The DBH 5345 is a radial shaft seal built to keep lubricant where it belongs and to keep dust, water and other contaminants out of rotating assemblies. It fits a 46.43 mm shaft, a 69.78 mm housing bore and a 12.30 mm width. The Lx configuration pairs a primary sealing lip with a secondary exclusion lip, which gives the seal an extra barrier in dirty or damp working conditions.

Reading the code is straightforward once you know the layout. The dimensions run shaft first, then housing bore, then width: 46.43 mm, 69.78 mm and 12.30 mm. The Lx designation tells you the seal has two lips rather than one, so it handles both lubricant retention and contaminant exclusion. A spring inside the seal keeps steady pressure against the shaft, and the lip compound is selected to stand up to mineral and synthetic oils.

You will find this seal in gearboxes, centrifugal pumps, electric motors, compressors and other power transmission equipment. In each case the goal is the same: hold the oil in, keep abrasives out, and protect the bearings and gears behind it. Agricultural machinery, mining equipment and process lines that need clean lubricant are also common homes for the DBH 5345. The second lip is what makes it a practical choice where dust or splash is present.

Installation matters as much as the part itself. Check that the shaft surface has the right hardness and a controlled finish, and that the housing bore is clean with no burrs or sharp edges. Put a light film of lubricant on the lip before pressing the seal in, and use a driver that pushes evenly on the outer diameter so the seal seats square. When you select a replacement, take rotation speed, operating temperature and the fluid being sealed into account. If the old seal failed early, look at shaft alignment and surface condition before fitting a new one.

If you are cross-referencing, send us the code 5345 or the three dimensions and we will check what is available in the radial seal range. We can also review other lip materials or spring options when the application calls for it. Quotes are handled by WhatsApp or email, and our team responds promptly with equivalents and selection help.
