Keeping lubricant where it belongs and dirt out of a bearing housing often comes down to one small component: the radial shaft seal. The DBH 8203 is a lip seal built for a 66.72 mm shaft, a 92.02 mm housing bore and a 12.70 mm height, dimensions that suit rotating shaft positions where room is tight. MR Industrial Accessories supplies this brand and can walk you through picking the right seal for the job.
The code tells you the series, and the numbers tell you the fit. This seal carries the designation 8203 and belongs to the Mz design family, which pairs a sealing lip with a metal outer body. Shaft side measures 66.72 mm, bore side 92.02 mm, overall height 12.70 mm. That combination of lip and metal case is what lets it hold oil or grease in place while blocking dust and water from working its way in. Think of it as a wear part for rotating shafts on industrial machinery, not a one-time fit.
Where does it show up? Gearboxes, pumps, electric motors, line shafts and process equipment are typical homes. The seal sits between the rotating shaft and the stationary housing, keeping the lubricant on the bearing side and contamination on the outside. It fits positions running at moderate speeds where the seal has to stand up to continuous friction and still do its job.
Selection starts with measurement. Confirm the shaft diameter, the housing bore and the height against your equipment before ordering, since a mismatch on any one of the three will not seat correctly. If you are matching an existing part, look at the Mz designation as well as the elastomer compound and the spring, because those details affect how the lip behaves in service. On installation, coat the lip with lubricant, keep it away from sharp edges, and check that the shaft surface is free of burrs, nicks or scoring that could cut the lip.

Frequently asked questions
- What size shaft does the DBH 8203 seal fit?
- It is sized for a 66.72 mm shaft, a 92.02 mm housing bore and a 12.70 mm height. Check all three against your equipment before installing a replacement.
- How do I ask for an equivalent to the 8203 seal?
- Send us the code 8203 or the shaft, housing and height dimensions of the seal you are replacing, plus a short description of the application. We will look for a match in the same radial shaft seal category.
- What is the Mz design on this seal?
- Mz refers to the construction of the seal: a sealing lip combined with a metal body that presses into the housing. Matching that designation matters when you replace the part, along with the elastomer type and spring.
