The DBH 6671 is a radial shaft seal built to a 30 mm shaft, 42 mm housing bore and 6.00 mm height, with design A 115. It keeps lubricant in and dirt or moisture out of rotating assemblies, which helps protect bearings and bushings. Because the lip and running surface wear over time, a seal that shows marks or loses elasticity should be replaced before leaks start.

The code 6671 identifies this seal, and the three dimensions define its fit: shaft 30 mm, housing 42 mm, height 6.00 mm. Design A 115 indicates a single lip with a spring, a common configuration for rotating shafts that run with lubrication. Before installing a replacement, confirm that all three measurements match the bore and shaft you are working on.

You will find seals of this type in gearboxes, centrifugal pumps, electric motors, drive shafts and process equipment. Their job is twofold: hold the oil or grease inside the assembly and block dust, water or particles from entering. The compact 6 mm height suits locations where axial space is tight but reliable sealing is still required at moderate to high speeds.

Installation starts with a clean housing and shaft. Look for burrs or deep marks, and lubricate the lip before pressing the seal in. It should go in perpendicular, using a tube or shim that contacts the outer diameter rather than striking the lip. If the shaft itself is worn, a sleeve may be the better route. Speed, temperature and the fluid being sealed all affect the final selection.

If you are looking for an equivalent, send the code 6671 or the dimensions 30 x 42 x 6 mm along with your application details. We can review options in other brands or lip configurations within the same radial shaft seal category. The more you tell us about fluid, temperature, speed and shaft condition, the closer the match will be.
