The DBH 5979 radial shaft seal is a lip seal that blocks the passage of oil or grease in equipment with a rotating shaft. Its dimensions —44.45 mm shaft, 77.75 mm housing and 12.70 mm height— place it in power transmission and machinery applications where lubricant must be retained and dust or water kept out. MR Accesorios Industriales carries this official brand and can source it by part number so you can order it without hassle.

The DBH 5979 is a seal with an Mz design, with the three dimensions that define its mounting: shaft diameter 44.45 mm, housing diameter 77.75 mm and height 12.70 mm. The Mz design corresponds to a seal with a sealing lip and metal body, designed to be press-fitted into a machined cavity. It is a component of the radial shaft seal and seal category, and its function is simple: keep lubricant in and contaminants out.

It is used in gearboxes, pumps, electric motors, transmission shafts and process equipment where a shaft rotates inside a housing. It also appears in agricultural machinery, conveyors and plant equipment. When the original seal hardens, tears or starts to fail, the typical sign is an oil stain around the shaft or a drop in oil level in the sump.

To install it, check that the shaft has no burrs or wear and that the housing is clean and free of dents. Lubricate the lip before fitting and seat the seal squarely, without twisting it. If the shaft has a marked groove, a different lip size or a spring-loaded seal may sometimes be advisable. Selection depends on speed, temperature and the type of lubricant, so if you have any doubts, ask us.
