Part number 6681 belongs to the DBH line of radial shaft seals, a lip seal built to keep lubricant in and contamination out of rotating assemblies. Its three key measurements are a 14.25 mm shaft, a 23.80 mm housing bore and a 7.00 mm width, which makes it a fit for smaller equipment where radial room is tight. MR supplies this brand within its seals and oil seals range.
Reading the code is straightforward once you know what the numbers describe. The 14.25 mm figure is the shaft the lip rides on, 23.80 mm is the bore the outer diameter presses into, and 7.00 mm is the installed width. The Lz designation identifies a single lip with a spring, a layout meant for rotating shafts that run with oil or grease present.
In service, the lip contacts the rotating shaft while the outside diameter stays fixed in the housing. That combination holds lubrication inside the assembly and blocks dust, water and chips from reaching bearings and gears. You will find seals of this size in small gearboxes, electric motors, water pumps, compressors, reducers and other power transmission equipment, as well as machine tools, refrigeration units and compact hydraulic systems.
Selection comes down to matching all three dimensions to the original part. The shaft should be ground, free of burrs, and hard enough and smooth enough to support long lip life, with 45 HRC as the usual reference. A chamfer at the housing entry helps the lip slide in without damage. Before installation, coat the lip with the same oil or grease the equipment uses, and keep sharp tools away from the sealing edge.
If the part number is not enough, send the dimensions of the old seal, a photo or the physical sample. The team can review equivalents and help confirm the right choice for your equipment. Quotes are handled by WhatsApp or email, and replies come back promptly.
