The DBH 8477 radial shaft seal is a lip seal designed to stop oil or grease from escaping on rotating shafts and to prevent dust and water from entering from the outside. It is press-fitted into the housing and runs on the shaft with a flexible lip that maintains contact. It is a common wear part in motors, pumps, gearboxes and reducers, where a small leak ends up affecting equipment operation.

This item is a seal from the DBH line, identified by part number 8477. Its dimensions are 13 mm shaft diameter, 20 mm housing diameter and 5.00 mm height. The Mx design corresponds to the seal's construction configuration, with a sealing lip and metal body for press fitting. It is a compact-section seal, intended for tight spaces where a taller seal will not fit.

It is used in equipment with small-diameter shafts: small electric motors, centrifugal pumps, gearboxes, compressors, machine tools and light-duty transmissions. It also appears in applications where lubricant must be retained while simultaneously blocking environmental dust. In all cases, it is advisable to verify that the shaft has no burrs or wear in the contact area, because that shortens the lip's life.

To select the seal, the first step is to confirm the three dimensions: shaft diameter, housing diameter and height. Then check the condition of the shaft and housing: if there are deep marks, the new seal will not seal properly. Installation is done with the lip lubricated and a tool that presses evenly on the body, without striking the lip. If the equipment operates at high temperature or speed, consult the lip material before replacing.

If part number 8477 is not available or you need a nearby size, an equivalent can be found by the three dimensions. In those cases, send us the dimensions of the old seal or a photo of the part and the housing. The part number stamped on the seal also helps. With that data, at MR Accesorios Industriales we look for the alternative that best fits the assembly.
