The DBH 6904 is a single-lip radial shaft seal with a spring and an outer metal case, identified by the Ms design. It keeps lubricant in and contaminants out of rotating shaft assemblies such as gearboxes, pumps, motors and transmission equipment running at moderate speeds. MR Industrial Accessories supplies this brand and can help you confirm the size and compound for your specific application.

This seal carries the code DBH 6904. Its three critical dimensions are a 50.77 mm shaft, a 66.60 mm housing bore and a 6.35 mm width. The 6904 number identifies the part within the DBH line. The Ms design means a single sealing lip with a spring, held in an outer metal case. These features make the seal suitable for press-fit installation in a housing while the shaft rotates inside it.

You will typically find a seal of this size in gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. In each case it does the same job: hold oil or grease within the assembly and block dust, water or particles from entering. It also appears in machine tools and continuous process equipment, where effective shaft sealing is essential for bearing life.

Before installing, check that the shaft and housing dimensions match the values listed. The shaft should be clean and free of burrs or marks, and it helps to lubricate the lip before insertion. Install the seal with the lip facing the fluid to be retained. If the shaft is worn, consider a seal with the lip in a different position. The compound you choose depends on the operating temperature and the fluid involved.

If you need an equivalent, send us the code 6904 or the shaft, housing and width dimensions. With that information we search for alternatives within the DBH line or other brands we supply. We can also advise on the Ms design and its variants for your type of installation. The more complete your equipment details, the more accurate our proposal will be.
