For rotating shafts where space is tight, the DBH 1247 oil seal provides radial sealing. It has a 17 mm shaft diameter, 34 mm housing diameter, and 4 mm height, and it features an Lt design. This seal keeps lubricant in and contaminants out. MR Industrial Accessories supplies this brand and can help you select the right seal for your equipment.

The DBH 1247 is a radial shaft seal from the DBH line. Its code is 1247, and its dimensions are 17.00 mm for the shaft, 34.00 mm for the housing, and 4.00 mm for the height. The Lt design means it has a single lip with a spring, intended for rotating shafts that are lubricated. The elastomer lip contacts the shaft, while the metal case is press-fit into the housing. This is a standard replacement item in the radial seals and oil seals category.

Seals of this size are commonly found in small centrifugal pumps, electric motors, gear reducers, gearboxes, and transmission equipment. They are also used on fan shafts, compressors, and machine tools. Their role is to prevent oil or grease from escaping and to block dust or water from entering. When the shaft and housing are in good condition, the seal helps protect bearings and extends the life of the assembly.

When installing a radial shaft seal, make sure the shaft is free of burrs or wear and that the housing is clean and not deformed. Apply some of the same oil or grease used in the equipment to the lip before insertion. Use a suitable support tube to tap the seal into place, and never strike the lip. The peripheral speed and operating temperature must stay within the limits of the elastomer. If the shaft has a deep groove, consider a different size or a wear sleeve.

If you need a seal equivalent to the DBH 1247, provide the code, the shaft, housing, and height measurements, and a photo of the old seal. With that information, we can look for alternatives in other brands or lines we carry. We can also advise you if the Lt design is not right for your equipment and a different lip type or material would work better. Our goal is to help you avoid downtime due to a sealing part.
