The DBH 6456 is a radial shaft seal built to keep lubricant where it belongs and to block contaminants from reaching the bearing cavity of rotating machinery. Its Mx configuration combines a sealing lip with a metal case, and its dimensions are 57.15 mm on the shaft, 85.63 mm in the housing bore and 17.85 mm overall height, which suits assemblies with limited axial room. Pumps, electric motors, gear reducers and gearboxes are common places to find this seal. MR Industrial Accessories supplies this brand and can help you confirm the correct replacement.

This seal belongs to the DBH line and carries the code 6456. In the Mx design, the outer metal case is pressed into the housing while the lip rides against the rotating shaft, forming the barrier that retains oil or grease and shields the bearings from outside matter. The three figures above are the ones to check against your equipment: shaft 57.15 mm, housing 85.63 mm, height 17.85 mm.

You will typically see this seal in centrifugal pumps, electric motors, speed reducers, gearboxes and other transmission equipment. In every one of those cases its job is the same: hold the lubricant inside the assembly and keep dust, water and particles out, since those contaminants shorten bearing life. Treat it as a wear item and replace it once you notice leaking oil or unusual noise from the shaft area.

Installation calls for a few basic precautions. Inspect the shaft for burrs, nicks or grooves that could cut the lip, and coat the lip with the same oil or grease the equipment uses before sliding it into place. The housing bore should be clean and undistorted. When choosing a replacement, dimensions alone are not enough; consider the fluid being sealed, the operating temperature and the shaft speed as well. The Mx design covers general duties, and if your equipment runs under tougher conditions we can point you toward more resistant options.

For an equivalent to the DBH 6456, the fastest route is to give us the complete code or the three dimensions. From there we can search within the same brand or among the other brands we carry. If the original seal has a special characteristic, such as an extra lip or a material intended for elevated temperatures, tell us and we will factor that into the search.
