The DBH 8481 is a radial shaft lip seal that keeps oil or grease contained between a rotating shaft and its housing. It measures 63 mm at the shaft, 80 mm at the housing and 12 mm in height, and uses the Mx design. Pressed into crankcases, covers and gearboxes, it is one of the wear parts MR Industrial Accessories supplies to maintenance teams across the United States and Latin America.
In the DBH line, the code 8481 points to this particular size, while Mx describes a single lip with a spring. The seal is pressed into the housing bore and the lip rides against the shaft. Shaft diameter is 63 mm, housing diameter is 80 mm and overall height is 12.0 mm. The spring holds the lip in contact with the shaft to retain lubricant and block dust.
You will find this seal in gearboxes, centrifugal pumps, electric motors, transmission shafts and continuous process equipment. Its job is to stop oil from escaping and to keep contaminants away from bearings and gears. Because the lip eventually hardens or the shaft develops play, the seal is a replacement item: dripping or a visible wear groove means it is time to change it.
Selection and installation follow a few practical rules. The shaft must sit within the recommended tolerance and have a surface finish that will not damage the lip. The housing bore should be clean, free of burrs and with a sound entry chamfer. Lubricate the lip before pressing the seal in, make sure the spring faces the fluid side and avoid hitting the casing during installation.
If you need an equivalent, send the part number stamped on the old seal plus the shaft, housing and height measurements, and a photo of the assembly. From that we can search the DBH line or another brand we carry. We can also tell you whether Mx is the right choice or whether your operating conditions call for a different lip profile or material.
