The DBH 6163 is a radial shaft lip seal that keeps lubricant in and contaminants out of rotating shaft assemblies. It fits a 31.75 mm shaft, a 50 mm housing bore and an 8 mm width, and is pressed into the housing while its flexible lip runs against the shaft. Because the lip wears over time, it is treated as a replacement item at each maintenance interval.

The code 6163 identifies this seal within the DBH line. Its dimensions are: shaft 31.75 mm, housing 50 mm, width 8.00 mm. The Mz design uses a single sealing lip with a spring, a common configuration for lubricated rotating shafts. The 31.75 mm shaft size matches 1 1/4 inch, so the seal appears often on equipment built with inch dimensions.

You will find this seal on gearboxes, pumps, electric motors, reducers and other power transmission equipment, as well as on fan shafts, mixers, conveyors and industrial or agricultural machines. Anywhere a lubricated bearing or bushing sits on a rotating shaft, the seal protects the sealing area.

Before installation, check that the shaft and housing bore are clean and free of burrs or scratches. Apply the same oil or grease used in the equipment to the lip. Press the seal in with a driver that contacts only the outer ring, never the lip. Shaft runout should stay within the limits allowed for radial shaft seals. If the shaft is worn, a repair sleeve is an option.

If you need a different size or an equivalent, send the code 6163 or the dimensions 31.75 x 50 x 8 mm and we will look for alternatives in other brands or configurations. A photo of the old part or the markings on the seal helps avoid mistakes.
