The DBH 6821 is a radial shaft seal from the DBH line that keeps lubricant contained and blocks contaminants from reaching rotating parts. It measures 55.40 mm at the shaft, 76.15 mm at the housing and 12.50 mm in height, which makes it a replacement item for specific assemblies. MR supplies this brand and can help you confirm the right seal for your equipment.
This seal carries the code 6821 within the DBH line. The Ms design refers to a particular lip and case arrangement, built to retain oil or grease where a shaft turns. Because the seal rides directly against the shaft and sits in the housing bore, its tolerances and materials have a direct effect on how the assembly performs.
You will find seals like the DBH 6821 in gearboxes, pumps, electric motors, transmission shafts and process equipment. They serve two purposes at once: holding lubricant in and keeping dust, water and particles out. In plants and maintenance operations, this kind of seal is a wear item that should be changed when a leak appears or when the equipment starts making unusual noise.
When selecting a replacement, confirm that the shaft and housing diameters match the seal and that the 12.50 mm height fits the cavity. The Ms design determines the lip profile and case type, so swapping it for a different design is not advisable without checking first. Install with lubricated lips, avoid impact on the sealing edge and inspect the shaft for burrs or wear that could shorten seal life.
If you need an equivalent to the 6821, send the complete code along with the shaft, housing and height measurements, plus a photo or sample of the old seal if you have one. That information lets us search within the same brand or in other lines we carry. We can also tell you whether the assembly can accept a slightly different height or diameter.
