The DBH 8403Pol is a radial shaft seal that keeps lubricant where it belongs and keeps dirt out of rotating equipment. Its Lx-R lip arrangement pairs a primary sealing lip with a second lip that acts as an exclusion barrier, which helps in areas where dust and grit are present. The designation reads as shaft 38 mm, housing 58 mm and height 8.50 mm, so it drops into the bore of gearboxes, pumps and motors that use that size. MR Industrial Accessories LLC supplies it through its seals and oil seals line.

The part carries the DBH brand and the code 8403Pol. Its three working dimensions are a 38 mm shaft, a 58 mm housing bore and an 8.50 mm overall height. The Lx-R layout means one lip does the sealing against the rotating shaft while the other faces outward and blocks particles from reaching the sealing edge. The body is an elastomer element bonded to a metal case, which allows it to be pressed into a cylindrical housing.

Where you will see this size: gear reducers, centrifugal pumps, electric motors and other power transmission assemblies. In each case the seal holds oil or grease inside the housing and stops dust, water or chips from travelling along the shaft into the mechanism. A 38 mm shaft running in a 58 mm bore with 8.50 mm of axial room is a widely used combination, which makes the 8403Pol a frequent replacement item on maintenance lists.

Before ordering, confirm the three numbers against the equipment: shaft, bore and height. A seal with an Lx-R profile suits positions exposed to contamination, because the outer lip adds a barrier in front of the sealing lip. When fitting, coat the lip with the same lubricant the machine uses, keep the seal square to the shaft, and press it in without hammering on the lip. If the shaft surface is scored or rough, address that first or look at a seal with the lip running in a different position.

If the 8403Pol is not what you need, we can look for a match. Alternatives from other brands are available, and we can narrow the options using your shaft and bore measurements. Having the original code, the dimensions or a photo of the old part on hand makes identification faster. We can also discuss which elastomer compound and which lip configuration fit the fluid and the operating temperature of your application.
