The DBH 5123 is a radial shaft seal from the DBH line, sized for a 15 mm shaft, a 28 mm housing bore and a 6.00 mm height. It is a single-lip seal with a metal case, press-fitted into a cylindrical housing, and it runs against the shaft to hold lubricant in and keep contaminants out. As a wear part, it is normally swapped out during planned maintenance on pumps, motors, gearboxes and similar machinery. MR Industrial Accessories supplies this brand and can help you match the seal to your application.

The part number 5123 sits in the DBH line, and the Lx design means one sealing lip with a metal outer body. The dimensions are: shaft 15 mm, housing bore 28 mm, height 6.00 mm. That size format is standard, so the seal is easy to find in catalogs and maintenance lists. It is a standard replacement item, not a made-to-order component.

You will typically see a seal this size in small centrifugal pumps, low-power electric motors, gear reducers, compressors, machine tools and transmission units. It also appears on fan, mixer and conveyor shafts that turn continuously. In all of these, it does two jobs: it stops oil or grease from escaping the bearing area, and it blocks dust, water and particles from getting in.

For correct installation, confirm the shaft is 15 mm and the housing is 28 mm, and check that the contact surfaces are free of burrs and scratches. Put a little lubricant on the lip, then seat the seal with the lip facing the fluid side. The 6.00 mm height must match the housing depth. If the shaft is worn, a seal with an extra lip may be worth considering. Speed, temperature and lubricant type all affect the final choice.
