The DBH 6889 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. With dimensions of 65 mm shaft diameter, 85 mm housing and 12 mm height, and an Lz-R design, it is used in gearboxes, pumps and industrial equipment where preventing leaks is critical. MR Accesorios Industriales carries this official brand and advises you so you choose the correct seal for your application.

The DBH 6889 is an Lz-R type radial shaft seal, which indicates a configuration with a sealing lip and a specific design for applications with rotating shafts. Its standardized dimensions are 65 mm shaft diameter (d), 85 mm housing diameter (D) and 12.00 mm height (h). These dimensions allow it to be mounted in standard housings and to replace equivalent seals from other brands. The designation 6889 corresponds to the manufacturer code DBH, which MR carries as an official brand.

Radial shaft seals such as the DBH 6889 are used in a wide variety of equipment: gearboxes, centrifugal pumps, electric motors, conveyor rollers and agricultural or construction machinery. Their main function is twofold: to retain the oil or grease inside the mechanism and to prevent the entry of dust, water or particles that accelerate the wear of bearings and gears. In environments with high contamination or moderate speeds, a well-selected lip seal extends the service life of the assembly.

To correctly install a DBH 6889 oil seal, verify that the shaft has the proper 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 tool that bears on the outer diameter so as not to damage the seal. The selection must consider peripheral speed, operating temperature and the chemical compatibility of the elastomer with the fluid. If you have doubts, consult us with your equipment data.

If you need an oil seal equivalent to the DBH 6889 or a neighboring size, the most practical thing is to send us the full code, the shaft, housing and height dimensions, and a photo of the old seal if possible.
