For rotary equipment, the DBH 5858 radial shaft seal keeps lubricant where it belongs and keeps dust, water and particles out. It fits a 31.75 mm shaft, a 42.87 mm housing bore and a 4.68 mm height, so it works in assemblies with limited axial room. The Lz designation points to a lip-and-spring configuration that runs with low friction and holds up to wear.
The code breaks down simply: 5858 is the DBH part number, and the three figures that follow in the catalog listing are shaft 31.75 mm, housing bore 42.87 mm and height 4.68 mm. In the Lz design, an elastomer lip is pressed against the rotating shaft by a spring, while the outer body stays put in the housing. This is a standard replacement item wherever a shaft turns inside a bore.
You will find seals like this one in gear reducers, pumps, electric motors, gearboxes and bearing positions on general machinery. The job is always the same: hold oil or grease in and keep contaminants out, which protects the bearings downstream. Conveyors, agitators, machine tools and transmission equipment are common homes for it. Speed, temperature and the lubricant in use are the factors that decide whether a given seal suits the application.
Installation starts with checking that the shaft and housing match the stated dimensions. The shaft surface should be smooth and free of burrs so the lip is not cut during fitting. Coat the lip with the same oil or grease the equipment runs on, then press the seal in squarely with a tube or press that contacts only the outer diameter. Do not strike the lip. If the housing bore is worn, a seal with a larger outer diameter or a repair sleeve may be the better route.
