. If the shaft shows wear, consider a nearby size or a repair sleeve.
