The DBH 8647 oil seal is a single-lip radial shaft seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. Due to its dimensions —46 mm shaft, 59.10 mm housing and 12 mm height— it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales carries it as part of its seals and oil seals line.

The DBH 8647 is a radial shaft seal with an Lx design, featuring a sealing lip and a metal case. Its dimensions are 46 mm shaft diameter (d), 59.10 mm housing diameter (D) and 12.00 mm height (h). The lip runs on the rotating shaft and the outer diameter fits into the housing by interference. The designation 8647 identifies this size within the DBH line, and the code lets you order it without ambiguity.

Typical applications for an oil seal of these dimensions appear in equipment with transmission shafts: gearboxes, centrifugal pumps, electric motors, rollers and machine tools. It is also used as a closure in bearings and housings that need to keep grease in and contamination out. It is a wear part: when the lip hardens or the shaft gets marked, it starts losing oil and should be replaced before it damages the bearing.

To install it, check that the shaft is clean, free of burrs and deep marks, and that the sealing surface has the right hardness and finish. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, using a tube or press that bears on the outer diameter, never on the lip. If the housing has burrs or the seat is ovalized, the seal will not seal even if the size is correct. In that case, it is best to check the housing before installing the replacement.

If you cannot find code 8647 or need a nearby size, send us the dimensions of the old seal: shaft diameter, housing diameter and height. With those three data points we look for the equivalent in DBH or another brand in the same category. We can also advise you if the original seal has a special configuration, such as a double lip or dust guard, so that the replacement performs the same function.
